Configure the MCP server in Claude Desktop: enable Developer mode, then edit claude_desktop_config.json to point to the server’s index.js file and set the envPath to your .env file containing your OpenWeatherMap API key. After that, ask Claude about weather for a specific city (e.g., “台中天氣如何?”) and allow the MCP service when prompted.
