# Aviation Weather MCP for real-time data. AI Agent Connect

> Aviation Weather MCP provides direct access to official NOAA Aviation Weather Center data. Your AI agent can pull decoded METAR observations, TAF forecasts, SIGMET/AIRMET hazards, and pilot reports for any airport. It handles the heavy lifting of decoding raw meteorological data into actionable flight categories like VFR, MVFR, IFR, or LIFR.

## Description

You can now give your AI agent the same weather intelligence used by dispatchers and pilots. This MCP connects your client to the NOAA Aviation Weather Center, providing decoded data without requiring you to manage API keys. Instead of parsing raw text strings, your agent receives clear information on wind, visibility, cloud ceilings, and flight categories. You can check specific airport conditions, scan entire regions for hazards, or listen to real-time pilot reports regarding turbulence and icing. Whether you need to know if a specific terminal forecast will hold for an arrival or if a SIGMET is currently affecting a flight path, this MCP delivers the raw and decoded data needed to make informed decisions. It turns complex meteorological observations into direct answers about flightability and weather hazards.

## Tools

### get_airport_weather
This tool reads current weather at a specific airport. It provides decoded METAR observations including wind, visibility, and ceiling, along with the terminal forecast (TAF).

### find_airports
This tool searches the FAA airport database for locations within a bounding box. It returns ICAO and IATA codes, names, tower status, and radio frequencies.

### list_terminal_forecasts
This tool lists Terminal Aerodrome Forecasts (TAF) for specific station IDs or a defined area. It provides the forecast wind, weather, and cloud conditions as issued.

### list_observations
This tool lists decoded METAR observations for stations or a geographic area. It includes wind, visibility, ceiling, temperature, and flight category for each station.

### get_pilot_reports
This tool retrieves pilot reports (PIREPs) near an airport or within a bounding box. It captures actual in-flight reports of turbulence and icing at specific flight levels.

### list_significant_weather
This tool lists active SIGMETs and AIRMETs over the contiguous United States. It includes details on convective, turbulence, icing, and low-ceiling hazards, including altitude and movement.

### summarize_area_conditions
This tool aggregates observations, SIGMETs, and pilot reports for a specific area in one request. It provides a single view of flight categories and reported hazards for a region.

## Prompt Examples

**Prompt:** 
```
What's the weather doing at Los Angeles International right now, and is it likely to hold for an arrival this evening?
```

**Response:** 
```
At KLAX the observation at 1500Z is flight category MVFR. Wind is 190 degrees at 3 knots, visibility is 10 statute miles, with a scattered layer at 1,900 feet and an overcast ceiling at 2,400 feet. The TAF suggests the overcast will stay near 2,500 feet through the evening, so an arrival looks fine but the ceiling is worth re-checking.
```

**Prompt:** 
```
Is it flyable around Chicago this afternoon, or are flights being held?
```

**Response:** 
```
In the Chicago area, 42 stations reported. 28 are VFR, 9 are MVFR, 4 are IFR, and 1 is LIFR. The IFR conditions are concentrated along the lakeshore where the ceiling is near 700 feet. No SIGMETs are active and pilot reports only mention light turbulence below 6,000 feet.
```

**Prompt:** 
```
Are there any SIGMETs in force right now, and is the turbulence over the Rockies real?
```

**Response:** 
```
Eight convective SIGMETs are in force over the contiguous US. The strongest, SIGMET 95C, covers Colorado and Wyoming with tops to 35,000 feet. Pilot reports within 200 nautical miles of Denver confirm light-to-moderate clear-air turbulence between 14,000 and 17,000 feet.
```

## Capabilities

### Weather Decoding
Your agent converts raw METAR and TAF text into clear flight categories like VFR or IFR.

### Hazard Monitoring
The agent tracks active SIGMET and AIRMET warnings across the contiguous United States.

### Real-time PIREPs
Your agent accesses actual pilot reports for turbulence and icing encountered in flight.

### Airport Discovery
The agent finds ICAO codes, tower status, and radio frequencies using bounding box searches.

### Regional Summaries
Your agent aggregates observations and hazards into a single view for a specific geographic area.

## Use Cases

### Pre-flight Planning
Check the TAF and current METAR for a destination to determine if the flight category is VFR or IFR.

### Route Hazard Assessment
Scan for SIGMETs and AIRMETs along a planned flight path to identify convective activity or icing.

### In-flight Updates
Use pilot reports to check if turbulence reported by other crews is present in your current flight level.

### Arrival Feasibility
Determine if a low ceiling at a destination airport will cause delays or diversions using decoded ceiling data.

## Benefits

- Eliminates the need to manually decode complex METAR and TAF text strings.
- Provides direct access to official NOAA data without managing API credentials.
- Consolidates observations, hazards, and pilot reports into single regional queries.
- Translates meteorological data into standard flight categories for faster decision making.

## How It Works

Connecting to this weather data is a one-click process through Vinkius.

1. Subscribe to the Aviation Weather MCP in the Vinkius catalog.
2. Connect your preferred MCP-compatible client like Claude or Cursor.
3. Ask your agent for weather at a specific airport or region.
4. The agent calls the necessary NOAA tools to fetch and decode the data.
5. Receive plain-English weather summaries and hazard reports.

## Frequently Asked Questions

**Do I need an API key?**
No. This reads the public NOAA Aviation Weather Center Data API, which requires no key or account.

**Why is my airport code rejected?**
The observation endpoints take the 4-letter ICAO code only — KLAX, not LAX or ORD. Call find_airports with a bounding box (south,west,north,east) around the place and read the ICAO column; "@TX" is also accepted as a station list meaning every station in Texas.

**What do VFR, MVFR, IFR and LIFR mean?**
They are flight categories the source derives from ceiling and visibility: VFR is fine for visual flying, MVFR is marginal, IFR requires instrument qualification and LIFR is the worst — the conditions that hold departures and divert arrivals. summarize_area_conditions counts them across a region.

**What is a pilot report and why would I trust it?**
A PIREP is what a crew actually met in flight — turbulence or icing at a stated flight level, with the aircraft type and an intensity from LGT to SEV. It is the only measurement of conditions between the ground and cruise, and it is voluntary: an empty answer usually means nobody found anything worth reporting.

**Why are there no SIGMETs for my region outside the United States?**
This reads the domestic SIGMET and AIRMET products, which cover the contiguous United States. Observations themselves are global — METARs are filed for airports worldwide — but the hazard products are US-only, so summarize_area_conditions lists SIGMETs only for boxes over the US.
