MCP-Server---Weather

# MCP Weather Server for Claude This project implements an [MCP](https://github.com/anthropics/mcp) server using the `fastmcp` interface, designed to serve as a Claude tool. It connects to the U.S. National Weather Service (NWS) API to provide real-time weather alerts and forecasts. ## ✨ Features - 🔔 **Get Active Alerts**: Retrieve current weather alerts by U.S. state. - 🌤️ **Get Forecast**: Fetch detailed forecasts by latitude and longitude. - ⚡ **Asynchronous & Fast**: Built with `httpx` and `fastmcp` for high-performance async operations. ## 🧠 Powered by Claude This server is built to serve as a Claude-compatible external tool via the MCP protocol, using `stdio` transport. ## 🛠️ Code Overview ### Main Components - `FastMCP`: Initializes the MCP server. - `make_nws_request()`: A helper for calling the NWS API with retries and headers. - `get_alerts(state: str)`: Claude-accessible tool to get weather alerts for a given U.S. state. - `get_forecast(latitude: float, longitude: float)`: Claude-accessible tool to get the forecast for any lat/lon pair. ### Example Tool Usage ```python await get_alerts("CA") await get_forecast(37.7749, -122.4194) ``` ### 🌐 External API National Weather Service API: https://weather.gov/documentation/services-web-api ### 📄 License MIT License. Feel free to fork, modify, and use this server as a base for your own Claude tools. ⸻
