Subscribers

• add_subscriber - Add a new subscriber by email, or by phone alone for a phone-only (SMS) contact; its status is creation-only, so use update_subscriber for an existing contact. The subscribers:write scope covers a nonempty listIds array in this call; omit it to let a new contact follow the workspace default lists while an existing contact keeps its memberships, or pass [] to join no list. The data-ingest presets support explicit lists in this call. Imports into explicit lists and dedicated list membership tools still require lists:write. Pass createdAt when importing from another platform to keep the contact’s original signup date, so date-relative segments are right immediately; an existing contact’s date only ever moves earlier, and supplying it skips sequence enrollment by default. Pass enrollInSequences: true to override that default with an API key that has automations:trigger
• create_subscriber_import - Queue up to 5,000 full CRM subscriber records in one call, including names, external IDs, phone numbers, tags, lists, statuses, custom attributes, and a per-record createdAt signup date. A nonempty listIds array requires lists:write. Workspace-default opt-in can require automations:trigger for active contacts, and double opt-in always requires it. Pass idempotencyKey from retry loops so a resent request returns the already-queued import instead of creating a second batch
• get_subscriber_import - Check import progress and row-level outcome counts. Every excluded row is explained: skippedReasons sums to skippedCount and failedReasons sums to failedCount, so a migration can be proven complete without inspecting individual contacts
• update_subscriber - Update profile fields, attributes, tags, or global status; the legacy attributes spelling merges keys into the existing custom-attribute map, while the REST-compatible customAttributes spelling replaces the public map and removes unspecified keys. status: "unsubscribed" suppresses future marketing while preserving history. firstName, lastName, timezone, and phone are native profile fields, so set them here rather than as custom attributes - timezone takes an IANA identifier (e.g. America/New_York) and enables recipient-local campaign delivery - a national-format number needs phoneCountry (for example IT), and changing a number resets SMS consent unless you send smsConsent in the same call
• remove_subscriber - Unsubscribe while preserving history, or permanently delete only with hardDelete: true
• get_subscriber - Get subscriber details
• list_subscriber_attributes - List the custom attribute names in use across the account, each with valueType (string, number, or boolean), isArray, mixedTypes, an example sampleValue, and sampledContacts. When mixedTypes is true, contacts hold different types for the key and valueType is string. Call it before add_subscriber or update_subscriber to reuse existing names and send matching types, for example a zip code as the string "02134". Pass includeNested: true for paths such as profile.tier
• search_subscribers - Search by free-text query, tags, lists, segments, or a custom attribute. Omit limit and the tool walks every page for you and returns all matches in one call. To read a large audience in chunks instead, pass limit and follow pagination.nextCursor until pagination.hasMore is false; offset and page also work below 1,000,000 skipped matches and are what pagination.nextOffset is for when nextCursor is null. Use cursors for deeper audiences. Filter on a custom attribute with attribute plus attributeValue and an optional attributeOperator (is, contains, gt, gte, lt, lte, or is_not_empty); is_not_empty needs no value and matches every contact that has the attribute set. Attribute filters cannot be combined with segmentId - create a segment for compound or is_not/is_empty attribute rules. Each subscriber carries unsubscribedAt, the date the contact opted out; use it rather than updatedAt, which any later tag or attribute write moves. Narrow to a window of opt-outs with unsubscribedAfter and unsubscribedBefore, which skip contacts that carry no opt-out date - active contacts and imports with no known date. Bare dates use UTC midnight; datetimes must include Z or an explicit offset
• trigger_subscriber_event - Emit a custom event for one subscriber exactly as an integration would. This is the supported way to exercise event triggers, matching-field idempotency, branch conditions, and stop conditions end to end without waiting for real traffic. Pass occurredAt to backfill an event that already happened: more than an hour in the past it is recorded as history, counted by segments and the timeline but running no sequences, sync rules, waiting steps or webhooks. Never use it to test a live automation, since the side effects you are testing will not run. Pass your own eventId to make a retry safe: a repeated live event returns the existing event with duplicate: true, while a repeated historical event stays in the events array and increments duplicates
• trigger_subscriber_events - Emit several events for one subscriber in order, up to 500 per call. When every event carries an occurredAt more than an hour old the batch imports as history in one idempotent write; add your own eventId so a re-run writes nothing new

• import_subscriber_events - Record up to 25 events for many subscribers, each carrying email or an existing contact’s externalId plus a source-owned eventId. Contacts whose rows are all more than an hour old import silently as history; any recent row makes that contact’s whole group live. Retrying reuses one receipt and repairs downstream work idempotently
• bulk_add_subscriber_tags / bulk_remove_subscriber_tags - Add or remove tags across up to 500 existing subscribers identified by emails, externalIds, or subscriberIds. Built for reconciling derived-tag backlogs: unknown identifiers come back in notFound instead of creating contacts, and tag automations stay off unless you pass triggerAutomations: true

​

Accounts

• list_accounts - List accounts with search across name, external ID and domain, plus paging and sorting by updatedAt, createdAt, name, memberCount or lastEventAt
• get_account_by_external_id - Get one account by the customer-owned organization id, with up to 100 members and their roles (owners first)
• upsert_account - Create or update an account by external ID. Attributes merge into the stored map (null deletes a key; replaceAttributes: true replaces everything). Optional members are added in the same call
• delete_account - Delete an account and its memberships; contacts are kept and their account.* values cleared
• list_account_members - List members with roles
• add_account_member / remove_account_member - Attach or detach a contact by email or subscriberExternalId. Adding a new email creates the contact; re-adding with a role updates it, without one keeps the current role
• trigger_account_event - Record an event on the account (for example trial_ending) and deliver it to owners (default, falling back to admins), admins, all or none. Each recipient gets a normal contact event carrying event.account.*, so sequences, sync rules and matching-field enrollment on account.externalId (once per account) all work. Pass eventId for idempotent retries and occurredAt (ISO 8601) to preserve the original event time
• list_account_events - Recent account timeline events, newest first
• list_account_suggestions - Read-only: work email domains several contacts share (minContacts, default 3; limit, default 25), with up to 10 sampleEmails, skipping personal and disposable providers, your sending domains, domains where a contact already belongs to an account and domains an account already uses
• accept_account_suggestions - Create accounts for up to 25 domains the user confirmed. Each domain becomes an account (external ID and domain set to the domain) with its unassigned contacts as members, or its contacts join the one account already using that domain. Results are created, updated or skipped (no_contacts, multiple_accounts, already_in_account); retries are safe, and no sync rules or segment-entered sequences run
• detect_account_organization_ids - Read-only: event properties and contact attributes that hold your organization ID, such as workspaceId, with how many organizations each has and the matching nameKey
• preview_accounts_from_organization_id - Read-only: the biggest accounts a propertyKey would create, each with the name it would get (from nameKey, otherwise its contacts’ shared work email domain), domain, contactCount and sampleEmails. Show it to the user before creating anything
• create_accounts_from_organization_id - Start a background run that creates one account per organization ID and adds its contacts as members, after the user confirms the preview. Returns jobId and alreadyRunning; nothing is sent, existing names and roles are kept, and reruns are safe
• get_account_organization_id_job - Check that run: queued, running, completed with counts, or failed with the error

​

Lists

• list_lists - List subscriber lists. Each list includes subscriberCount (current members of any status) and activeSubscriberCount (current members with status=active). Members who unsubscribed from the list are not counted
• create_list - Create a subscriber list
• update_list - Update a list’s name, description, or privacy
• delete_list - Permanently delete a list and all of its memberships; subscribers themselves are kept
• add_subscribers_to_list - Bulk add up to 500 subscribers to a list from an email array
• remove_subscribers_from_list - Remove up to 500 subscribers from a list by email; subscribers stay in your audience and unmatched emails are returned in notFound

