Nager Date MCP runs on your own machine — the client starts it, so there is no endpoint to ping. 209 installs a week from npm. Last commit 8 Nov 2026.
Nager.Date: public holidays for ~100 countries - by year, upcoming, with local names - keyless.
Today is the operative word: we check Nager Date MCP every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
