MCP Servers

Get MCP Server Signals

Pre-release Endpoint This endpoint is currently in beta and is subject to change.

Client-initiated signals fetch with long-polling capabilities. The client supplies capabilities as a deepObject query parameter:

Keys are capability names (e.g. mcp)
Values contain the capability request fields (version)

Example:

GET /mcp-cp/{controlPlaneId}/signals?capabilities[mcp][version]=5

The CP responds with a JSON payload containing zero or more signals that the client should process. If no signals are available, the CP responds with HTTP 304 Not Modified.

get/v1/mcp-cp/{controlPlaneId}/signals

Query parameters

Capability requests as a deepObject map.

Keys are capability names (e.g. mcp).
Values contain the capability request fields (version).

Response

The MCP server signals response.
