MCP Imslp runs on your own machine — the client starts it, so there is no endpoint to ping. 152 installs a week from npm. Last commit 6 Nov 2026.
Read IMSLP, the Petrucci Music Library: works, scores, editions, copyright. No API key.
Today is the operative word: we check MCP Imslp every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
