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

This project is a simple Model Context Protocol (MCP) server that provides real-time weather data using the OpenWeatherMap API, built with Node.js and designed to run inside WSL (Windows Subsystem for Linux).

📦 Features

Exposes an MCP tool: getWhetherByCityName
Fetches weather data for any city using OpenWeatherMap
Compatible with Cursor AI client
WSL support with clean .env configuration

🛠️ Prerequisites

Cursor installed
WSL enabled with Ubuntu or other Linux distro
Node.js and npm installed in WSL
OpenWeatherMap API key

🔧 Installation

# In WSL terminal
git clone https://github.com/your-username/mcp-weather-server
cd mcp-weather-server
npm install

🔐 Environment Setup

Create a .env file in the root of the project:

WHETHER_API_KEY=your_openweather_api_key_here

🌱 The server will read this key using dotenv.

🧠 MCP Configuration (in Cursor)

In your Cursor's mcp.json (or settings UI), use the following:

{
  "mcpServers": {
    "demo": {
      "command": "wsl",
      "args": ["node", "/home/kaif/code/learnings/mcp-poc/index.js"]
    }
  }
}

✅ Note: env key won't work properly when using wsl. Use a .env file instead.

🚀 Running the Server

In Cursor, create a new MCP Client using the demo server. Then run queries like:

getWhetherByCityName({ name: "London" })

The server will respond with current weather data for that city.
