Publish Agent

Changes state - verify before retry Publishes a DRAFT version of an agent, making it live and immutable. Once published, that version can never be edited again — to make further changes afterward, use duplicate_agent to start a new draft. Optionally bind a phone number in the same call: inbound_phone_number_id / outbound_phone_number_id are only applied because this call is publishing — passing one without publishing has no effect elsewhere. Binding a number here claims it for that direction, releasing it from any agent currently using it. Use get_agent first to find the draft version_number to publish.

Parameters

Name	Type	Required	Description
`agent_id`	`string`	Yes	The agent ID, e.g. agent_abc123
`version_number`	`string`	Yes	The draft version number to publish, e.g. 0 — from get_agent
`inbound_phone_number_id`	`string`	No	Phone number ID to bind for inbound calls, e.g. phn_abc123 — from get_organization_phone_number.
`outbound_phone_number_id`	`string`	No	Phone number ID to bind for outbound calls, e.g. phn_abc123 — from get_organization_phone_number.

Before you call

Connect and initialize the MCP client with OAuth or an API key for the intended workspace.
Provide the required parameters: agent_id, version_number.

Example MCP request

Send tools/call after your client completes MCP initialization. Replace placeholder values with IDs and inputs from your workspace. For object and array parameters, follow the nested requirements in the parameter description instead of treating an empty value as complete.

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "publish_agent",
    "arguments": {
      "agent_id": "agent_abc123",
      "version_number": "1"
    }
  }
}

The server returns one text content block. Parse content[0].text as JSON when the tool succeeds. See MCP responses and errors for the full envelope and failure behavior.

Verify the result

Confirm the response is not marked isError. Call Get Agent to read the affected resource. Verify that the intended state is visible before making another change.

Retry safety

This tool changes workspace state. After a timeout, read the affected resource before retrying so you do not create duplicate or conflicting changes.
