  2. 02Retrieve forecasts by latitude and longitude
  3. 03Make asynchronous requests with httpx
  4. 04Handle retries through a request helper

Use cases

  1. 01Check active weather alerts for a state
  2. 02Get a forecast for specific coordinates

MCP support

This MCP server for Claude exposes get_alerts and get_forecast over stdio, using data from the U.S. National Weather Service API.

MCP Weather Server for Claude

This project implements an 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
await get_alerts("CA")

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
