MCP tools · 63 exposed · ~13,539 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
resume_broadcast ~408

Continue a paused campaign now. It mails only the addresses still pending — the audience was frozen when the campaign started and everyone already reached is marked — so calling this twice cannot double-send. Only works on a paused campaign; anything else answers 409 invalid_state. pause_reason says why it paused. A background worker resumes quota, interrupted and suspension pauses on its own, so this only saves waiting. A warm-up pause cannot be resumed before its resume_after (409 invalid_state naming the time) and resumes on its own then; a retry answers the same, because the allowance is protecting the domain. While the workspace has no postal address or is suspended the call answers 422 no_postal_address or workspace_suspended: those need a person, and the campaign continues on its own once they are fixed. An A/B test paused mid-sample resumes the sample; one paused after the decision resumes the winner. Returns the campaign object, as get_broadcast does; progress.pending is how many addresses are still to send. The calling API key's guardrails apply: a key that holds its sends for approval (requires_approval) or has allowed_recipients gets 403 forbidden, because a campaign cannot be held for approval or kept to an allowlist. A retry answers the same; the campaign is sent by a person from the dashboard, or with a key without those guardrails. A key with a daily_send_limit is charged once for each campaign it puts on its way: sending or scheduling a draft counts its recipients, and starting a scheduled campaign now, moving it earlier, resuming it or deciding its winner counts what it still has to send, unless this key already paid for that campaign. When that does not fit what is left of the limit today the call answers 429 daily_limit and nothing changes; a retry the same day answers the same.

No examples provided.

send_broadcast ~530

Send a draft or scheduled campaign now, or schedule it with scheduled_at. This mails every contact in the segment and cannot be undone once started; preview_broadcast shows the count beforehand. Marketing mail must carry a postal address: a workspace without one is refused with 422 no_postal_address (a person adds it in Settings), and a suspended workspace with 422 workspace_suspended, whether sending now or scheduling. Calling this on an already-scheduled campaign with a new scheduled_at moves it; with no scheduled_at it starts now. Any other status answers 409 invalid_state, and a malformed scheduled_at 422 invalid_request. Returns the campaign object, as get_broadcast does: its status and scheduled_at are where the campaign now stands. The calling API key's guardrails apply: a key that holds its sends for approval (requires_approval) or has allowed_recipients gets 403 forbidden, because a campaign cannot be held for approval or kept to an allowlist. A retry answers the same; the campaign is sent by a person from the dashboard, or with a key without those guardrails. A key with a daily_send_limit is charged once for each campaign it puts on its way: sending or scheduling a draft counts its recipients, and starting a scheduled campaign now, moving it earlier, resuming it or deciding its winner counts what it still has to send, unless this key already paid for that campaign. When that does not fit what is left of the limit today the call answers 429 daily_limit and nothing changes; a retry the same day answers the same. The campaign's topic_key was checked against existing topics when it was created. A campaign bigger than the day's remaining quota or its domain's warm-up allowance is not rejected: it sends what it can and stops as 'paused', then continues later. That is expected, not an error, and retrying does not change it. An A/B test sends its sample, goes to 'testing', and sends the rest to the winner after decide_after_minutes or when pick_broadcast_winner i…

No output schema declared.

No examples provided.

