Weather MCP Server1

A simple Model Context Protocol (MCP) server that exposes a get_weather tool. It fetches real-time weather for any GPS coordinates using the free Open-Meteo API — no API key required.

Tool

get_weather

Fetches current temperature, feels-like temperature, humidity, and wind speed for a given location.

Inputs:

• latitude (number) — latitude coordinate of the target location

• longitude (number) — longitude coordinate of the target location

Setup

git clone https://github.com/tarunmalpani/mcp-weather.git
cd mcp-weather
npm install

Usage

This server communicates over stdio, so it's meant to be launched by an MCP-compatible client, not run standalone.

Claude Code

Add a .mcp.json file in your project root (replace cwd with the absolute path where you cloned this repo):

{
  "mcpServers": {
    "weather": {
      "command": "npx",
      "args": ["tsx", "server.ts"],
      "cwd": "/absolute/path/to/mcp-weather"
    }
  }
}

Claude Desktop

Add the same mcpServers block to your claude_desktop_config.json (Settings → Developer → Edit Config).

After saving the config, restart the client. The get_weather tool will be available automatically.

Development

Run the server directly (useful for testing it starts without errors):

npm start
