Weather MCP Server 🌤️

A Model Context Protocol (MCP) server that provides real-time weather information for any city using the Open-Meteo API.

Features

• 🌍 Get current weather for any city worldwide
• 🌡️ Returns temperature in Celsius
• 💨 Provides wind speed in km/h
• 📍 Includes geographic coordinates
• 🐳 Fully containerized with Docker
• 🚀 Easy to deploy and use

Quick Start

Using Docker (Recommended)

Pull and run the pre-built image from Docker Hub:

docker pull 125478963/weather-mcp:latest
docker run -d -p 8000:8000 125478963/weather-mcp:latest

The server will be available at: http://localhost:8000/mcp

Building from Source

1. Clone this repository:

git clone https://github.com/rajeevchandra/weather-mcp-docker.git
cd weather-mcp-docker

2. Build the Docker image:

docker build -t weather-mcp .

3. Run the container:

docker run -d -p 8000:8000 weather-mcp

Usage

This MCP server exposes a weather tool that can be used by MCP clients like Claude Desktop.

Available Tool

weather(city: str)

• Returns current temperature (°C) and wind speed (km/h) for the specified city
• Default city: Philadelphia

Example Response

{
  "city": "London",
  "latitude": 51.5074,
  "longitude": -0.1278,
  "temperature_c": 15.2,
  "windspeed_kmh": 12.5
}

Configuration

The server runs on:

• Host: 0.0.0.0 (accessible from outside the container)
• Port: 8000
• Endpoint: /mcp

Using with MCP Clients

Claude Desktop

Add this to your Claude Desktop MCP settings:

{
  "mcpServers": {
    "weather": {
      "url": "http://localhost:8000/mcp"
    }
  }
}

Development

Prerequisites

• Python 3.11+
• Docker (optional, for containerization)

Local Development

1. Install dependencies:

pip install -r requirements.txt

2. Run the server:

python server.py

Testing

Run the complete test script to verify the server is working:

python complete_test.py

This will:

1. Initialize a session with the MCP server
2. List available tools
3. Test the weather tool with multiple cities (London, Paris, Tokyo)
4. Display real-time weather data

Expected Output:

✅ Session initialized successfully!
Server: WeatherMCP
Version: 1.20.0

🌍 Getting weather for London...
   ✅ Success!
      Temperature: 14.2°C
      Wind Speed: 15.3 km/h

Or use the quick health check:

curl http://localhost:8000/mcp

How It Works

1. Geocoding: Converts city names to coordinates using Open-Meteo Geocoding API
2. Weather Data: Fetches current weather data using Open-Meteo Weather API
3. MCP Protocol: Exposes weather data through the Model Context Protocol

API Credits

This server uses the Open-Meteo API which is free and requires no API key.

Troubleshooting

Server not responding?

Check if the container is running:

docker ps | grep weather-mcp

View logs:

docker logs <container-id>

Port already in use?

Use a different port:

docker run -d -p 8080:8000 125478963/weather-mcp:latest
