Scored across 17 tools
Each tool targets a distinct weather data source or domain (e.g., air quality, marine, specific models). There is no functional overlap; agents can easily select the correct tool based on the data type or model needed.
All tool names use lowercase snake_case with a descriptive noun or noun_verb pattern (e.g., weather_forecast, geocoding, dwd_icon_forecast). The naming is consistent and predictable across the set.
With 17 tools, the server covers a wide range of weather and climate data sources. While slightly larger than average, each tool serves a unique purpose and the count is justified by the breadth of the domain.
The tool set spans current forecasts, historical data, air quality, marine conditions, elevation, floods, seasonal outlooks, climate projections, ensemble forecasts, and multiple individual model forecasts. It comprehensively covers the weather and climate data domain.
