The 5 tools it gives your agent
Extracted from the project's README - what aviation-weather-mcp-server lets an agent do.
- aviation_find_stations
- - Resolve airports and weather stations by ICAO ID, bounding box, or US state. Returns ICAO/IATA/FAA IDs, coordinates, elevation, and available data types.
- aviation_get_metar
- - Get current weather observations (METARs) for one or more airports. Returns decoded wind, visibility, ceiling, present weather, temp/dewpoint, altimeter, cloud
- aviation_get_taf
- - Get Terminal Aerodrome Forecasts for one or more airports. Returns each forecast period with valid times, surface wind, low-level wind shear, visibility, decode
- aviation_get_pireps
- - Get recent Pilot Reports near an airport or within a bounding box. Returns decoded turbulence, icing, and cloud reports with altitude, aircraft type, intensity,
- aviation_get_advisories
- - Get active domestic SIGMETs for a region. Returns hazard type (CONVECTIVE, TURBULENCE, ICING, IFR), severity, altitude range, valid period, polygon coordinates,
