Crate origin_mcp_stdio 

MCP over stdio.

The client starts the application as a child process and talks to it over its standard streams — no port to allocate, no token to exchange, and it works while the GUI is not running.

stdout belongs to the protocol

Nothing else may write there. A single log line corrupts the stream and the client reports a parse error, which points nowhere near the actual cause. Configure logging with TelemetryConfig::for_stdout_protocol before serving.

Functions

serve

Serve until the client closes stdin.

serve_streams

Serve over arbitrary streams. Used by the tests, which is the point of the split.
