What it can do

Tool names and descriptions exactly as the server reported them on Nov 7, 2026. The maker wrote them, not us; we show them as plain text.

  • sos_check_rights

    Checks a cancelled, delayed, overbooked or missed-connection flight against EU261, UK261 and US DOT rules. Returns the law that applies, up to three options (refund, re-routing), the care the airline owes (meals, hotel), a compensation range per passenger with its conditions, war

  • sos_desk_script

  • sos_airport_help

    Lists hotel, lounge and transfer search links for an airport, nearby alternative airports with directions, and who pays for a hotel under EU and UK rules. Links only, nothing is booked. Covers about 100 airports in Europe, North America and Asia.

  • sos_find_alternatives

    Searches live one-way flights from the traveller's airport and airports within 300 km to their destination on one date, ordered by earliest arrival, with price in EUR, stops, ground distance to the alternative airport and rail operator links for trips under 1,200 km. Returns 10 o

  • sos_prepare_case

    Checks the details for a case handled by the SOS Flights team (rebooking help, hotel, evidence and follow-up) and returns what will be submitted, the price (a one-time fee, or covered by a valid access code) and a confirmation_token valid for 15 minutes. Nothing is created or cha

  • sos_open_case

    Opens the case prepared with a confirmation_token, after the traveller confirmed it. Returns the case code, which is the key to the case afterwards, the case page and either a payment link (the case becomes active after payment) or, with an access code, an active case.

  • sos_get_case

    Returns the status of an SOS Flights case by its case code: whether it is active, the team's recommended solution once there is one, the last 10 chat messages for chat cases, and the case page link.

  • sos_prepare_message

    Checks a message from the traveller to the SOS Flights team on an active chat case and returns it with a confirmation_token valid for 15 minutes. Nothing is sent. WhatsApp cases continue in WhatsApp.

  • sos_send_message

    Sends the message prepared with a confirmation_token to the SOS Flights team, after the traveller confirmed it. The team's reply appears in the case status and on the case page.

Common questions

Is SOS Flights safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.0) reached the registry 18 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?