​

Campaigns

• list_campaigns - List campaigns with status, label, limit, and offset filters, including reviewer feedback in rejectionComment for rejected campaigns. Each item carries delivery pacing (sendTimeOptimization, sendTimeWindowHours, spreadOverHours, sendInRecipientTimezone, scheduledTimezone) so a company-wide Send Time Optimization audit does not need one get_campaign call each. STO is campaign-only; sequences use sendingWindow. Results are paginated: the default page size is 50 and limit is capped at 100. Read the returned pagination object (limit, offset, count, total, hasMore) and keep paging with offset while hasMore is true - one call does not necessarily return every campaign
• get_campaign - Get campaign details and stats, including the saved audience in targetLists (null when targeting is still unset), the linked email body in emailId (the same record the template tools read; reusable as templateId in create_campaign, null for SMS campaigns), and reviewer feedback in rejectionComment for rejected campaigns. rejectionComment stays null while a campaign is still in waiting_approval. Finished campaigns also report recorded pacing through spreadOverHours, sendTimeOptimization, and sendTimeWindowHours, plus the recipient cap in maxRecipients (null for the whole audience), alongside sentAt - which is stamped when the last recipient is handed off for native sends, so on a paced send it marks the end of the delivery window. Imported campaigns may not include source-provider pacing metadata, so absent pacing fields do not prove delivery happened all at once. Note that computedLists is email personalization (product lists rendered inside the email), not audience targeting
• get_campaign_audience - Resolve exactly who a campaign will reach: targeting kind, resolved list and segment names (with a missing flag for deleted references), filters, include/exclude rules, a plain-language summary, and a live recipient count. isUnset: true means scheduling would send to every active subscriber
• list_campaign_goals / create_campaign_goal / update_campaign_goal / delete_campaign_goal - Manage persisted event, subscriber-attribute, or tag-applied conversion goals attached to one campaign. These appear on the campaign report as named conversion steps after sent/opened/clicked
• create_campaign - Create a campaign from a prompt, raw HTML, or Sequenzy blocks; native blocks include Poll and NPS surveys. Prompt generation saves the generated subject, preview text, company logo/footer, and uses the company font. Pass emailPreset: "branded" | "minimal" to set Style > Format for native blocks; this is separate from prompt-generation style, cannot be combined with html, and is unsupported when the whole email is one raw HTML block. Applying minimal removes standalone logos; restoring branded generates a new logo unless the authored logo block is sent again. Defaults to draft, with status: "sent" available for archived/imported sent campaigns. Pass targetLists (or the segmentId/listIds shorthands) to save the audience on the draft, or omit them and choose it in update_campaign or schedule_campaign. Set the sending identity either with senderProfileId/replyProfileId from list_sender_profiles - each already carries its own display name, so send them without fromEmail/fromName and replyTo/replyToName - or with fromEmail/replyTo plus optional fromName/replyToName to name a profile Sequenzy creates for that address
• update_campaign - Edit a draft, including reply-to settings, raw HTML, or Sequenzy blocks such as Poll and NPS surveys. Pass emailPreset to change Style > Format without rewriting copy, subject to the same native-block and logo-loss rules as create_campaign. Accepts targetLists (or the segmentId/listIds shorthands) to retarget the draft, or targetLists: null to clear saved targeting. Sending identity follows the same rule as create_campaign: a profile ID replaces both the address and the display name. Set sendTimeOptimization and sendTimeWindowHours (1-24, default 12) on the draft; they are used when the campaign is later scheduled unless schedule_campaign overrides them. STO is campaign-only - there is no company or sequence toggle. maxRecipients (1-10,000,000, or null to clear) caps the send to the first N matching subscribers by subscriber id
• schedule_campaign - Schedule a draft or already scheduled campaign; pass targetLists or the listIds shorthand to pick the audience at schedule time (omitting both reuses saved targeting, or defaults to every active subscriber), and recurringInterval: "weekly" or "monthly" to repeat it automatically, re-evaluating audience membership at every run. Pass sendTimeOptimization: true to deliver each recipient at their predicted best hour within sendTimeWindowHours of scheduledAt (default 12h, max 24); this is campaign-only and is not available on sequences. spreadOverHours takes precedence and turns STO off. maxRecipients sends to at most that many audience members (omit to keep the draft’s saved cap, null to clear it; recipients already reached count against it on resume). Pass sendInRecipientTimezone: true with scheduledTimezone (the IANA zone the scheduledAt wall time refers to) to deliver at that wall-clock time in each recipient’s own stored timezone; contacts without a timezone receive the campaign at scheduledAt itself. The returned campaign.status is either scheduled or waiting_approval. waiting_approval means the campaign was held for safety review and nothing sends until a reviewer approves it - most common on new accounts and recently registered sending domains. It is a successful outcome, not an error, and scheduling again does not clear it; check the campaign with get_campaign instead
• unschedule_campaign - Remove a scheduled send and recurrence, returning the campaign to an editable draft that can be scheduled again
• send_test_email - Send test to single address
• render_email - Render a campaign, sequence email step, or template to the exact email-safe HTML that would be sent, for embedding a visual preview in an external dashboard or builder, or for checking merge tags before anyone is enrolled. Pass exactly one of campaignId, sequenceId plus nodeId, or templateId. unresolvedMergeTags lists every tag that did not resolve, with reason unknown (nothing provides that name, so it stays empty for every recipient) or no_value (recognized or unverifiable, but blank for this contact) - the HTML alone cannot tell them apart. An unknown name is reported even when a default filter supplied text in its place, because that fallback then reaches every recipient while the HTML looks correctly personalized. A name is only called unknown when the render had a source to check it against. Without the contact’s attributes nothing is checkable - a bare {{plan}} reads the same attribute map as {{subscriber.plan}} - so pass a stored subscriberId or an inline subscriber with customAttributes. Beyond that, {{event.*}} needs sample event properties in variables, since a real send fills those from the enrolling event, and {{recommendedProducts.*}} needs a stored subscriberId the catalog has something to recommend for. Rendering a transactional email needs variables, since its tags come from the variables of each send call and carry no prefix marking them. Otherwise they report no_value rather than being called typos. An optional attribute this contact never had set is kept out of unknown by checking the names other contacts in the account carry, which needs the subscribers:read scope. A sequence step downstream of a create-discount step renders {{discount.*}} from that step’s real configuration with a placeholder TEST-CODE for the code; on a step some paths reach without running that discount step, and on a standalone template, {{discount.*}} reports no_value instead of being called a typo. unevaluatedConditions does the same job for conditional blocks: a condition on stored subscriber state (tag, segment, list, status, event, purchases, engagement) can only be evaluated for a stored subscriberId, or for a tag condition an inline subscriber carrying tags, and anything else renders as false - indistinguishable in the HTML from a contact who genuinely does not match. Read-only: it never sends or modifies anything
• cancel_campaign - Cancel a scheduled, paused, or sending campaign; remaining emails are not sent and the campaign cannot be restarted
• pause_campaign - Pause a campaign that is currently sending
• resume_campaign - Resume a paused campaign, optionally spreading the remaining delivery over 1-72 hours with spreadOverHours
• duplicate_campaign - Duplicate a campaign as a new draft. mode: "campaign" (default) copies the campaign and its email, "ab_test" also copies the A/B test with all variants, and "variant" copies a single variant’s content (requires variantId)
• resend_campaign_to_non_openers - Create a draft that resends a sent campaign to everyone in the same audience who didn’t open it. Available 6 hours after the campaign finishes sending, and never for imported already-sent campaigns (Sequenzy has no opens for a send it did not deliver); returns the draft and an estimate of how many subscribers haven’t opened the original. The draft must be scheduled or sent separately Every audience format keeps opener exclusions that manual additions cannot override. Resending a resend also preserves exclusions from earlier campaigns. Your audience is evaluated live, so new members can qualify even if they never received the original. If an older resend draft lacks excludedCampaignOpenerIds, recreate it from the original campaign and review the new draft before scheduling.
• share_campaign - Create (or fetch) the campaign’s public “view in browser” link. The hosted page renders an anonymized copy - sample contact, inert unsubscribe link, no open/click tracking - so the URL is safe to forward to anyone. Idempotent: an already-active link is returned with created: false instead of being rotated. get_campaign reports the current link as shareUrl
• unshare_campaign - Revoke the public link; the shared URL returns 404 immediately, and sharing again later mints a different URL
• delete_campaign - Permanently delete a campaign; sending, scheduled, or paused campaigns must be cancelled with cancel_campaign first

​

Saved Forms

• list_forms - List saved forms, audience settings, and public action URLs
• create_form - Create and publish a form scoped to one or more list IDs, optionally with brand theme overrides
• update_form - Rename a form, retarget its audience, edit its copy, restyle its theme, or replace its content blocks (read the current blocks via list_forms first)
• get_form_embed - Get the action URL, hosted JavaScript, native form, and fetch example

​

Popups

• list_popups - List popups with their status, counts, and engagement rates. Content blocks are omitted unless you pass includeContent, so listing a workspace stays cheap
• get_popup - Get one popup’s complete content blocks, trigger, targeting, schedule, frequency, and theme
• create_popup - Create a popup from a starting template and get its embed script; published by default
• update_popup - Rename, publish or unpublish via status, retarget, retime, edit copy, restyle, or replace content blocks
• duplicate_popup - Copy a popup into a new draft with its own counts, leaving the original live
• get_popup_embed - Get the script URL plus HTML, React/Next.js, WordPress, and Shopify snippets
• delete_popup - Permanently delete a popup and its view and conversion counts

​

Landing Pages

• list_landing_pages - List landing pages with status, metrics, content, and URLs
• get_landing_page - Get landing page details, editor content, lifetime metrics, public URLs, and a signed previewUrl that works for drafts. Use get_landing_page_stats for unique visits, referrers, and crawler hits
• get_landing_page_stats - Mailchimp-style report: visits, unique visits, clicks, subscribes, conversion rate, daily histogram, referrers, UTM sources, and crawler hits. Preview URLs and the editor are never counted
• render_landing_page - Return a visitor-facing preview URL for a landing page without publishing it. Drafts keep publicUrl null; open previewUrl to check layout, copy, and #form anchors. The preview is not indexed and draft forms do not collect contacts
• create_landing_page - Create a draft landing page from default template content or supplied JSON
• update_landing_page - Edit landing page name, slug, or full editor-compatible content
• publish_landing_page - Publish a landing page, optionally saving name, slug, or content first
• unpublish_landing_page - Return a landing page to draft, optionally saving edits first
• duplicate_landing_page - Copy a landing page into a new draft with its own slug and stats
• delete_landing_page - Delete a landing page
• connect_landing_page_domain - Connect a workspace domain, or provide landingPageId for a hostname dedicated to one page
• update_landing_page_domain_settings - Update or verify workspace/page domain settings; provide the same landingPageId for a dedicated page domain
• remove_landing_page_domain - Remove a dedicated page domain while preserving its workspace and Sequenzy fallback URLs

