Server tool list (5)
Raw names from tools/list. Only developers need these.
| aviation_find_stations | Resolve an airport or weather reporting station by its identifier, or discover stations within a bounding box or US state. Returns all identifier variants (ICAO/IATA/FAA), coordinates, elevation, and available data types (METAR, TAF, SYNOP, etc.). A lookup matches the registry's own identifier, which for an airport is its 4-letter ICAO ID (e.g., KSEA, KJFK); buoys and mesonet sites carry identifiers of other shapes and resolve by those. At least one of station_ids, bbox, or state is required. limit bounds how many stations an area search returns without changing the area searched, and belongs to the bbox and state modes only. |
| aviation_get_metar | Get current weather observations (METARs) for one or more airports. Returns decoded fields — wind direction/speed/gusts, visibility, ceiling with its kind (measured, or indefinite for vertical visibility into an obscuration), present weather, temperature, dewpoint, altimeter, cloud layers — plus the computed flight category (VFR/MVFR/IFR/LIFR) and the raw METAR string. Accepts 1–10 ICAO station IDs (e.g., KSEA, KJFK). Use aviation_find_stations to resolve or verify an ICAO ID, or to discover nearby stations. |
| aviation_get_taf | Get the Terminal Aerodrome Forecast (TAF) for one or more airports. Returns each forecast period with valid times, surface wind, low-level wind shear, visibility, decoded weather conditions, cloud layers, and the vertical visibility into a forecast obscuration, plus the raw TAF string. TAFs cover the next 24–30 hours and are issued only for airports with scheduled commercial service; check data_types from aviation_find_stations to confirm TAF availability. Accepts 1–4 ICAO station IDs (e.g., KSEA, KJFK). |
| aviation_get_pireps | Get recent Pilot Reports (PIREPs) near an airport or within a bounding box. Returns decoded turbulence, icing, and cloud reports with altitude, aircraft type, intensity, and the raw PIREP string. Requires either station_id (ICAO center point for radial search, e.g., KSEA) or bbox (area search) — not both. distance_nm belongs to the station_id search only, and altitude_min_ft must not exceed altitude_max_ft. min_intensity restricts the result to reports carrying a turbulence or icing layer at that intensity or above. limit bounds how many reports come back without changing what is searched, keeping the most recent. Coverage is US-centric; PIREPs are sparse and absence of reports does not imply smooth conditions. |
| aviation_get_advisories | Get active domestic SIGMETs for a region. Returns each advisory with hazard type (CONVECTIVE, TURBULENCE, ICING, IFR), severity, altitude range, valid period, polygon coordinates, and raw text. Coverage is US-centric (NWS Aviation Weather Center). This tool reads the domestic SIGMET feed only and cannot return an AIRMET; requests for one are rejected rather than answered with SIGMETs. During fair-weather periods no advisories may be active — an empty result is normal, not an error. Filter by advisory_type, hazard, or bbox. |
