Crate rtk_cc_mcp 

rtk-cc-mcp — the plugin’s MCP server, spoken over stdio.

Claude Code launches this binary via .mcp.json and talks JSON-RPC to it on stdin/stdout. Two rules follow from that, and both are easy to get wrong:

1. stdout belongs to the protocol. Every log line goes to stderr. A stray println! corrupts the stream and the server appears to hang.
2. The process is long-lived. It stays up until Claude Code closes the pipe, so waiting() is what keeps it alive.

The tools here are rtk’s analytics surface. Three of them are read-only. The fourth, rtk_proxy, executes — see its doc comment.
