MCP Weather Server 🌤️

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

📋 Description

This project implements an MCP server that allows AI models to obtain current weather information for any location worldwide. The server uses Open-Meteo's free APIs for geocoding and weather data.

🚀 Usage

MCP Configuration

To use this server with an MCP client, add the following configuration to your mcp.json file:

{
    "mcpServers": {
        "Weather": {
            "command": "bunx",
            "args": [
                "-y",
                "tsx",
                "C:\\full\\path\\to\\project\\src\\main.ts"
            ]
        }
    }
}

Available Tools

get-weather

Gets weather information for a specific location.

Parameters:

• location (string): Location name (city, country, etc.)

Usage Example:

// Request
{
    "tool": "get-weather",
    "arguments": {
        "location": "Madrid"
    }
}

// Response
{
    "content": [
        {
            "type": "text",
            "text": "{
                \"latitude\": 40.4375,
                \"longitude\": -3.6875,
                \"current\": {
                    \"temperature_2m\": 18.7,
                    \"relative_humidity_2m\": 54,
                    \"precipitation\": 0,
                    \"rain\": 0,
                    \"cloud_cover\": 4,
                    \"wind_speed_10m\": 6.1
                }
            }"
        }
    ]
}

Workflow

1. Request reception: Server receives a request with a location

2. Geocoding: Location coordinates are obtained using Open-Meteo API

3. Weather query: Weather data is queried using the coordinates

4. Structured response: Data is returned in structured JSON format
