Locale Format MCP runs on your own machine — the client starts it, so there is no endpoint to ping. 503 installs a week from npm. Last commit 2 Nov 2026.
Format numbers, currencies, dates and relative times for any locale using ICU data - fully local.
Today is the operative word: we check Locale Format MCP every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