​

Company

• create_api_key - Create a company API key and return its one-time secret on the standard MCP surface. It is omitted from the OpenAI-reviewed surface; use request_api_key_handoff there
• request_api_key_handoff - Prepare an owner-confirmed link that opens the dashboard create-key form prefilled with a suggested name and permissions. Use it when key management is blocked because the active key lacks api_keys:manage. It creates nothing and never returns a key: hand the URL to the workspace owner and stop. Pass replaceApiKeyId (or "current") to rotate, and the dashboard offers to revoke the predecessor once the replacement exists. Needs only account:read
• list_api_keys - List company API keys as non-secret metadata, including IDs, prefixes, permission receipts, usage timestamps, and the active-key marker
• update_api_key - Rename a company API key or replace its permissions in place, without issuing a new key. Reach for this when a call fails with a missing-scope error: the key value is unchanged, so no client has to be re-wired, and added permissions apply on the next retry. Removed permissions may remain usable for up to five minutes while API caches expire. preset and scopes replace the whole selection rather than merging into it, so call list_api_keys first
• revoke_api_key - Permanently revoke an exact company API key by ID after checking it with list_api_keys (delete_api_key is a compatibility alias)
• get_company - Get company details, product info, brand colors, AI writing context, effective localization settings, the read-only emailBranding entitlement, and defaultSubscriberListIds - the workspace default lists new contacts join when nothing targets them explicitly. emailBranding.visible reports whether “Sent with Sequenzy” is added to future sends; the reason, tier, subscription status, required action, and subscriptionUrl let an agent explain the entitlement and hand a billing-authorized user to the real Account -> Subscription page. Branding is injected at render/send time, so a paid entitlement removes it from future sends by existing live sequences without editing their blocks. It is not a writable update_company setting. A JSON null for defaultSubscriberListIds is every current and future list, not an empty selection; [] is no list at all. An ordinary profile or attribute upsert for an active contact keeps that contact’s memberships unless it names lists explicitly; capture submissions and explicit lifecycle reactivations can reapply target or default lists. Change the setting with update_company. Read it before connecting an integration that has no per-integration list targeting of its own (Dodo Payments, PostHog, Polar, Paddle, and similar), because live contacts and payment-provider backfills land there. PostHog history imports are different: contacts created by that import have no list memberships. Send Time Optimization is not a company setting; audit campaigns with list_campaigns or get_campaign
• get_app_urls - Generate dashboard links for resources and company administration. When a company is resolved, the result includes the canonical subscription URL. The settingsTab values billing and subscription are compatibility aliases for Account -> Subscription; they do not invent a nonexistent Settings tab
• update_company - Edit product info, brand context, the brand emailDesignPrompt (art direction for AI-designed emails - layout, density, imagery, CTA prominence, separate from toneVoice; when empty, the next email generation prefills it with the direction derived from the brand, and an empty string clears it so the next generation writes a fresh one), and the default email theme (emailTheme accepts partial updates; null resets it - to restyle a single sequence email instead, patch that step’s emailTheme with update_sequence_node), or set account-wide fromEmail and replyTo defaults (From domains must be verified); send fromName or replyToName alone to rename the existing default profile’s display name, or pair them with senderProfileId / replyProfileId from list_sender_profiles to pick and rename a specific profile. Set defaultSubscriberListIds to choose which lists new contacts join when nothing targets them explicitly - forms, API writes, events, tag actions, imports, and every integration without its own targeting. The three states differ: null is every current and future list, [] is no list at all, and an array is exactly those lists. Unknown or foreign list IDs are rejected rather than skipped, and the change applies only to later writes - nobody is moved or removed retroactively, so a list already filled by a backfill still needs remove_subscribers_from_list. Profile, branding, and AI-context fields need company_profile:manage (included in Safer agent access); the sending-identity, reply-tracking, and defaultSubscriberListIds fields need companies:manage
• add_sending_domain - Add a sending domain and return the SPF, DKIM, MAIL FROM, inbound and optional company tracking CNAME records for setup. Optional mailFromPrefix chooses the bounce subdomain (add_website remains as a compatibility alias)
• get_tracking_domain - Read the company tracking domain, its status, whether links use it now, and its CNAME record
• set_tracking_domain - Set or change the company tracking domain every sending domain uses for tracked links and opens. Any subdomain works; it never blocks sending, and changing it keeps links in emails already sent working while the old CNAME stays
• verify_tracking_domain - Check the company tracking domain’s CNAME and HTTPS certificate now
• remove_tracking_domain - Remove the company tracking domain; links in emails already sent through it stop working
• configure_sending_domain - Deprecated: set <trackingPrefix>.<domain> as the company tracking domain when none is set; prefer set_tracking_domain
• list_websites / check_website - Read stored aggregate, SPF, DKIM, MAIL FROM status, the envelope sender domain, and the Apple Email Source domains derived from sender profiles
• verify_sending_domain - Run a fresh DNS verification and return verified separately from readyToSend and selected home-transport readiness
• get_email_design_system - Get the visual identity every AI-generated email renders inside: the design code (kicker style, title alignment, button shape, divider style, density, sanctioned opener treatments) and the composition spine (hero-led | editorial | product-spec). The identity is stored as the company’s design direction text; the tool returns the parsed tokens, the raw text, and isDefault while the identity is still purely derived from brand context
• update_email_design_system - Adjust that identity (partial update) or reset it to the brand-derived defaults; the change is written into the design direction text (custom prose is preserved) and applies to every future AI email generation and sequence enrichment. Requires company_profile:manage
• get_sync_rules - Get the automatic tag changes applied when events fire, plus whether the optional platform preset is active
• update_sync_rules - Replace the full sync rule set ([] disables rules; null opts into the inherited SaaS/ecommerce preset); rules support subscriber-tag conditions and a product match (tags, collections, product types, vendors) for commerce events
• get_shopify_automation_settings - Get the connected Shopify store’s browse-abandonment, cart-abandonment, and price-drop settings with defaults applied
• update_shopify_automation_settings - Update browse-abandonment, cart-abandonment, and/or price-drop settings (partial update; null resets a section to the defaults)
• list_integrations - List connected integrations (Stripe, Shopify, Supabase, Clerk, ad platforms, and so on) with connection state, sync health, last sync time, and last sync error. lastSyncSkipped reports records the last store sync could not import normally, split into profiles that were kept but cannot receive email and records that were not imported at all. Credentials, access tokens, and webhook secrets are never returned; the OpenAI-reviewed surface also removes raw sync-error detail
• get_integration - Inspect one connected integration in depth: what it syncs, every event it emits and when, the tags each event applies through the account’s sync rules, which sequences trigger on each event, 24h webhook activity, and prioritized recommendations. unusedEvents lists the events nothing acts on yet, availableActions says what can be called on it right now, ingestion reports the bulk sync state and which lists new contacts land on (with names), Shopify pixel carries the live storefront tracking state, and Webflow webflowCapture reports the exact selected native forms, retained fields, required double opt-in, list IDs, sequence toggle, webhook state, and schema fetch time. An empty webflowCapture.forms means capture is off. For Attio, details.mappedListCount 0 plus an attio_lists_unmapped recommendation means list joins are not synced until you map lists with update_attio_settings
• list_integration_capabilities - Describe what each provider does whether or not it is connected: category, connect method, what it syncs, every event with the moment that triggers it, attributes written, supported actions, availability, and caveats. Coverage differs sharply - only Shopify has storefront browse tracking, only Stripe and Chargebee cover the full trial lifecycle - so check here instead of assuming an event exists
• get_event_schema - Read what a built-in event payload actually contains: a real example payload per provider, plus every property path with its type, the merge tag that resolves it, and a note wherever the sample alone is ambiguous. Omit eventName to list every documented event. documented: false means no sample is published, never that the event name is invalid - custom events carry exactly the properties you send
