Weather MCP Server 🌤️

A Model Context Protocol (MCP) server that provides weather information tools. This server enables AI assistants like Claude to fetch real-time weather data, forecasts, and compare weather across different cities.

Features

• Current Weather: Get real-time weather information for any city

• Weather Forecast: Get weather predictions for up to 10 days (based on API plan)

• Weather Comparison: Compare weather conditions between two cities

• Supports both Celsius (metric) and Fahrenheit (imperial) units

Prerequisites

• Python 3.8 or higher

• WeatherAPI.com API key (free tier available)

Installation

1. Clone the repository

   git clone https://github.com/Abhishek3689/Weather_MCP_Server.git cd weather-mcp-server

2. Install dependencies

   pip install -r requirements.txt

3. Set up environment variables

   Create a .env file in the project root:

   WEATHER_API_KEY=your_api_key_here

Usage

🚀 Running The Server (Important!) 👉 If you double-click or run the file, you will NOT see results.

MCP servers do not show output directly.

They wait for Claude to connect to them.

But you can still start the server manually to ensure it’s working:

You would see somthing like this it means server is running correclty

Integration with Claude Desktop

To use this server with Claude Desktop, add the following to your Claude Desktop configuration:

On macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

On Windows: %APPDATA%\Claude\claude_desktop_config.json

Note : for 'command' write absolute location instead of only "python" by checking using in command prompt

you will see somthing like this

After updating the config, restart Claude Desktop.
