Baseline MCP runs on your own machine — the client starts it, so there is no endpoint to ping. 143 installs a week from pypi. Last commit 6 Oct 2026.
Statistically rigorous weather and climate context: forecast plus 35-year historical ranking.
Nothing serious here today
Today is the operative word: we check Baseline MCP every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