• connect_integration - Connect an API-key or webhook-secret provider on the standard MCP surface (Polar, Paddle, Dodo, Lemon Squeezy, Whop, Creem, Chargebee, Clerk, PostHog, Segment, Affonso, or Attio). Credentials are validated where possible, stored encrypted, and never returned; payment providers queue their initial revenue backfill, and PostHog and Segment can import event history. The response includes the webhook URL to configure at the provider with the same secret. It is omitted from the OpenAI-reviewed surface; complete setup in the dashboard or local CLI instead
• list_integration_activity - Recent integration webhook and sync activity with action, status, event type, matched contact, and error. The log to read when an integration says connected but nothing is arriving. Retained 24 hours; payloads are sanitized so no credentials appear
• disconnect_integration - Disconnect Lemon Squeezy and remove its managed webhook. Inspect cleanupWarning and repeat the call to retry cleanup; local ingestion is already stopped. Other providers disconnect from the dashboard
• set_integration_sync_enabled - Turn bulk imports and backfills on or off. Disabling keeps the connection, credentials, and live webhook delivery active. Does not disconnect the integration, and does not stop it creating contacts
• set_integration_list_targeting - Choose which lists the contacts an integration creates join. This is the tool for “stop this integration adding people to my marketing lists”: set_integration_sync_enabled only pauses bulk backfills and leaves the live webhook writing. Affects list membership only on future provider writes - null falls back to the workspace default lists, [] joins none, and nobody is ever removed from a list. Webflow deliberately rejects null; use [] or explicit list IDs, and configure its native forms, field allowlists, required double opt-in, and sequence enrollment in the dashboard. With no selected Webflow forms, capture is off and no contacts are created. Wix/Webflow submissions, Shopify customer updates, and Supabase resubscriptions can add existing contacts to new targets; Stripe targeting applies only when its webhook creates a subscriber. It does not stop contacts being created, attributes syncing, sync-rule tags, or default any_contact enrollments, which fire precisely because the contact joined no list. Explicit any_list and specific-list sequences require a matching membership and do not enroll a list-less contact; pair this tool with pause_sequence_enrollments when any_contact enrollment must stop too. Honored by Supabase, Stripe, Shopify, Wix, and Webflow. For a provider that is not on that list (Dodo Payments, PostHog, Polar, Paddle, WooCommerce, and similar), this tool returns an error and live contacts instead follow the workspace defaults - read and change those with defaultSubscriberListIds on get_company / update_company. A JSON null on that field means every list, not none; [] means none, remembering that the default is workspace-wide and repoints every other untargeted contact source too. PostHog history imports are an exception and create contacts without list memberships. Needs integrations:manage, which Safer agent access deliberately withholds
• sync_integration - Queue a manual re-sync: customers and revenue for a payment provider (Stripe, Polar, Paddle, Dodo, Lemon Squeezy, Creem, Chargebee, Whop), the user backfill for Supabase, or the event-history import for PostHog and Segment. The Supabase run reads the table already configured for that integration and cannot be pointed elsewhere; run it before a campaign that needs names or plan attributes on users who existed before the trigger was installed. The PostHog and Segment runs are the supported way to retry an event-history import that failed or was interrupted: they restart from the beginning with the stored credentials, and already-imported events dedupe. Returns immediately; poll get_integration for syncStatus. Other providers re-sync from the dashboard
• get_integration_pixel - Check whether a Shopify store’s storefront tracking pixel is installed and reporting to this account. Read live from Shopify on every call, because a merchant can remove the pixel without Sequenzy hearing about it. pixel.healthy is the field to branch on, pixel.error distinguishes a confirmed outage from an unknown Shopify read, and dependentEvents names the events that rely on the pixel. Shopify only
• activate_integration_pixel - Install the storefront pixel, or repoint an existing one at this account. Idempotent (changed: false when already live). Events start arriving on the next storefront visit and nothing is backfilled, so run it before building the sequence. Fails with a message naming the reconnect step when the store granted an older permission set
• get_attio_mapping - Inspect a connected Attio integration’s list mapping: Sequenzy lists, live Attio people-lists (id, api slug, name), the saved listMap, and mappedListCount. Call this when Attio is connected but mappings are empty, before update_attio_settings, so you have Attio list ids instead of asking the user to paste UUIDs. Reads Attio live. Attio only
• update_attio_settings - Set which Sequenzy lists sync into which Attio people-lists using the stored access token. Does not require the secret again — do not reconnect just to change mappings. listMap is a full replacement ({} clears every mapping). Unmapped lists are not synced; unmapping does not remove anyone from Attio. Needs integrations:manage, which Safer agent access deliberately withholds
• list_web_tracking_keys - List the publishable keys that let a non-Shopify website send on-site events into this workspace. Each returns its origin allowlist, unrestricted, lastUsedAt, and a paste-ready installSnippet. A key with lastUsedAt: null has not successfully authenticated an event yet; check deployment, instrumentation or traffic, and the origin allowlist
• get_web_tracking_key - One key with its install snippet and ingest endpoint. Use it to hand over the exact script tag rather than rebuilding one, since the snippet embeds both the key and the workspace id
• create_web_tracking_key - Create a publishable key and return the install snippet. This is what turns on product views, cart activity, and browse abandonment for a site that is not Shopify or WooCommerce. Always pass allowedOrigins; an empty allowlist accepts events from any site. Nothing is backfilled for the period before the snippet is deployed
• update_web_tracking_key - Rename a key, replace its origins (the list is replaced, not appended), or revoke it with isActive: false. Revoking preserves the key value so the matching snippet can still be found on the site
• delete_web_tracking_key - Permanently delete a key. Any page still running the snippet starts being rejected, so the snippet must come off the site too
• list_sender_profiles - List sender (From) and reply-to profiles, which are the account defaults, and whether each sender address sits on a verified sending domain
• update_sender_profile - Rename one sender or reply-to profile in place without changing which profile is the account default. Use it to standardize a display name across the several identities a mailbox can carry (for example Viraj from SnapCount down to SnapCount); pass type: "reply" for a reply-to profile. Only the name changes - the address, its sending domain, and the default From/Reply-To selection are untouched. To change which profile is the default, use update_company instead. Requires companies:manage
• delete_sender_profile - Permanently delete one sender (From) profile. It refuses to delete the last sender or a profile used by a live campaign, active sequence (including a step override), or transactional email. Eligible draft and rejected campaigns plus the account default move to the best remaining sender when needed; review fallbackSenderProfileId before sending. Reply-to profiles are not supported. Requires companies:manage
• get_notification_preferences - Get which account notifications Sequenzy emails the API key’s own user for this company (new subscriber, form submitted, campaign finished, weekly report), with the modes each event supports and the platform defaults
• update_notification_preferences - Change those settings. Modes are off, instant, daily, and weekly; daily is only valid for new_subscriber and weekly only for weekly_report. Instant form-submission notifications stop after 50 per workspace per UTC day. The Monday weekly report is on by default for the workspace owner (off for invited members until they opt in) and only sent for weeks with more than 10 emails sent; set weekly_report to off to stop it. Useful before a large migration, though imports never trigger new-subscriber notifications and busy days fall back to a daily summary automatically. Never reads or writes a teammate’s settings
• get_tracking_settings - Get open/click/unsubscribe tracking flags, the opt-in strictBotFilteringEnabled bot-detection flag, the default attribution window, automatic UTM tagging, the company tracking domain and its status, inbound reply-tracking settings, and the consent block with doubleOptInEnabled, the confirmation email ID, and the post-confirmation redirect URL
• update_tracking_settings - Turn open, click, and unsubscribe tracking on or off account-wide, opt in or out of strictBotFilteringEnabled, set the default attribution window, require double opt-in for new contacts with doubleOptInEnabled, set where the hosted confirmation page sends subscribers after they confirm with doubleOptInRedirectUrl (null keeps them on the branded confirmation page), and configure automatic UTM tagging (autoUtmSettings merges over the stored templates; a null field stops that parameter, and null for the whole object resets them to the defaults). Applies to emails sent afterwards; reply tracking stays on update_company. Enabling doubleOptInEnabled requires a sender profile and provisions the confirmation email automatically; it does not change contacts that are already active

