OpenWeather MCP. Access Global Weather Data via Your AI Agent.

OpenWeather gives your agent global weather data. You pull real-time climate metrics and historical records for any location worldwide using this server.

First, you gotta map out where you are. If a user just throws a city name at ya—say, 'Miami' or 'Boston'—you run the geocode tool. It doesn't give you one answer; it spits back up to five matching locations, giving you precise coordinates, country codes, and state names for each match.

When you have those coordinates, you can start pulling data. You use reverse_geocode if you get coordinates but need the readable address—it converts lat/lon into city name, state, country, and postal code details.

Getting Current Conditions:
To check what's happening right now, you run get_current_weather. This pulls real-time data: temperature, wind speed, and atmospheric pressure. You can also use this tool with a simple city name if coordinates are unavailable.
For air quality right at this minute, you hit up the get_air_quality tool; it returns the current Air Quality Index (AQI) alongside pollutant concentrations like PM2.5 and Ozone levels.

Forecasting for Tomorrow:
If you need to look ahead, you've got options. For a quick glance at what's coming up, use get_forecast, which gives a short-term prediction covering up to five days in three-hour increments. You can also run the get_hourly_forecast tool for granular detail using coordinates; this spits out wind speed and UV index data hour by hour.
For planning further out, you've got get_daily_forecast, which gives a summary up to 16 days out, reporting minimum/maximum temperatures and the chance of precipitation.

If you just want a general forecast for a specific day without the hourly breakdown, run get_daily_forecast.

Air Quality Trends:
You don't just check today's air; you can predict it. The get_air_quality_forecast tool gives you a four-day look at air quality trends, predicting AQI levels and pollutant concentrations like PM2.5 over the next few days.

Historical Deep Dives & Safety:
For research or records, you use get_historical_weather. You gotta give it precise coordinates and an exact date in YYYY-MM-DD format; it then fetches specific metrics—temperature, humidity, wind speed—for that past day. If you need to know when the sun pops up or dips down, get_sun_times calculates those times, along with the sun's elevation angle, using coordinates.
If there's any heavy weather brewing, get_weather_alerts checks for active severe warnings and reports the alert type, severity level, and time window based on your provided location.

You can pull this whole package of data—current conditions, forecasts, air quality, and alerts—all from a single chat prompt after you get those coordinates.
