The Xweather MCP Server connects LLMs directly to Xweather's data platform. Simply ask a question and the model will fetch all relevant Xweather data to provide an answer that blends the model's extensive knowledge with the precision of our high quality datasets.
Xweather integrates global and regional data sources—including NOAA, the UK Met Office, DWD, JMA, AirNow, Copernicus, and others—to provide real-time and historical data on lightning, air quality, hail, road conditions, wildfires, hydrology, and more.
Lightning data is sourced from Vaisala's proprietary lightning network.

The Weather API gives you access to 65 endpoints covering conditions, forecasts, alerts, lightning, hail, road weather, air quality, fire weather, tropical systems, tides, and more. Historical data goes back to 2004 for conditions and 2016 for lightning. All endpoints use consistent request formats and return JSON responses.
Every request requires a client ID and client secret, provided when you create an account. Pass these as query parameters or use the SDKs, which handle authentication automatically. Full authentication details are in the documentation.
All endpoints return JSON by default. GeoJSON is available for geospatial queries. The API uses consistent request and response formats across all 65 endpoints.
Xweather’s weather API is built for compatibility with a wide range of programming languages and frameworks. For example, if you’re using a React-based framework like Next.js, you can easily fetch weather data on the server or client side using standard HTTP requests. Read the full tutorial on how to integrate a weather API into a Next.js project.
The Weather API runs on multi-region AWS infrastructure with global CDN. Historical uptime exceeds 99.99%. Enterprise support includes SLA options for mission-critical integrations.
API rate limiting is used to control the rate of requests sent and received from the Weather API. Its purpose is to prevent our clients from taxing system resources on our end, ensuring that the API runs efficiently for all clients at all times. It is a standard practice employed by APIs to help prevent performance hitches or outages. Learn more here.
The free tier includes 15,000 API accesses per month with full access to every endpoint. No credit card required, and it never expires. In the US and Canada, you can add a payment method to pay as you go for usage beyond 15,000 accesses. Outside the US and Canada, contact sales to increase your limit.
