Overview

What is Weather MCP Server?

A Model Context Protocol (MCP) server that provides weather data from the National Weather Service API. It delivers weather forecasts by geographic coordinates and alerts by US state in a clean, formatted way for LLM consumption, and integrates with Claude and other MCP-compatible clients.

How to use Weather MCP Server?

Install Node.js and dependencies (npm install), then build (npm run build). Run directly with npm start or ./dist/index.js. Connect to Claude Desktop by adding a server entry in the claude_desktop_config.json file, then restart Claude and test with queries like "What's the weather in Sacramento?" or "Are there any active weather alerts in Texas?"

Frequently asked questions

What runtime does Weather MCP Server require?

Node.js (LTS version recommended) and npm or yarn.

Where does the weather data come from?

The server uses the National Weather Service API, so data is limited to United States locations.

Does Weather MCP Server provide historical weather data?

No, only current conditions and forecasts are available.

How do I connect the server to Claude Desktop?

Edit your Claude Desktop configuration file (`~/Library/Application Support/Claude/claude_desktop_config.json` on macOS) and add a server entry with the command `node` and args pointing to the built `dist/index.js`.

What tools does Weather MCP Server expose?

Two tools: `get_forecast` (requires latitude and longitude) and `get_alerts` (requires a two-letter US state code). There is also a resource template `weather://{state}/alerts`.
