Nws Weather MCP Server is answering right now. Last checked moments ago. 343 installs a week from npm. It exposes 7 tools. Last commit 14 Sep 2026.
Get US weather forecasts, active alerts, and current observations.
Every tool that appeared, vanished or quietly changed what it asks for. Recorded since 13 August 2026. No other catalogue keeps this.
Today is the operative word: we check Nws Weather 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 one needs environment variables set before it will start:
NWS_USER_AGENT (User-Agent header for NWS API requests. The API requires this header but a default is provided.), MCP_HTTP_HOST (The hostname for the HTTP server.), MCP_HTTP_PORT (The port to run the HTTP server on.), MCP_HTTP_ENDPOINT_PATH (The endpoint path for the MCP server.), MCP_AUTH_MODE (Authentication mode to use: 'none', 'jwt', or 'oauth'.), MCP_LOG_LEVEL (Sets the minimum log level for output (e.g., 'debug', 'info', 'warn').).
The author declared them in the registry entry; get the values from the project itself.
