What this server can do

6 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.

ourairports_find_airports(type, limit, latitude, longitude, radius_km, include_closed)
Find airports within a radius of a latitude/longitude, ranked nearest-first by great-circle distance, each with its distance (km) and bearing (degrees true) from the query point. The grounding tool for "nearest airport to here" — pair it with a live aviation server to fetch weather or positions for the result. Takes a coordinate only: no geocoding, so resolve place names to lat/lon upstream first (e.g. an OpenStreetMap or Open-Meteo geocode tool). Closed airports are excluded unless include_closed is set. OurAirports is community-edited — not authoritative for flight operations. Required: latitude, longitude.
ourairports_find_navaids(type, limit, latitude, longitude, radius_km, airport_code)
Find navigation aids (VOR, VOR-DME, DME, NDB, NDB-DME, TACAN, VORTAC) two ways: spatially, by passing latitude+longitude (with an optional radius_km); or relationally, by passing airport_code to get the navaids that serve that airport. Supply exactly one mode — both or neither is a validation error. Coordinate mode ranks nearest-first with distance (km) and bearing (degrees true). Frequencies are stored in kHz for every navaid type (a VOR on 114.5 MHz reads frequencyKhz 114500) and are also surfaced in MHz. Airport mode returns an empty list (not an error) when the airport exists but has no associated navaids; an unknown airport_code is an error. OurAirports is community-edited — not authoritative for flight operations.
ourairports_get_airport(code, include)
Fetch the full record for one airport resolved by ANY code — IATA (SEA), ICAO (KSEA), GPS, national/local, or the OurAirports ident — with its runways and radio frequencies inline. The single `code` param is resolved case-insensitively across all five identifier spaces (priority: ident, then ICAO, IATA, GPS, local). The response always echoes the airport's complete code set and a resolution_note naming which space matched, so a wrong resolution from an ambiguous national code is self-correcting (re-query with the IATA or ICAO code, or the ident). Absent codes are reported as null, never an error. Closed airports always resolve. OurAirports is community-edited — not authoritative for flight operations. Required: code.
ourairports_list_countries(continent, include_regions)
List the countries present in the bundled OurAirports dataset with their ISO 3166-1 alpha-2 codes and airport counts. This is the lookup table for valid `country` (and, with include_regions, `region`) filter values used by ourairports_search_airports. Optionally restrict to a continent or nest each country's regions. Counts exclude closed airports.
ourairports_search_airports(type, limit, query, region, country, include_closed)
Search the bundled OurAirports corpus by free-text (name / municipality / keywords) and/or facets (country, region, type). Every query token must match (word order and partial words are handled). Returns ranked airport summaries — operational and larger airports first — each with its full code set and coordinates, ready to chain into ourairports_get_airport. Closed airports are excluded unless include_closed is set. Use ourairports_list_countries for valid country/region codes. For "nearest airport to a coordinate" use ourairports_find_airports instead. OurAirports is community-edited — not authoritative for flight operations.
ourairports_search_runways(type, limit, region, country, lighted, surface, min_width_ft, min_length_ft, include_closed_runways, include_closed_airports)
Search runways across the whole bundled OurAirports corpus by attribute, joined back to their airports — the cross-airport counterpart to ourairports_get_airport (which returns runways for one already-known airport). Filter by airport facets (country, region, type) and runway facets (surface, min_length_ft, min_width_ft, lighted). Returns one flat {airport, runway} row per matching runway, so an airport with three matching runways contributes three rows. `surface` is a case-insensitive substring match against the raw upstream surface string, not an exact code — the runway surface must CONTAIN your text, so a shorter fragment matches more variants (no controlled vocabulary: "asp" matches ASP, ASPH, and Asphalt). A runway whose length or width is unknown is excluded when the matching min_*_ft filter is set — the data can never confirm it meets the threshold. Closed airports and closed runways are both excluded unless their include_* flag is set. Use ourairports_list_countries for valid country/region codes. OurAirports is community-edited — not authoritative for flight operations.

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 aviation, bun, 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.
