## Capabilities

### Get Current Weather Status
Retrieve immediate readings including temperature, humidity, and wind speed for a specific geographic area.

### Predict Future Conditions
Access detailed forecasts with customizable time intervals, letting you plan minute-by-minute or day-by-day.

### Check Environmental Health
Monitor local air quality and pollution indices to assess safety levels for outdoor operations.

### Analyze Past Data
Fetch recent weather records, letting you analyze environmental trends over the last 24 hours or more.

### Review Active Warnings
List all current severe weather alerts and warnings issued for a specified region.

## Use Cases

### Rerouting a Fleet During Storms
A logistics manager needs to move goods through the Midwest, but a storm track develops. They ask their agent for the forecast and use `get_weather_forecast` to identify areas hit by severe weather, rerouting the entire fleet before any delays happen.

### Planning an Outdoor Festival
An event organizer needs to know if a weekend outdoor market is safe. They run `list_weather_alerts` and check the air quality via `get_air_quality`, ensuring they have enough time to secure vendors against predicted wind gusts.

### Diagnosing Crop Stress
An agronomist notices wilting crops. They use `get_recent_history` and combine it with the real-time data from `get_realtime_weather` to determine if a recent heat spike or change in humidity was responsible for the poor yield.

### Emergency Preparedness Check
A facility manager needs to know if they can operate safely after a local incident. They check `get_realtime_weather` for current wind speeds and use `get_air_quality` to confirm that pollution levels are safe for personnel reentry.

## Benefits

- Eliminate guesswork on field operations. Instead of relying on general forecasts, using `get_realtime_weather` gives your agent immediate data like wind speed and humidity for instant operational checks.
- Plan with precision. Need to account for changing conditions? The ability to use `get_weather_forecast` lets you plan logistics hour by hour or day by day, improving route reliability dramatically.
- Prioritize safety instantly. Before an event starts, running `list_weather_alerts` ensures your agent knows if there are active warnings—like flash flood or high wind advisories—that require immediate action.
- Optimize resource use. Agronomists can check historical trends using `get_recent_history`. This data helps them determine if the last week's rainfall was unusually low, guiding better irrigation plans.
- Monitor public health risks. By calling `get_air_quality`, your agent automatically checks for pollution spikes (like high PM2.5) and can advise users to postpone outdoor activities when air safety is compromised.

## How It Works

The bottom line is you tell your AI client what information you need, and it handles all the API calls to get accurate weather data back.

1. Subscribe to this MCP on Vinkius and enter your Tomorrow.io API Key.
2. Your AI client connects, making the environmental data available as an accessible toolset.
3. You prompt your agent with a request (e.g., 'What will the air quality be in San Francisco tomorrow?') and it executes the necessary function.
