NOAA WW3 MCP Server runs on your own machine — the client starts it, so there is no endpoint to ping. 45 installs a week from pypi. Last commit 4 Sep 2026.
GFS-Wave (WAVEWATCH III) forecasts and NDBC buoy wave observations
Every tool that appeared, vanished or quietly changed what it asks for. Recorded since 9 August 2026. No other catalogue keeps this.
Today is the operative word: we check NOAA WW3 MCP Server every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.
