Nws Weather Mcp Server

Connects Claude directly to the National Weather Service API with zero authentication required. You get seven tools covering the essentials: 7-day and hourly forecasts by coordinates, active alert searches with filtering by severity and event type, current observations from nearby stations, and narrative products like Area Forecast Discussions from any Weather Forecast Office. The coordinate-to-grid resolution happens automatically with caching, and observations come back in dual units. Useful when you need authoritative US weather data without managing API keys or parsing raw NOAA feeds. Available as a public hosted instance at nws.caseyjhand.com/mcp or self-hosted via npm.
