Calendar MCP runs on your own machine — the client starts it, so there is no endpoint to ping. 177 installs a week from pypi. Last commit 30 Sep 2026.
Google Calendar for LLM agents: find, create, update, move, delete events; free/busy; scheduling.
Nothing serious here today
Today is the operative word: we check Calendar MCP every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