• get_sending_status - Check whether company-level sending is active, paused, or suspended, why, and what it takes to restore it. Returns the pause reason and reason kind, the automated sender-health review state, whether one-click resume is available (and if not, which gate is blocking it), the enforcement counts and thresholds for permanent bounces, temporary bounces, and complaints, and ordered remediation steps. Requires only account:read
• resume_sending - Restore sending paused by a high permanent-bounce rate, after fixing the cause. Requires listSanitizationConfirmed: true, the companies:manage scope, and owner or admin access. It is a client of the same control the dashboard uses, not a bypass: only a permanent-bounce pause qualifies, the automated review must have cleared it, and it never removes suppressions

​

Sequences

• list_sequences - List sequences with dashboard-compatible status, search, label, limit, and offset filters. Branch on effectiveStatus (draft, live, enrollment_paused, paused, archived) rather than status, which reads active even when new enrollments are paused; acceptsNewEnrollments, processesExistingEnrollments, and the plain-language effectiveStatusSummary are returned alongside it. The legacy triggerConfig.active flag is not read by the runtime and now mirrors acceptsNewEnrollments
• get_sequence - Get sequence details plus normalized sequence.nodes with each node’s id, nodeType, current config, updatedAt, and updateHints describing editable/managed fields and the concurrency token to return; reusable sequence.edges, graphRevision, and editable sequence.emails are also returned, including each linked email’s effective emailPreset (branded or minimal). sequence.emails covers every email-sending step, including action_ab_test steps - those report nodeType: "action_ab_test" with an abTest summary whose variants[] entries include full blocks when ab_tests:read is granted, and their step-level copy is control variant A only (see editing the content of a sequence A/B step). Send Time Optimization is campaign-only; sequences use sendingWindow (allowed local hours/days), which is a shared gate, not per-subscriber predicted send times
• simulate_sequence - Dry-run a sequence without sending mail or enrolling anyone. Nobody is auto-enrolled on activate. Without a subscriber it reports who currently matches and activation readiness errors. Pass subscriberId or email to walk that stored contact’s branch path, and limit (1-25, default 10) to control the current-match sample. Call this before enable_sequence
• send_sequence_test_email - Send one saved action_email step to 1-10 internal reviewers without enabling the sequence or enrolling subscribers. Pass the sequenceId and nodeId from a get_sequence email entry only when its nodeType is action_email; action_ab_test variants are not supported by this tool and should be inspected on get_sequence.sequence.emails[].abTest.variants. Each result includes a durable emailSendId for get_email_send
• create_sequence - Create a sequence with:
  • Only name for a blank, disabled trigger-to-completion draft matching the dashboard; trigger defaults to contact_added
  • Dashboard metadata (description, labels, userCancellable, and sequence BCC recipients) plus full From/Reply-To identity
  • trigger: "inbound_webhook" with integration metadata, in addition to list, tag, segment, event, inactivity, and frequency triggers
  • trigger: "segment_entered" plus segmentId for saved-segment entry automations
  • trigger: "segment_exited" plus segmentId to enroll active contacts who stop matching a saved segment
  • listIds for a contact_added trigger covering several lists, and tagNames for a tag_added trigger covering several tags - joining or receiving ANY of them enrolls the contact (up to 25 values each). Use these when the user says “when added to list A or list B”
  • listScope for contact_added triggers with no list at all: any_contact (the default) enrolls every contact that is added, including the list-less contacts an integration creates when its list targeting is empty, while any_list waits until the contact joins a list. It cannot be combined with listId/listIds
  • goal - AI generates email content
  • durationDays - total duration used to space AI-generated emails when using goal
  • emailStyle - visual (designed) or plain (text-first) for AI-generated emails; defaults to the company’s saved preference
  • steps with blocks - Sequenzy JSON block format
  • steps with html - Any HTML (React Email, MJML, provider exports, etc.) preserved as one raw HTML block
  • steps with attachments - URL-backed file attachments ([{ filename, path }]) fetched at send time. For event-triggered sequences, path can use an event value such as {{event.file_url}}, and filename can also contain merge tags (max 10 per email, 15MB total)
  • enrollmentMode: "matching_field" for event-triggered product-, variant-, order-, or subscription-specific sequences that should block duplicate active runs only for the same resolved field
  • A scalar enrollmentFieldPath, such as order.id or product.providerVariantId, when you want matching_field to use a custom event property. Array traversal with [] is supported by propertyFilters, not enrollment keys
  • propertyFilters for event_received triggers - only start the sequence when the event properties match, e.g. scope a purchase sequence to one product with { "path": "lineItems[].providerProductId", "operator": "equals", "value": "prod_123" } (or productIds for Stripe saas.purchase events)
  • For event_received sequences, step content can use {{event.amount}}, {{event.order.id}}, or other {{event.*}} merge tags from the event payload that enrolled the subscriber
  • Custom-event responses include eventTrackingCode plus eventTracking, which gives the endpoint, normalized trigger filters, a generated payload example, examplePayloadMatchesFilters, the direct docs URL, and arguments for get_integration_guide. When the example does not satisfy every filter automatically, follow examplePayloadNote and adapt it before sending
• update_sequence - Modify a sequence, target a specific step with the emailId or nodeId returned by get_sequence (email steps only - action_ab_test steps keep their copy on the test’s variants), atomically replace its typed trigger, or update enrollmentMode / enrollmentFieldPath. Set bccEmails to blind-copy team inboxes on every email the sequence sends (use clearBccEmails to remove them). Email steps also accept attachments ([{ filename, path }]) - URL-backed files fetched and attached at send time; path may be an {{event.*}} URL template resolved separately for each enrollment, and [] removes them. Tag, list, wait, condition, and webhook steps added through insertSteps or a branch path carry their node fields in config: action_add_tag / action_remove_tag take tagName (or tagId when you have the real tag ID), action_add_to_list / action_remove_from_list take listId, logic_wait_for_event takes eventName with timeoutDays / timeoutAction, logic_condition takes conditionType plus its resource field, action_webhook takes an HTTPS url with optional method (GET/POST/PUT/PATCH/DELETE), headers, a JSON body template, resultKey (saves the response for later {{webhooks.KEY.data.field}} merge tags), and onError (continue/exit/fail), and action_ai takes a merge-tag prompt, a required resultKey, outputFields with per-field fallbacks whose combined limits fit a 2000-token response budget, and optional includeTags/includeEventProperties/includeRecentEvents (with recentEventLimit, 1-50, default 10)/includeAttributes context selectors so later steps can read {{ai.KEY.field}}; SMS, discount, and delay steps keep using their step-level fields
• update_sequence_node - Patch one existing node in place using its nodeId. It cannot edit the copy of an action_ab_test step, which lives on the test’s variants - read those blocks from get_sequence.sequence.emails[].abTest.variants and change each one with update_ab_test_variant. It supports every stored node type: delays, email/SMS content, actions, conditions, branch configuration without topology changes, webhooks, and triggers. Pass the node’s latest updatedAt as expectedUpdatedAt to prevent stale writes. action_email nodes accept emailTheme to restyle that one step’s linked email - { "emailTheme": { "colors": { "background": "#ffffff" } } } repaints only that email’s background and leaves the account-wide theme and every other email alone. It is a partial patch merged into the email’s current theme (or the company theme when the step has no override yet); null drops the override so the step follows the company theme again, and get_sequence echoes the stored override back as emailTheme
• update_sequence_nodes - Apply multiple type-aware node patches atomically. Use this for bulk edits such as changing every 5-minute delay to 7 days, or restyling several email nodes at once with { "emailPreset": "minimal" } or { "emailTheme": { "colors": { "background": "#ffffff" } } }; either every patch commits or none do
• edit_sequence_graph - Atomically move, reconnect, delete, or deep-copy existing sequence nodes using the latest graphRevision; deleting a step immediately moves parked recipients to its unique surviving successor, or completes them when no successor remains, and returns migratedRecipientCount / completedRecipientCount; active sequences require explicit structural-change confirmation
• insert_sequence_step - Insert a typed email, SMS, delay, discount, subscriber-update, tag/list, outbound webhook, AI, condition, logic_wait_for_event, or logic_branch step. AI steps (type: "ai") accept a merge-tag prompt, a required resultKey, outputFields with per-field fallbacks, and optional context selectors; later steps read the output with {{ai.KEY.field}} merge tags. Webhooks accept an HTTPS URL, a GET/POST/PUT/PATCH/DELETE method, string-valued headers, a JSON body template, a resultKey that saves the response for later {{webhooks.KEY.data.field}} merge tags, and onError failure behavior; URL, headers, and body support merge tags resolved at execution time. Wait nodes accept eventName, timeoutDays, and timeoutAction. Branch paths accept typed conditions plus targetNodeId/elseTargetNodeId, new path steps, or both, so one atomic call can route a reply path to completion and Else to an existing follow-up. Pass splitMode: "random" with randomPercentages to make the branch a weighted A/B split instead, which routes by percentage rather than by condition and has no else path
• enable_sequence / disable_sequence - Control status
• duplicate_sequence - Create an independent draft copy, including graph, emails, and sequence A/B tests
• create_sequence_from_example - Clone a public email gallery sequence into a draft with the example’s trigger and timing (up to 12 emails); AI writes each email in your brand in the background, so poll get_sequence until enrichmentStatus is complete
• archive_sequence / unarchive_sequence - Move a sequence into the dashboard archive or restore it as a draft
• list_sequence_goals / create_sequence_goal / update_sequence_goal / delete_sequence_goal - Manage the persisted event, subscriber-attribute, or tag-applied conversion goals shown by the dashboard
• get_sequence_inbound_webhook / configure_sequence_inbound_webhook / rotate_sequence_inbound_webhook_secret - Read and configure the secret endpoint, field mapping, sample payload, and setup state attached to an inbound-webhook sequence trigger on standard MCP. The OpenAI-reviewed surface removes credential-bearing URLs from read/configure results and omits secret rotation; use the returned sequence dashboard URL there
• enroll_sequence_audience - Estimate (default) or, with dryRun: false, start a background run that enrolls a whole audience ({ type: "all" }, lists, a segment, a filter, or rules) with no per-call cap. Contacts already in the sequence are skipped and unsubscribed or bounced contacts are never enrolled. This is how a manual-trigger countdown sequence gets its audience; late enrollees skip steps whose key date already passed. Poll with get_sequence_audience_enrollment, list runs with list_sequence_audience_enrollments, stop one with cancel_sequence_audience_enrollment.
• enroll_subscribers_in_sequence - Manually enroll up to 500 subscribers by email, subscriber ID, or both. Only active subscribers are enrolled: unknown emails are returned in notFound, and inactive, unavailable, or already enrolled subscribers are counted in skipped. Pass targetNodeId (a non-trigger nodeId from get_sequence) to start at a specific step instead of the first step after the trigger. The sequence must be accepting entrants.
• list_sequence_enrollments - List the individual contacts enrolled in a sequence, with the node each one is sitting on. This is the contact-level view behind get_sequence_stats enrollmentCounts: filter by currentNodeId (IDs come from enrollmentCounts.byCurrentNode or get_sequence), status (defaults to active and waiting), subscriberId, or email. Each row carries email, firstName, lastName, currentNodeLabel, currentNodeType, enrollmentStartedAt, waitUntil (when a waiting contact resumes), failedReason (why a failed enrollment stopped; null otherwise), and movedFromNodeId/movedAt/moveReason (set when move_sequence_enrollments released the contact onto its current step), enteredVia (the list, tag, segment, event, inactivity check, or frequency check that enrolled the contact - the way to tell entrants apart when a trigger covers several lists or tags), entryContext (event id and property keys, never values), and branchDecisions (redacted if/else verdicts with the compared field name and a missing/empty/nonempty/equals_expected summary). Pass status: "failed" to triage a step that is not delivering - failures are terminal, and the same failedReason on one currentNodeId across several contacts points at that step rather than at the contacts. Sort with wait_until_asc to see who moves next, and page with limit (up to 500) and offset until pagination.hasMore is false to export the full list. The response always echoes the sequence’s single configured stopCondition, including any matchConfig event-property filters, field comparison, or entry_audience resolver; entry-audience defaults use value: null and resolve the enrolling tag or list per contact. A stop condition is re-checked when an enrollment next runs a step, not when its event arrives, so a contact whose stop event already landed can keep reporting waiting until its delay expires. Pass stopConditionMatch: true to inspect the current state and read stopConditionMatches per row, where null means “not determined” rather than “does not match”. This is a non-atomic snapshot: a step already past its stop check may still finish. See when a stop condition actually cancels.
• get_sequence_enrollment - Read one enrollment token, including bounded ClickHouse nodeHistory. Use this when a completed token lists as enteredVia unknown or Sequence completed with no email: reconstructed branch decisions are redacted (field name + missing/empty/nonempty/equals_expected), never the raw compared value. Check nodeHistoryTruncated and branchDecisionsTruncated before treating either audit trail as complete. Take enrollmentId from list_sequence_enrollments.
• cancel_sequence_enrollments - Stop active or waiting enrollments in a required sequence. Target cancelAll: true to drain every enrollment (the right move when segment-triggered contacts share no entry field value, and the only way to stop contacts already mid-flight - pausing enrollment just blocks new entrants), subscriberIds for a batch of up to 500, subscriberId for one contact, or entry-event fieldValues. Field-value cancellation can use fieldPath or the sequence’s configured enrollmentFieldPath. Every bulk target defaults to dryRun: true; pass dryRun: false to apply, then repeat the call while the response reports remainingCount above zero.
• move_sequence_enrollments - Release a bounded batch of contacts off one sequence step and onto another, keeping their enrollment. Use this instead of cancel-then-re-enroll when you want the next N contacts waiting on a delay to continue early: cancelling discards the enrollment’s entry event properties, stop-condition snapshots, and start date, and re-enrolling is refused while new enrollment is paused. Requires fromNodeId; targetNodeId defaults to that step’s only next step. limit defaults to 100 and caps at 500, sort defaults to wait_until_asc (longest-waiting first), dailyLimit refuses to release more than that many onto the target step in a rolling 24 hours, and tags marks the released wave with existing tag names (needs subscribers:tag). Defaults to dryRun: true; pass dryRun: false to apply, then repeat while remainingCount is above zero. Moved contacts become active immediately, so the sequence emails them as soon as a worker picks them up.
• realign_sequence_enrollments - Pull waiting enrollments in a required sequence forward to the start of its sending window on the day they are already scheduled for. Run it after changing sendingWindow (or a wait-until-weekday step) on a live sequence: existing waits keep the time their delay produced, so a widened window never reaches contacts already parked on an email-bound delay step and a narrowed one defers them to the next allowed day. Sequence windows never advance SMS, webhooks, branches, or other non-email actions. A wait only ever moves earlier, never onto a different local day, and never before now; nobody is cancelled or re-enrolled. Narrow it with nodeIds or subscriberIds. Defaults to dryRun: true; pass dryRun: false to queue an applied job.
• get_sequence_enrollment_realignment - Poll the jobId returned by an applied realign_sequence_enrollments call. When status is completed, inspect result; if result.hasMore is true, queue the next bounded apply with result.nextCursor as cursor.

