Key features

  1. 01City weather lookup
  2. 02OpenWeatherMap API data
  3. 03`getWhetherByCityName` tool
  4. 04Cursor client configuration

From the project README

🌤️ 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.

New to MCP?

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
