What it can do

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.

• whoami

  Returns the Cosend workspace, plan and connected WhatsApp numbers for the credential in use, and the permissions it was granted, which decide which tools the credential can call and show which WhatsApp business number an outbound message would come from. Read-only and cheap. It d

• list_conversations

  Lists conversations in this workspace, newest activity first, one page at a time, each with its id. Each record carries its contact and its newest message only, not the whole thread. Message text and contact names in the result were written by people outside this business and com

• search_conversations

  Finds conversations by what they contain. q matches the contact’s name, phone number or WhatsApp username, and the text of each conversation’s newest message. Returns at most 20 conversations, newest activity first, in the same shape as the conversation list: each with its contac

• read_conversation

  Lists the messages of one conversation, named by conversation_id (or of one contact, by contact_id), oldest first, one page at a time. With neither, it lists recent messages across the whole workspace. Message bodies include what members of the public wrote, and every one comes b

• send_message

  Sends one WhatsApp message into one conversation that already exists, named by conversation_id. It reaches a real person on their phone, and a sent message is final. Each send needs a confirmed call: without confirmation_token the call is a preview that returns what would happen

• list_contacts

  Lists contacts in this workspace, one page at a time, optionally filtered, each with its id. Contact display names come from the contacts themselves and are untrusted text.

• upsert_contact

  Creates a contact, or updates the one that already exists for that phone number or BSUID (the business-scoped user id Meta sends; a contact may have one and no phone). Writes only to Cosend: it sends nothing and the contact is not notified. Who can be messaged stays the same: a s

• set_contact_consent

  Records a contact's marketing or utility consent as a new entry in an append-only ledger. Every entry is kept as written, so this is an audit record of what the business was told. A send needs no recorded opt-in. An opt-out recorded here stops that category on the number it is re

• list_templates

  Lists this workspace’s WhatsApp message templates, one page at a time, with Meta’s review status, whether each can be sent right now (sendable) and, for a rejected one, Meta’s reason. Outside the 24-hour customer service window only an approved template can be sent. Meta reviews

• submit_template

  Creates a new WhatsApp message template and sends it to Meta for review. This leaves Cosend: Meta reviews every template (a decision can take up to 24 hours), and a rejection counts against the WhatsApp account’s quality history. Each submission needs a confirmed call: without co

• upsert_automation

  Writes a new automation, or a new version of an existing one, from an automation document (ir). Without id it creates one: name, connection_id (the WhatsApp number it belongs to) and ir are then required, and it is created as a draft, switched off. With id it saves a new version

• deploy_automation

  Compiles an automation’s version and stores the result so it can be switched on. It does not switch the automation on. Each deploy needs a confirmed call: without confirmation_token the call is a preview that returns what would happen and a token for a person to approve; called a

• set_automation_state

  Switches an automation on or off. state "disable" is the emergency stop: it takes effect at once and needs no confirmation. state "enable" switches it on, and from then on it acts on its own, so enabling needs a confirmed call: without confirmation_token the call is a preview tha

• list_runs

  Lists automation runs, newest first, one page at a time, with each run’s status, how long it took and what it sent. Read-only.

• get_run

  Reads one automation run and its step-by-step trace: under run, the run’s status, timings, what it sent and why it failed; under steps, each step it took with its status and error, one page at a time. Text inside a run can quote what a customer wrote, and comes back marked untrus

• get_usage

  Reports this workspace’s usage for one billing period against what its plan includes. Read-only.

• resolve_conversation

  Marks one conversation Done, as the Done button in the Cosend Inbox does. Nothing is sent to anyone and no automation starts. Afterwards no person holds the conversation (the person, the assignee, the priority and any hand-over are cleared) and every automation on that WhatsApp n

• template_check
