`forecast`

Pack: open-meteo · Endpoint: https://gateway.pipeworx.io/open-meteo/mcp

“What’s the weather in [city]” / “weather forecast for [location]” / “will it rain tomorrow” / “temperature in [place] this week” / “wind / precipitation / humidity forecast” — global weather forecast up to 16 days ahead, hourly or daily, at any lat/lng. Returns temperature, precipitation, wind, humidity, cloud cover, weather codes by default; pass hourly/daily arg for custom variables. Free, keyless, no signup (Open-Meteo / ECMWF + national weather services). Pair with geocode to convert “Paris” → lat/lng first.
