Example Use Cases

• 1

  Retrieve active weather alerts for a given US state (e.g., get_alerts("CA")).

• 2

  Obtain detailed hourly/daily forecasts for a specific location using latitude and longitude (e.g., get_forecast(38.5816, -121.4944)).

• 3

  Integrate real-time U.S. weather data into conversational assistants or dashboards via the MCP protocol (e.g., integration with Claude for Desktop).

Description

This MCP server provides weather alerts for US states and detailed forecasts for specific latitude/longitude coordinates using the National Weather Service API. It exposes two programmatic tools: get_alerts(state) to retrieve state-level alerts and get_forecast(latitude, longitude) to fetch forecasts for a location. The project is designed to be run locally (requires Python 3.12+ and the uv package manager) and can be integrated with agents such as Claude for Desktop. Note that the underlying NWS API only covers locations within the United States.
