Open-Meteo MCP Server

A comprehensive Model Context Protocol (MCP) server that provides access to Open-Meteo weather APIs for use with Large Language Models.

Features

This MCP server provides complete access to Open-Meteo APIs, including:

Core Weather APIs

• Weather Forecast (weather_forecast) - 7-day forecasts with hourly and daily resolution
• Weather Archive (weather_archive) - Historical ERA5 data from 1940 to present
• Air Quality (air_quality) - PM2.5, PM10, ozone, nitrogen dioxide, pollen, European/US AQI indices, UV index and other pollutants
• Marine Weather (marine_weather) - Wave height, wave period, wave direction and sea surface temperature
• Elevation (elevation) - Digital elevation model data for given coordinates
• Geocoding (geocoding) - Search locations worldwide by name or postal code, get coordinates and detailed location information

Specialized Weather Models

• DWD ICON (dwd_icon_forecast) - German weather service high-resolution model for Europe
• NOAA GFS (gfs_forecast) - US weather service global model with high-resolution North America data
• Météo-France (meteofrance_forecast) - French weather service AROME and ARPEGE models
• ECMWF (ecmwf_forecast) - European Centre for Medium-Range Weather Forecasts
• JMA (jma_forecast) - Japan Meteorological Agency high-resolution model for Asia
• MET Norway (metno_forecast) - Norwegian weather service for Nordic countries
• Environment Canada GEM (gem_forecast) - Canadian weather service model

Advanced Forecasting Tools

• Flood Forecast (flood_forecast) - River discharge and flood forecasts from GloFAS (Global Flood Awareness System)
• Seasonal Forecast (seasonal_forecast) - Long-range forecasts up to 9 months ahead
• Climate Projections (climate_projection) - CMIP6 climate change projections for different warming scenarios
• Ensemble Forecast (ensemble_forecast) - Multiple model runs showing forecast uncertainty
