🖥️ Claude Desktop Integration

Step 1: Install Claude Desktop

First, download and install Claude Desktop from the official Claude Desktop documentation.

Step 2: Configure Claude Desktop

Create or edit the MCP configuration file:

Linux/Debian:

~/.config/Claude/claude_desktop_config.json

macOS:

~/Library/Application Support/Claude/claude_desktop_config.json

Windows:

%APPDATA%\Claude\claude_desktop_config.json

Step 3: Add Weather MCP Server

📡 Stdin/Stdout Transport (Recommended)

Add this configuration to your Claude Desktop config:

{
  "mcpServers": {
    "weather-mcp": {
      "command": "/path/to/weather-mcp-server/.venv/bin/python",
      "args": ["/path/to/weather-mcp-server/weather_mcp/mcp_server.py", "stdio"],
      "env": {
        "PATH": "/path/to/weather-mcp-server/.venv/bin:/usr/local/bin:/usr/bin:/bin",
        "AIFS_ENABLED": "true",
        "GRAPHCAST_ENABLED": "true",
        "ENSEMBLE_ENABLED": "true"
      }
    }
  }
}

⚠️ Important: Update the paths to match your actual installation directory!

Example for typical installation:

# If installed in /home/username/weather-mcp-server/
{
  "mcpServers": {
    "weather-mcp": {
      "command": "/home/username/weather-mcp-server/.venv/bin/python",
      "args": ["/home/username/weather-mcp-server/weather_mcp/mcp_server.py", "stdio"],
      "env": {
        "PATH": "/home/username/weather-mcp-server/.venv/bin:/usr/local/bin:/usr/bin:/bin",
        "AIFS_ENABLED": "true",
        "GRAPHCAST_ENABLED": "true",
        "ENSEMBLE_ENABLED": "true"
      }
    }
  }
}

✅ No server startup required: Claude Desktop will automatically launch the MCP server when needed.

Step 4: Restart Claude Desktop

Close and reopen Claude Desktop for the changes to take effect.

Step 5: Test the Integration

Ask Claude Desktop advanced weather questions:

Basic Forecasts:

  • "Get an AIFS weather forecast for the Canary Islands"
  • "Show me a GraphCast forecast for latitude 28.29, longitude -16.63"
  • "What's the weather timeline for Las Palmas - past week and next week?"

Advanced AI Comparisons:

  • "Compare AIFS and GraphCast models for the Canary Islands"
  • "Create an ensemble forecast combining all models for Las Palmas"
  • "Which AI model is more accurate for European weather?"

Comprehensive Analysis:

  • "Get a complete weather analysis with historical data and ensemble predictions"
  • "Show me model agreement between AIFS and GraphCast for tomorrow's weather"

Available MCP Tools

Your weather MCP server now provides 6 advanced tools:

Core Weather Tools:

  1. get_graphcast_forecast - Google GraphCast AI predictions (1-16 days)
  2. get_historical_weather - EUMETSAT satellite data (1-30 days back)
  3. get_complete_weather_timeline - Combined historical + forecast data

New AIFS & Ensemble Tools: 4. get_aifs_forecast - ECMWF AIFS AI predictions (1-30 days) 5. compare_ai_models - AIFS vs GraphCast model comparison 6. get_ensemble_forecast - Multi-model ensemble predictions

Troubleshooting

Server not connecting?

  • Check the log file: ~/.config/Claude/logs/mcp-server-weather-mcp.log
  • Verify Python virtual environment path is correct
  • Ensure all dependencies are installed: pip install -r requirements.txt

Command not found errors?

  • Use absolute paths in the configuration
  • On Debian/Linux, use python3 or full venv path instead of python
