git clone <your-repo-url>
cd mcp-server

2. Create a .env file in the project root with your API keys:

# WeatherAPI.com API Key
WEATHER_API_KEY=your_weather_api_key_here

# Groq API Key
GROQ_API_KEY=your_groq_api_key_here

Running the Service

Development Mode

To run the weather service in development mode:

uv run mcp dev server/weather.py

Install and Run

To install and run the service on desktop claude:

uv run mcp install server/weather.py

Setting up weather.json

The weather.json configuration file is required for the chat interface.

1, Testing your server with Claude for Desktop:

• Open VS Code and run:

  code $env:AppData\Claude\claude_desktop_config.json

• Add the following configuration:

  {
      "mcpServers": {
          "weather": {
              "command": "uv",
              "args": [
                  "--directory",
                  "C:\\ABSOLUTE\\PATH\\TO\\YOUR\\mcp-server",
                  "run",
                  "server/weather.py"
              ]
          }
      }
  }

• Replace C:\\ABSOLUTE\\PATH\\TO\\YOUR\\mcp-server with your actual project path

2. For Chat Interface (client.py):

   • The weather.json file should be in your server directory

   • Make sure it contains:

     {
         "mcpServers": {
             "weather": {
                 "command": "uv",
                 "args": [
                     "--directory",
                     "C:\\ABSOLUTE\\PATH\\TO\\YOUR\\mcp-server",
                     "run",
                     "server/weather.py"
                 ]
             }
         }
     }

   • Replace C:\\ABSOLUTE\\PATH\\TO\\YOUR\\mcp-server with your actual project path

3. Restart Claude for Desktop after making changes
