MCP server

API v1 is deprecated. It stops responding on 3 December, 2026. Build with API v2, and move an existing integration with the migration guide.

The Inboxapp MCP server gives AI tools direct access to the full REST API — threads, messages, prospects, tags, and more.

Authentication

The MCP server uses the same API token as the REST API. Pass it in the Authorization header.