Branches inside a branch path

1. Insert the outer branch. End each path with the step the nested branch should follow, such as the wait before the flow re-evaluates the contact. Every path’s last step automatically connects to whatever already followed afterNodeId, so the shared steps after the branch exist only once.
2. Read addedBranchPathNodeIds from the response. It maps each branch ID to that path’s new node IDs, in order, so no extra get_sequence call is needed.
3. For each path that needs to re-evaluate, insert a second logic_branch with afterNodeId set to that path’s last node ID. Its own paths reconnect to the same shared step downstream.

​

Transactional

• list_transactional_emails - Search and filter transactional templates by name, slug, subject/title, or active state; sort by delivery metrics; and return each template’s dashboard URL
• get_transactional_email - Read a transactional email by ID or slug, including body blocks
• create_transactional_email - Create a transactional template from a prompt, raw HTML, or Sequenzy blocks. Prompt-generated templates include company branding with no unsubscribe link
• update_transactional_email - Update transactional email metadata or body content
• delete_transactional_email - Permanently delete a saved transactional template by ID or slug, freeing the slug for reuse. Past deliveries and their stats are kept, and the linked email content stays as a reusable template returned as deleted.emailId, which delete_template can remove separately. To stop sends without losing the template, set enabled to false with update_transactional_email instead
• send_email - Send one email using direct subject and html content (mapped to the transactional API’s subject and body fields), or pass a saved transactional email API slug through the compatibility-named templateId field. to, cc, and bcc each accept a single address or an array of up to 50, so a transactional send delivers one email with a shared recipient list rather than one email per address. Addresses repeated across the fields are dropped from the lower-priority one (to beats cc beats bcc), and the result echoes the accepted lists. Marketing sends still take exactly one to address and reject cc and bcc, because suppression and one-click unsubscribe apply per subscriber. Its variables object supports nested arrays for repeat blocks, such as { "event": { "items": [...] } }. Attachments accept Base64 content or a public path (up to 10 files / 15MB total); set contentId to embed a CID image referenced from the HTML and contentType to override MIME detection. When a single recipient matches a subscriber, saved first and last names fill omitted name variables; explicit variables values take precedence. The result echoes the accepted emailType. Optional fromEmail/fromName and replyTo/replyToName pick an existing verified brand identity for that one send without profile IDs; they do not create profiles. fromEmail looks up a send-ready sender by address, and if several identities share the address pass fromName (or senderProfileId from list_sender_profiles). senderProfileId/replyProfileId remain available when you already have them. When those fields are omitted, a template send keeps its saved From and Reply-To identities, while a direct send uses the company defaults. replyTo remains a one-off Reply-To string and is mutually exclusive with replyProfileId. {{viewInBrowserUrl}} becomes a hosted copy link. When trackingSettings is omitted, the account’s Transactional API tracking defaults apply. Set clickTracking or openTracking to false to opt out for that send only; these fields cannot enable tracking disabled by the account defaults. The optional headers object adds extra email headers, such as your own List-Unsubscribe on a transactional send; marketing sends keep Sequenzy’s signed unsubscribe headers, and headers Sequenzy manages are never applied. Header values must be strings. Headers the API does not apply are listed in the result’s ignoredHeaders with a reason instead of failing the send.
• get_transactional_stats - Inspect top clicked links, complaints, replies, bounce classifications, and separate human/machine engagement for one saved template
• list_email_sends - Search recent delivery history and return a dashboard URL on every delivery; every row carries subscriberId, automationNodeId, and abTestVariantId, and a returned ID with get_email_send gives the full timeline

​

Segments

• list_segments - List saved segments
• create_segment - Create a segment from explicit filters, including nested AND/OR groups, event filters, segment filters, Stripe product purchase filters, and optional filterJoinOperator
• update_segment - Update a segment’s name and/or replace its filter rules using the same filters plus filterJoinOperator or nested root shapes as create_segment
• delete_segment - Permanently delete a segment; subscribers are not affected
• get_segment_count - Preview how many active subscribers match a segment

• {"id":"filter-1","field":"stripeTrialProduct","operator":"gte","value":"prod_pro:start_at:7 days ago"} for “trial started in the last 7 days”
• {"id":"filter-1","field":"stripeTrialProduct","operator":"is","value":"prod_pro:end_at:2026-05-26"} for “trial ends on May 26, 2026”

• {"id":"filter-1","field":"commerceProduct","operator":"is","value":"api:prod-starter-kit"} for “bought product”
• {"id":"filter-1","field":"commerceProduct","operator":"is_not","value":"api:prod-starter-kit"} for “didn’t buy product”

• update_audience_sync - Change the frequency (hourly, daily, weekly) or pause/resume via isActive
• delete_audience_sync - Remove a sync; the Meta audience itself is kept
• sync_audience_now - Trigger an immediate upload outside the schedule

​

• list_warehouse_connections - List connections with status and number of syncs
• create_warehouse_connection - Connect a warehouse with a read-only user; a test query runs before saving
• update_warehouse_connection - Rename, change settings or rotate credentials (re-tested)
• delete_warehouse_connection - Delete a connection that has no syncs

• run_data_export - Export now instead of waiting for the schedule
• list_data_export_runs - Recent runs with rows, files, bytes and errors

​

Products & Digital Delivery

• list_products - List synced products (Stripe, Shopify, WooCommerce, api) including any attached delivery file. Returns one page; supports limit and offset, and reports pagination.total and pagination.hasMore so you can tell a truncated page from the full catalog
• upsert_products - Create or update products in the catalog (Commerce API, keyed by your productId, up to 100 per call)
• delete_product - Delete a product previously pushed via upsert_products
• attach_product_file - Attach a distributable file to a product, delivered after purchase. Pass url for a hosted file, or filePath to upload a local file (local MCP server only)

• sync_products - Queue a sync of the Stripe product catalog

​

Image Assets

• upload_image_asset - Upload a PNG, JPEG, GIF, or WebP image (up to 10MB) to the selected company’s shared media library. The tool returns the hosted asset.url and a complete imageBlock that can be inserted into campaign, sequence, saved-template, or transactional-email blocks.

