Overview

What is MCP Weather?

MCP Weather is a Python application that serves as an MCP (Model Context Protocol) tool, allowing AI assistants to access real-time weather information from the National Weather Service (NWS) API. It provides two main functions: retrieving active weather alerts for any US state and obtaining detailed weather forecasts for any US location by latitude and longitude.

How to use MCP Weather?

Clone the repository, ensure Python 3.13+ and the uv package manager are installed, then run uv run weather.py. To integrate as an MCP tool, use the command PATH/uv --directory ABSOLUTE_PATH/mcp-weather run weather.py. The server exposes two tools: Get Weather Alerts (parameter: state – two-letter US state code) and Get Weather Forecast (parameters: latitude, longitude).
