It is a Model Context Protocol (MCP) server that provides weather data via the free Open-Meteo API. No API key or registration is required. Sydney is set as the default city, making it particularly useful for Australian users. The server is designed to be used with Claude Desktop.
Install dependencies with npm install, then start the server with npm start. To use with Claude Desktop, add a configuration entry to claude_desktop_config.json pointing the node command to the server's src/index.js file. No other configuration is needed.

The server depends on `@modelcontextprotocol/sdk` (the official MCP SDK) and `node-fetch` for HTTP requests. No other heavy external libraries are needed.
Check the spelling, try adding a country code (e.g., "Paris, FR"), or use the `search_cities` tool to find the correct city name and coordinates.
Node.js version 16 or higher is required. You can check with `node --version`.
Open-Meteo is free with no API key or registration, offers 7-day forecasts (versus 5 days in OpenWeatherMap’s free tier), and is built on stable European weather models. Both have similar accuracy and reliability ratings.