  "cropHeight": 320,
  "objectFit": "cover",
  "align": "center"
}

​

Tags

• list_tags - List all tags in the account
• create_tag - Create a tag definition. Names are normalized to lowercase with hyphens (VIP Customer becomes vip-customer); color defaults to gray
• update_tag - Update a tag’s color; system tags cannot be changed
• delete_tag - Permanently delete a tag and remove it from all subscribers; system tags and tags used by sequences cannot be deleted

​

Templates

• list_templates - List email templates newest first, with localization status by locale. Pass isTemplate: true to list only reusable master designs. Templates are the company’s saved email bodies - standalone templates plus the bodies behind campaigns and transactional emails - so dashboard-designed emails appear here, and a campaign’s emailId points at its entry. Returns 50 per call by default (limit accepts up to 100); page with offset while pagination.hasMore is true, and read pagination.total for the full count
• get_template - Get a template’s details, content, and localized variants. isTemplate is true for reusable master designs
• create_template - Create a template from a prompt, raw HTML, or Sequenzy blocks. Pass isTemplate: true to save it as a reusable master design that sequence steps and campaigns start from (always as an independent copy)
• create_template_from_example - Remix a public email gallery email into a new template: the example’s exact layout with the text rewritten for your brand and your logo, color and links swapped in, without naming the example brand
• update_template - Update template metadata, inbox preview text, raw HTML, Sequenzy blocks, labels, or the isTemplate mark
• set_template_localization - Create or replace a caller-supplied localized variant. Pass keepEdits: true to protect it like a dashboard edit: automatic on-save translation then keeps it and marks it stale when the original changes
• sync_template_localizations - Queue AI translation for selected or all enabled non-primary locales. Pass skipEdited: true to keep edited variants; they come back in skippedLocales
• share_template - Create (or fetch) the public “view in browser” link for an individual email - a transactional email (by ID or slug), a sequence email (by the step’s emailId), or a standalone template. The hosted page renders an anonymized copy - sample contact, inert unsubscribe link, no open/click tracking. Idempotent: an already-active link is returned with created: false. get_template reports the current link as shareUrl. Campaign links follow the A/B winning variant, so share campaigns with share_campaign instead
• unshare_template - Revoke the public link; the shared URL returns 404 immediately, and sharing again later mints a different URL

​

Email Blocks

• get_email_block_schema - Required and optional fields for each block type, the allowed values of every enum field, and the shape of nested item arrays and nested objects. Omit blockType to list every type; pass one for its full reference plus a minimal valid example and authoring notes. Pass creatableOnly: true to hide structural types such as group that the editor manages. conditionFields, the per-field table for block conditions - which operators each condition field accepts, how its value is shaped, and what a preview needs to evaluate it - comes back when you list every type and when you ask for conditional-group; on any other single type pass conditionFields: true, since the table is several times the size of one block’s reference

​

Email Components

• get_default_email_component - Read the company’s default component for a slot. Call this before changing the footer, then edit the blocks it returns
• set_default_email_component - Create or replace the default component for a slot. Replaces the whole component, so read it first when you only mean to change part of it
• list_email_components - List reusable components newest first; pass defaultsOnly to see only the pinned defaults
• get_email_component - Get one component’s blocks, version, and default-slot status
• create_email_component - Save a block group as a reusable component. Names are unique per company
• update_email_component - Update metadata or replace blocks. Replacing blocks bumps the component version
• delete_email_component - Delete a component. Emails that already use it keep their copied blocks

​

A/B Tests

• list_ab_tests - List A/B tests and variants, optionally scoped by sequence
• get_ab_test - Get effective settings, variants, content, and localization status. Copy the returned settings object; sequence testPercentage: 100 and testDurationMinutes: 0 values are legacy sentinels
• get_ab_test_stats - Get aggregate and per-variant stats, plus significance: whether the leading variant’s advantage on the winning metric is statistically significant at 95% confidence
• select_ab_test_winner - Select a campaign test winner and queue the winning variant for the remaining audience, which starts external email delivery. On a sequence test, select or change the winner, including one picked automatically, for everyone who reaches the step afterwards; sequence tests need sequences:write instead of campaigns:send, and confirmLiveChange: true while the sequence is active
• resume_ab_test - Clear a sequence test’s winner so contacts are split across the variants again, keeping the results so far. The test then waits for select_ab_test_winner instead of picking automatically; update_ab_test with autoSelectWinner: true turns automatic selection back on. Pass confirmLiveChange: true while the sequence is active
• create_ab_test - Provide exactly one of campaignId or automationNodeId. Campaign tests use testPercentage, testDurationMinutes, and winnerCriteria; a sequence email node is converted to action_ab_test with testType, winnerThreshold, and winnerCriteria. An explicit sequence winnerCriteria overrides the test-type default. Pass confirmLiveChange: true when converting a node in an active sequence. Control variant A is created automatically
• update_ab_test - Update campaign or sequence settings. Campaign tests accept percentage/duration/criteria; sequence tests accept type/threshold/criteria and require confirmLiveChange: true for active or already-used tests
• add_ab_test_variant - Add a variant to a draft campaign or sequence A/B test; sequence variants receive independent email templates
• update_ab_test_variant - Update a variant’s subject, preview text, HTML, or blocks. Campaign variants are editable in draft only; sequence variants stay editable, with confirmLiveChange: true once the sequence is active or the test has activity
• delete_ab_test_variant - Permanently remove a variant from a draft campaign or sequence A/B test; variant A is the control and cannot be deleted
• delete_ab_test - Permanently delete a campaign A/B test and all of its variants; running tests cannot be deleted

​

Editing the content of a sequence A/B step

• get_sequence still lists the step in sequence.emails with nodeType: "action_ab_test", but its subject, previewText, and blocks are control variant A only. With ab_tests:read, the step’s abTest object carries the test id, status, and one entry per variant including that variant’s full blocks, plus a contentEditing pointer at the tools below. Without that scope, test-record fields are redacted and variants is empty while the configured id and editing guidance remain available.
• update_sequence_node cannot change variant content. It still edits the step’s identity fields (label, sender and reply profile, cc/bcc, transactional flag), and rejects blocks/subject/previewText with a pointer at update_ab_test_variant.
• A change that should apply to the whole step has to be repeated on every variant - otherwise you are changing what the test measures.
• Never rebuild an action_ab_test step as a plain email node to reach its content. That destroys the test and its results.

get_sequence          -> step.nodeType === "action_ab_test", step.abTest.variants[].blocks
update_ab_test_variant -> apply the change, once per variant

​

Team

• list_team_members - List the company owner, members with their roles, and pending or expired invitations
• invite_team_member - Invite a teammate as admin, marketer, viewer, or restricted. Marketers create, edit, and send campaigns and sequences and manage subscribers but cannot access transactional emails, settings, billing, or the team. Existing Sequenzy users are added immediately; everyone else receives an email invitation. Billing access (canManageBilling) can only be granted by the company owner and is not available for marketer or restricted members
• cancel_team_invitation - Cancel a pending invitation; accepted invitations cannot be cancelled

​

Inbox

• list_conversations - List subscriber reply conversations with status, search, unread, and pagination filters
• get_conversation - Get a conversation with its full message history, subscriber details, and context
• reply_to_conversation - Send an outbound reply (requires bodyText or bodyHtml) or add an internal team-only note with type: "note". Pass senderProfileId (from list_sender_profiles) to reply from a specific verified sender. Replying to a closed conversation reopens it
• update_conversation_status - Open or close a conversation
• bulk_update_conversation_status - Open or close up to 100 conversations in one call with conversationIds and status. Returns updatedIds, unchangedIds (already had the status) and notFoundIds; retrying is safe because only conversations whose status changes are updated
• mark_conversation_read - Mark all unread inbound messages in a conversation as read

​

Webhooks

• list_webhooks - List outbound webhook endpoints and their subscribed event types
• create_webhook - Create an endpoint and return its one-time signing secret on the standard MCP surface. It is omitted from the OpenAI-reviewed surface; create it in the dashboard or local CLI there
• update_webhook - Update a webhook’s name, URL, subscribed events, or enabled/disabled status; providing events replaces the existing list
• delete_webhook - Permanently delete a webhook endpoint and stop all deliveries to it
• test_webhook - Send a test event to verify the endpoint is reachable and signatures validate
• list_webhook_deliveries - List recent delivery attempts, including status and response codes
• replay_webhook_delivery - Re-send a previous delivery’s event payload to the endpoint