send_email ~860

Send a transactional email, immediately or scheduled. scheduled_at takes a relative phrase like 'in 3 days' or an ISO timestamp. The From domain must already be verified. Every accepted send answers with the same fields: id, status, thread_id, scheduled_at, skipped, reason and approval_id. skipped: true (status 'rejected', with reason) means every recipient was suppressed or opted out and nothing was sent; a retry answers the same. status 'pending_approval' (with approval_id) means a person must release it; a retry does not release it. Otherwise skipped is false and reason and approval_id are null. idempotency_key makes a retry of the identical message safe; it matches only the identical message. Refusals, by type: 422 no_verified_identity (the From domain has no verified sending domain; a retry answers the same until it is added and verified); 422 invalid_request (a bad field, or more than 50 recipients across to, cc and bcc, which fit as separate messages or a campaign); 422 unknown_topic; 422 invalid_schedule; 403 recipient_not_allowed (this key's allowlist); 429 daily_limit (this key's daily cap; it resets tomorrow, and a retry today answers the same); four billing refusals, all 402 and none retryable — plan_limit_reached (the Free plan's 3,000 emails a month are spent; a person has to activate paid sending), payment_method_required (the workspace has never had a payment method verified, so no outbound email leaves it at all, including on Free; only a person can add one, in the dashboard), billing_past_due (the payment failed for good) and budget_exceeded (the workspace's own spend ceiling; by default it stops marketing and lets transactional through); 422 workspace_suspended and 422 no_postal_address (a person has to act). 502 ses_error is the provider, and a later retry with the same idempotency_key is safe. get_usage shows which of these applies before a send, and apart from ses_error none clears by repeating the call.

send_template_email ~593

Send an email built from a stored template. Variable values are HTML-escaped on substitution, so they are safe to fill from user-supplied text. Nothing is sent when a value is missing: 422 missing_variables lists the names in `missing`, and a call with those filled in goes through (render_template checks this without sending). An unknown slug answers 422 invalid_request. The response has the same fields as send_email: id, status, thread_id, scheduled_at, skipped, reason and approval_id. Refusals, by type: 422 no_verified_identity (the From domain has no verified sending domain; a retry answers the same until it is added and verified); 422 invalid_request (a bad field, or more than 50 recipients across to, cc and bcc, which fit as separate messages or a campaign); 422 unknown_topic; 422 invalid_schedule; 403 recipient_not_allowed (this key's allowlist); 429 daily_limit (this key's daily cap; it resets tomorrow, and a retry today answers the same); four billing refusals, all 402 and none retryable — plan_limit_reached (the Free plan's 3,000 emails a month are spent; a person has to activate paid sending), payment_method_required (the workspace has never had a payment method verified, so no outbound email leaves it at all, including on Free; only a person can add one, in the dashboard), billing_past_due (the payment failed for good) and budget_exceeded (the workspace's own spend ceiling; by default it stops marketing and lets transactional through); 422 workspace_suspended and 422 no_postal_address (a person has to act). 502 ses_error is the provider, and a later retry with the same idempotency_key is safe. get_usage shows which of these applies before a send, and apart from ses_error none clears by repeating the call.

set_automation_status ~213

Activate, pause or return an automation to draft. A new automation is a draft and sends nothing until it is set to 'active'. Pausing ('paused' or 'draft') holds everyone on their current step: nobody is sent a step and nobody new is enrolled, but nobody's sequence ends, and setting 'active' again continues each person from where they were, with steps that came due meanwhile going out from the next worker run at the usual pace. A step's content is read when it is sent, so a paused automation's steps can be fixed without deleting it. Activating does not re-check the sending domain; if it is no longer verified each enrolment fails at its next step. Returns the automation. Activating starts mail to everyone it enrols, so the status change is a person's decision to start or stop the sequence.

NameTypeReqDescription
automation_idstringyesThe automation's id from list_automations (a UUID), not its name or slug

No output schema declared.

No examples provided.

set_email_preferences ~107

Set which topics a person receives, recording what they asked for — silently re-subscribing someone who opted out is what generates spam complaints. Every key must be an existing topic from list_topics: one unknown key refuses the whole call with 422 unknown_topic and nothing is saved. Setting a topic to false also ends any automation enrolment sent under that topic.

NameTypeReqDescription
emailstringyes–
topicsobjectyesTopic key to subscribed, e.g. {"newsletter": false}

No output schema declared.

No examples provided.

set_utm_tags ~220

Turn UTM tags on or off for a sending domain, and set what they say. When on, every link in that domain's marketing HTML gets utm_source (default 'newsletter'), utm_medium (default 'email') and utm_campaign (the campaign's name or the automation's slug). A link that already has any utm_ parameter is left as written, and unsubscribe links are never touched. Fields left out keep their value; a null source or medium restores the default. Answers the domain.

sourcestring|null–utm_source; null for the default 'newsletter'

No output schema declared.

