Live aircraft positions and airspace-activity summaries, keyless.

None. No key, no signup.

What this pack actually calls

Not OpenSky. OpenSky Network blackholes datacenter egress — the connection hangs with no response and no reset, from Cloudflare Workers and from a non-CF relay alike, with valid OAuth2 credentials. It works from a residential IP, which is what makes it look fixable; it is not, and credentials do not change it. Do not spend time trying again.

The tools keep the OpenSky names because that is what agents reach for, and serve the same live picture from the keyless community ADS-B mirrors: adsb.lol → airplanes.live → adsb.fi, tried in that order. Every response carries a source field naming the mirror that answered and a note saying the data is not OpenSky’s.

State vectors are returned in OpenSky’s field names and units — metres and m/s, not readsb’s feet and knots — so code written against the OpenSky shape keeps working rather than silently misreading altitudes.

Tools

ToolCall it asReturns
get_statesopensky_get_statesLive state vectors, filtered by icao24 or by lat/lon/radius_nm
get_aircraftopensky_get_aircraftWhere one aircraft is right now, by ICAO24 hex
get_flightsget_flightsHistorical flight legs — not available, returns an explicit not-available result naming what does work
airspace_activityairspace_activityAircraft count, country breakdown, altitude and airborne split over a named region

Two of these names are also exported by other packs (country-state-city has its own get_states; flights and adsb both have get_aircraft), so on the full catalog the gateway exposes this pack’s as opensky_*. The middle column is what you actually call there. On a scoped connection — /opensky/mcp — the bare names work, because there is nothing to collide with.

What is not available, and why

Historical endpoints. The community mirrors are live-only, and OpenSky is the only source of “which airports did this aircraft fly between last Tuesday”. get_flights therefore returns found: false with a reason rather than answering a past-window question with a live snapshot.

There is no global “every aircraft right now” query either — the mirrors serve a circle around a point, so get_states needs either an icao24 filter or a location. Called with neither, it says so and gives the arguments to retry with.

Coverage caveats

  • Receiver-based. Mid-ocean, and areas with few ground receivers, are thin.
  • Military and state aircraft routinely disable transponders, so airspace_activity undercounts non-civilian traffic. Read it as a civilian-aviation normalcy signal, not an order of battle.
  • Regions larger than the feeds can cover in one pass report coverage: "partial", and their counts are a floor, not a total.
  • origin_country is derived from the ICAO 24-bit address block, which is allocated by country of registration — it is not transmitted by the aircraft. Only blocks confirmed against live registrations are mapped (validated at 1,125 aircraft agreeing, 0 conflicts); anything else reports unknown rather than guessing.
  • flights — get_flight_route (callsign → airline and route), get_arrivals / get_departures (live airport activity inferred from ADS-B)
  • adsb — the same mirror chain with readsb-native field names and units
  • aviation-weather — METAR/TAF/SIGMET for the airports involved
  • faa-delays — FAA ground stops and delay programs for US airports
