This project creates and advanced weather data platform, seamlessly integrating historical meteorological data from EUMETSAT with dual AI-powered weather forecasts from both Google's GraphCast and ECMWF's AIFS models. Built on the Model Context Protocol (MCP), it provides intelligent weather analysis capabilities through a unified API with ensemble predictions and model comparison tools.
The core WeatherMCPServer
class provides 6 advanced tools for comprehensive weather analysis, from individual AI model forecasts to sophisticated ensemble predictions that combine multiple data sources.

First, download and install Claude Desktop from the official Claude Desktop documentation.
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
π‘ 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"
}
}
}
}
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"
}
}
}
}
β No server startup required: Claude Desktop will automatically launch the MCP server when needed.
Close and reopen Claude Desktop for the changes to take effect.
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:

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 ofpython
