Weatherai
Connects Claude, Cursor, or Windsurf to live weather data through 11 tools including current conditions, 14-day forecasts, historical lookups, air quality, astronomy, and solar irradiance. The standout is ask_ai_weather, which interprets plain English questions and routes them to the right endpoints automatically. Runs as a hosted HTTP endpoint at api.weatherai.io, so no local setup needed. Free tier covers 1,000 standard calls and 50 premium calls daily. Good for building agents that need to reason about weather conditions, trip planning assistants, or anything that combines location awareness with atmospheric data. Authentication is a simple API key in the URL or headers.
