Connector gateway (MCP)

The gateway through which the Cowork desktop calls the tools of services connected to the Bitrix24 account. It speaks MCP Streamable HTTP without sessions.

Base URL: https://vibecode.bitrix24.com/v1 | Authorization: Cowork desktop key

Who can call it

Only the key the Cowork desktop receives at sign-in. Any other key gets 403 CONNECTOR_KEY_NOT_ALLOWED.

While the feature is off, the path answers 404 ROUTE_NOT_FOUND to any request, before the key, the method and the body are checked. If the feature is on only for some Bitrix24 accounts or users, a key outside that group gets the same 404 right after the key check.

Request

POST /v1/connectors/mcp

POST /v1/connectors/mcp accepts a single JSON-RPC 2.0 message up to 256 KiB; a batch of messages is rejected. Methods: initialize, ping, tools/list, tools/call. With the feature on, GET and DELETE answer 405.
