Installation

To use with Claude Desktop, add the server config:

On MacOS: ~/Library/Application Support/Claude/claude_desktop_config.json On Windows: %APPDATA%/Claude/claude_desktop_config.json

{
	"mcpServers": {
		"Weather-mcp": {
			"env": {
				"WEATHER_API_KEY": "xxx"
			},
			"command": "node",
			"args": ["/your/path/to/mcp-weather/build/index.js"]
		}
	}
}

You'll need to obtain a free API key from WeatherAPI.com and set it in your environment configuration.

Debugging

Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the MCP Inspector, which is available as a package script:

npm run inspector

The Inspector will provide a URL to access debugging tools in your browser.
