FAQ from 🌤️ MCP Weather Server (Cursor + Node.js + WSL)

What does this MCP server do?

It provides a tool (getWhetherByCityName) that returns current weather data for any city name using the OpenWeatherMap API.

What are the prerequisites?

You need Cursor installed, WSL enabled with a Linux distribution, Node.js and npm in WSL, and an OpenWeatherMap API key.

How do I configure the server in Cursor?

In Cursor’s mcp.json (or settings UI), add a demo server with "command": "wsl" and "args": ["node", "/path/to/index.js"]. The env key does not work with wsl; use a .env file instead.

Where does the API key go?

Create a .env file in the project root with WHETHER_API_KEY=your_openweather_api_key_here. The server reads it using dotenv.

Can I run this server without WSL?

The README explicitly targets WSL. It does not document other environments.
