Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 48 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name flywhereto.

  • Pass
    Lists tools

    tools/list returned 8 tools.

  • Pass
    Current protocol

    Negotiated 2025-11-25. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 48 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 48 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Pass
    Parameters documented

    31 of 31 parameters have a description (100%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Pass
    Website matches publisher

    The website host matches the reverse-domain namespace.

  • Fail
    Source repo linked

    No repository URL is on file.

  • Not measured
    Repo owner matches

    This namespace is not an io.github login, so the owner comparison does not apply.

  • Pass

Capabilities

Tools 8

airline_routes

The full network one airline flies: every origin with its nonstop destinations, as IATA codes. Look up by IATA airline code ("TK") or name fragment ("turkish"). Ambiguous queries return a candidate list to refine from.

Discovered
destinations_from

All airports reachable nonstop from a given origin, with the service kinds (scheduled, seasonal, charter, suspended, ...) per destination. Optionally filter by kind and include the operating airlines. Seasonal and charter service carries no operating dates; treat as unverified for specific travel dates.

Discovered
find_airport

Look up airports by IATA/ICAO code or by name fragment. Returns code, name, country, coordinates and how many nonstop destinations each serves. Use this first when you only have a city or airport name.

Discovered
find_connections

Multi-stop itineraries from an origin airport to either a destination airport or to any airport in a country. Returns airport paths with every airline flying each leg. Airline entries carry their alliance and, when service is not plain scheduled, a kind field (seasonal, charter or suspended). Suspended legs are included and flagged, not excluded; pass exclude_kinds to drop them. Seasonal and charter service carries no operating dates and there is no frequency or days-of-week data, so treat every match as unverified for specific travel dates. Provide exactly one of destination or to_country. Responses include book deep links to Kiwi.com search results (our referral id included); without depart_date the link defaults to a one-way search two weeks out.

Discovered
find_meetup

Best meet-up airports for travellers from multiple origins, ranked by combined travel effort using the same scoring as the site. Origins can be weighted by traveller count. Scores are kilometre values, lower is better; optimize "score" and "total_distance" both rank by weighted total distance (the frontend default), "worst_case" by the longest single journey. Candidates everyone can reach always rank above candidates someone cannot. Route data only: no fares, no frequency or days-of-week data; non-scheduled legs are flagged with a kind field. The map link stores the query as an anonymous share code and reopens it in the site’s meet-up planner. Each reachable party carries a book deep link for its own journey to the candidate. Responses include book deep links to Kiwi.com search results (our referral id included); without depart_date the link defaults to a one-way search two weeks out.

Discovered
most_connected_airports

Airports ranked by number of nonstop destinations served, worldwide or within one country.

Discovered
reachable_from

How far the network stretches from one airport within a stop budget: totals, breakdown by stop count and by country. Pass country to list the individual reachable airports there with their minimum stops.

Discovered
route_details

Which airlines fly nonstop between two airports, with alliance, homepage and the service periods of each. Only periods of kind begins, ends or resumes ever carry dates; scheduled, seasonal and charter periods have none, so seasonal service is unverified for specific travel dates. Responses include book deep links to Kiwi.com search results (our referral id included); without depart_date the link defaults to a one-way search two weeks out.
