harmony-mcp runs on your own machine — the client starts it, so there is no endpoint to ping. 49 installs a week from npm.
Repo rules enforcement for AI agents. Checks diffs against repo conventions.
Today is the operative word: we check harmony-mcp every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
