Xweather Weather MCP: conditions, forecasts and alerts in your AI app

Get current conditions, a forecast or active weather alerts for a location by asking your AI app. Xweather Weather's hosted MCP server serves weather data from Vaisala Xweather. ContextGate connects it to Claude, ChatGPT and Cursor and records each weather call in Activity, so operations teams can see which conditions were checked before a decision.

  4. 4Ask your AI app whether any weather alerts are active for Houston tonight, then open Activity to see the Xweather call.