​

Analytics

• get_stats - Overview stats (7d/30d/90d). Counts are a funnel over the sends made inside the period: opened and clicked are unique per email send (not total open events) and include engagement that arrives after the period ends, so they never exceed sent. Rates divide by rateDenominator (delivered, falling back to sent), returned with rateDenominatorBasis. Also returns top-level subscriberCount (every stored contact) and activeSubscriberCount (status=active) as a live audience snapshot, independent of period. Set emailType to transactional for Send API and transactional SMTP open/click rates, including direct and saved-template sends
• get_transactional_stats - Aggregate metrics for one saved transactional email by ID or slug, all-time or within a requested period/range
• list_email_metrics - One row per email across the account: each campaign and each sequence email step, with its own funnel, attributed conversions, and revenueCents. This is the cross-sequence tool: “how many step-4 emails went out across these sequences” is one call with step: 4 plus the returned totals, not one get_sequence_stats per sequence. Sequence rows carry sequenceId, sequenceName, automationNodeId, and step. Filter by emailType, sequenceId, campaignId, and step; sort with sort/order; page with page/limit. totals covers every matching email, not just the returned page. Counts come from retained event storage, so unlike list_email_sends they are not limited to 14 days; omit period/start/end for all-time counts
• list_email_sends - Search and filter the recent dashboard delivery history by subject/title, recipient, status, type, or source ID, including automationNodeId to list the recipients of one sequence step. Each row carries recipientEmail, subscriberId, automationNodeId, abTestVariantId, and the sent/delivered/opened/clicked timestamps, so rows join into a recipient-level delivery matrix without re-reading the raw event stream. Rows are retained for 14 days, so use get_sequence_stats steps[] or list_email_metrics for send totals
• get_email_send - Inspect one delivery’s status, timestamps, failure details, stored HTML, and event timeline. Failed test sends appear here too, flagged isTestEmail: true - a test send is queued rather than delivered inline, so this is where you find out one never arrived
• list_recipient_suppressions - Every associated recipient the workspace currently cannot reach, newest first, with a stable suppressionType, the reason, the scope (global blocks every workspace, company only this one), and whether the entry can be removed. Global invalid-recipient rows, company hard bounces without conclusive invalid-inbox evidence, and complaints are protected; company soft-bounce escalations are removable. Start here for “why didn’t this person get my email?”: this is the standing list of who is blocked, whereas list_email_sends shows individual attempts (a suppressed send does get a row there, with status suppressed). Filter with search, page with page/limit, and order with sort (suppressedAt, email, status) plus order (asc/desc) - sort=status surfaces the removable escalations first, and the response echoes the sortBy/sortOrder actually applied
• get_recipient_suppression - Full suppression check for one exact address, including the regional Amazon SES account-level list
• remove_recipient_suppression - Clear a company-scoped soft-bounce escalation for one associated address and reactivate the matching bounced subscriber. Global invalid-recipient and Amazon SES account-level suppressions, spam complaints, and unsubscribes are protected
• get_campaign_stats - Campaign performance, plus a top-level clickedLinks array with the per-link click breakdown, a top-level goals array when conversion goals are attached to the campaign, and a top-level polls array with answer distributions and NPS score/breakdown when the campaign collected survey responses
• get_email_client_stats - Mail client (Apple Mail, Gmail, Outlook, …) and device shares of unique opens, for one campaign with campaignId or company-wide for a period
• list_poll_responses - Individual Poll and NPS responses for a campaign: each respondent’s email, their answer and stored value, the attribute the answer was saved to, and the response time, newest first. Scope to one block with blockId. Only each subscriber’s latest answer per block is returned, so counts match get_campaign_stats. Use this instead of scanning subscribers for the poll attribute - the attribute carries no response time and reflects the latest answer to any email
• get_sequence_stats - Sequence performance, including a steps array with each email step’s own sent/delivered/opened/clicked/replies counts, node ID, and subject - read that instead of counting list_sequence_events. Also returns live active/waiting enrollment-run counts grouped by current node; historical date filters do not limit the live counts. Use list_sequence_enrollments to get the actual contacts behind those counts, and list_email_metrics to compare the same step across sequences
• list_sequence_events - Paginated raw per-recipient events for a sequence’s email steps, or one step via automationNodeId. Use it to see who received or engaged with a step, not to count sends
• get_subscriber_activity - Individual activity

​

AI Generation

• generate_email - Create email blocks from a prompt. Company logo/footer branding is included by default; use applyBranding: false for raw content blocks, or emailType: "transactional" for a footer without an unsubscribe link
• generate_sequence - Deprecated compatibility alias for goal-based create_sequence; it persists the same disabled draft
• generate_subject_lines - Generate A/B subject variants
• generate_sms - Generate SMS message variants with encoding and segment counts

​

SMS

• get_sms_settings - SMS add-on status: enabled, plan eligibility, credit balance, brand prefix, numbers, and a readyToSend flag that accepts either a paid plan or SMS credits plus an active number
• update_sms_number_label - Update an SMS number’s label and/or its brand prefix override
• get_sms_usage - Per-number usage: sends, delivered, failed, credits charged, last sent, and test-send counts
• send_test_sms - Send a real test text (charges credits, max 100 per company per rolling 24 hours, bypasses quiet hours); optionally pick which active number it sends from
• release_sms_number - Release a toll-free number back to the carrier and free its slot under the workspace’s 100-number cap. IMPORTANT: this is irreversible - only call it when the user explicitly asks to remove or release a number

​

Push Notifications

• get_push_settings - Web push, APNs and Firebase readiness, last credential errors, and active device counts per platform
• update_web_push_settings - Turn web push on or off (the first enable generates VAPID keys) or set the default notification icon
• set_apns_credentials / remove_apns_credentials - Save or remove the APNs auth key (.p8) for iOS push
• set_fcm_credentials / remove_fcm_credentials - Save or remove the Firebase service account for Android push
• list_push_devices / register_push_device / remove_push_device - Manage registered browsers and app installs; tokens are never returned in full
• send_test_push - Send a real test push to one device or a contact’s devices (max 200 per company per rolling 24 hours, excluded from stats)
• list_push_campaigns, get_push_campaign, create_push_campaign, update_push_campaign, duplicate_push_campaign - Manage push campaign drafts
• estimate_push_campaign_recipients - Count audience contacts with an active device
• send_push_campaign, unschedule_push_campaign, cancel_push_campaign - Send, schedule, unschedule, or stop a push campaign. Confirm with the user before sending
• get_push_campaign_stats - Sent, displayed, clicked, failed and skipped counts with reasons

​

Feedback

• submit_feedback - Send product feedback about Sequenzy to the Sequenzy team

​

Interactive email and sequence previews

• render_email opens the rendered email with Desktop (640px) and Mobile (375px) views, its subject, preview text and personalization warnings. Pass a campaign ID, template ID, or sequence ID plus node ID using the existing tool inputs. It renders your saved content through Sequenzy’s email renderer. Personalization and locale options remain available through the same tool.
• preview_sequence({ companyId, sequenceId }) opens the saved sequence as a connected diagram with triggers, delays, branches and actions. Select an email to render it, switch between available A/B variants, or use the Emails tab to browse the sequence’s emails. Random splits show their configured allocation. Refresh reloads saved content, and failed requests offer an explicit retry.

• open_image_upload({ companyId }) opens an image picker. Choose a PNG, JPEG, GIF or WebP up to 10 MB, optionally describe it, then select Upload image. Opening the widget does not write anything. Submission uses upload_image_asset with your existing permissions and returns the saved asset to your assistant. After an uncertain failure, check your image library before retrying; uploads are never automatically retried.
• monitor_subscriber_import({ companyId, importId }) shows counts and progress for an existing import. It polls get_subscriber_import every five seconds while running, for up to five minutes. Completion, blocked status, errors or leaving the view stop polling. Refresh status restarts monitoring. This does not start or retry imports.

​

Set up email for a new SaaS

You: "Set up email sequences for my SaaS that has a 14-day trial"

Claude: I'll help set that up. First, let me check your current sequences...
[Uses list_sequences]

You don't have any sequences yet. I'll create three for you:
1. Welcome sequence (triggered on signup)
2. Trial nurture (days 1, 3, 7, 10, 13)
3. Trial ending reminder (day 12)

[Uses create_sequence for each]

Done! I've created 3 sequences with 8 emails total.

​

Add a subscriber

You: "Add john@example.com as a VIP subscriber"

Claude: [Uses add_subscriber]
Added john@example.com with the VIP tag.

​

Publish a landing page

You: "Create a landing page for our product waitlist and publish it"

Claude: [Uses create_landing_page with template "waitlist", then publish_landing_page]
Done. I created and published the waitlist page. The public URL is ready, and I can connect pages.example.com if you want a branded domain.

​

Create a Stripe product segment

You: "Create a segment for subscribers who bought Stripe product prod_pro at least 3 times"

Claude: [Uses create_segment with filters:
{"id":"filter-1","field":"stripeProduct","operator":"at_least","value":"prod_pro:3"}]
Done. I created the segment and saved it for future campaigns.

​

Create a match-any segment

You: "Create a segment for VIP contacts or anyone on Gmail"

Claude: [Uses create_segment with:
{"filterJoinOperator":"or","filters":[{"id":"filter-1","field":"tag","operator":"contains","value":"vip"},{"id":"filter-2","field":"email","operator":"contains","value":"@gmail.com"}]}]
Done. I created a segment that matches either condition.

​

Check performance

You: "How did my last campaign perform?"

Claude: [Uses list_campaigns then get_campaign_stats]
Your "Product Launch" campaign sent yesterday had:
- 2,451 sent
- 67.2% open rate
- 12.3% click rate
That's above your average!

​

Create a sequence with specific content

You: "Create a 3-email welcome sequence with specific content.
Email 1 (immediate): Subject 'Welcome!' - 'Thanks for joining us.'
Email 2 (1 day later): Subject 'Getting Started' - 'Here's how to begin.'
Email 3 (3 days later): Subject 'Pro Tips' - 'Unlock advanced features.'"

Claude: [Uses create_sequence with steps]
Done! I've created the welcome sequence with 3 emails:
1. "Welcome!" - sends immediately
2. "Getting Started" - sends after 1 day
3. "Pro Tips" - sends after 3 days

The sequence is in draft mode. Would you like me to enable it?

​

Migrate a sequence from another platform

You: "I have these React Email templates for my onboarding sequence.
Can you create a sequence that sends them?"

[Pastes HTML content]

Claude: [Uses create_sequence with steps using html field]
Done! I've created your onboarding sequence with the HTML content
you provided. The HTML was automatically converted to Sequenzy's
block format so you can edit it in the visual editor later.

The sequence is ready in draft mode with 3 emails.