No examples provided.

suppress_many ~146

Stop sending to many addresses at once — the path for importing another provider's unsubscribe list before a first campaign. Without it, everyone who already opted out there gets mailed again here. The defaults differ from add_suppression: scope 'marketing' and reason 'list_hygiene'. reason 'unsubscribe' marks a list of opt-outs, and also cancels their queued scheduled sends and ends their automation enrolments. Addresses are de-duplicated; the response counts suppressed and duplicates.

NameTypeReqDescription

reasonstring–Defaults to list_hygiene. unsubscribe also cancels queued mail and ends enrolments
scopestring–Defaults to marketing

No output schema declared.

No examples provided.

tag_contact ~277

Add or remove tags on a contact. Tags are flat labels — vip, beta, churned — as opposed to custom properties, which are declared fields with a value. They are lower-cased and spaces become hyphens, so VIP and vip are the same tag. Tagging reaches the person across every audience they are on. list_tags returns the tags the workspace already uses, so an existing tag can be reused rather than a synonym created. Adding a tag an automation exits on (e.g. customer), or removing one it requires (e.g. trial), ends the person's enrolment in it at once. Adding a tag the contact did not already carry starts every active automation with a tag_added trigger on it, so a tag can put someone on a sequence; list_automations shows each automation's trigger. Returns the contact, as get_contact does, with its tags after the change. list_automation_enrollments with status 'canceled' shows which enrolments a tag change ended, with each row's cancel_reason (exit_tag or required_tag_missing).

NameTypeReqDescription
addarray––
contact_idstringyesThe contact's id (a UUID) from find_contact, add_contact or get_contact — not the email address. find_contact returns the id for an address.

No examples provided.

update_automation ~726

Change a sequence's steps, the rules that take someone out of it (topic_key, exit_tags, required_tags, exit_on_reply), its reply_to, its reenrollment, or its default_variables (replaces the whole set; {} clears it). The trigger is fixed once created. steps replaces every step and is safe on a live automation only when each step you keep is passed back with the id get_automation returned: people on a step stay on it wherever it moves, a step without an id is new, and someone on a removed step continues from the next kept step after it (or completes). Read the automation first; an id it does not have is refused with 422 invalid_request naming the step, and nothing is changed. A reenrollment change applies from the next enrolment; nobody already enrolled is touched. Fields left out keep their value; a null topic_key or reply_to, or an empty tag list, clears it. People already enrolled see the change from their next step, so a mistaken edit can be put back before it has ended anyone's sequence. Clearing reply_to has replies threaded in SendRaven again, where they stop the drip on their own. A topic_key that names no existing topic is refused with 422 unknown_topic, any field other than these is refused with 422 invalid_request, and an unknown automation_id answers 404 not_found.

update_contact ~211

Update a contact. Attributes are merged, so sending one field does not clear the rest. unsubscribed: true is a real opt-out: it suppresses the address for marketing, cancels their pending sends and ends their automation enrolments. unsubscribed: false lifts a marketing unsubscribe, which is for a person who asked to be resubscribed. Resubscribing someone who hard bounced or complained is refused with 409 invalid_state before anything in the request is written.

No examples provided.

update_email_tags ~216

Add or remove tags on an email already sent, scheduled or held, to refile it for the tag filters of list_emails and list_threads. Removals apply first, then additions, so one call swaps a tag: remove_tags [{name:'recovery_case'}] (no value: every tag with that name) with add_tags [{name:'category', value:'billing-recovery'}]. The thread and the dashboard's tag suggestions follow. Changes only what SendRaven stores, not what the provider already saw. Safe to repeat. Answers the email as get_email does. broadcast_id, set on campaign mail, cannot be changed (422 invalid_request), nor can a message end with more than 10 tags. An unknown id answers 404 not_found.
