Weather forecast
Use Open-Meteo (openmeteo) from fastCRW Pergamon, capability "Weather forecast" (forecast). You have a latitude and longitude and need the weather there, with no account or key. Example options: latitude=52.52, longitude=13.41, current=temperature_2m,wind_speed_10m. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "openmeteo" and capability "forecast". Tell me the credits used and cite the licence from the response. If the crw MCP tools are missing, install them with: npx -y crw-mcp install --api-key <your fastCRW API key>
