What this server can do

5 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.

aviation_find_stations(bbox, state, station_ids)
Resolve an airport or weather reporting station by ICAO 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.). Station IDs must be 4-letter ICAO format (e.g., KSEA, KJFK). At least one of station_ids, bbox, or state is required.
aviation_get_advisories(bbox, hazard, advisory_type)
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.
aviation_get_metar(hours, station_ids)
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. Required: station_ids.
aviation_get_pireps(bbox, hours, station_id, distance_nm, altitude_max_ft, altitude_min_ft)
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. Coverage is US-centric; PIREPs are sparse and absence of reports does not imply smooth conditions.
aviation_get_taf(station_ids)
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). Required: station_ids.

Signals

These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.

Where to get it

Related, by what their authors tagged them

These share tags the maintainers applied themselves, such as metar, taf, aviation, cyanheads. Common tags like "mcp" or "ai" are ignored for this: agreeing with six hundred other projects is not a similarity.

This is not a recommendation and not a test result. It is a map of what the authors said their work is about.
