Ask ChatGPT or Claude with SOS Flights tools - URL: https://www.sosflights.help/blog/sos-flights-mcp-ai-assistant/ - Published: 2026-10-11T07:56:27.000Z - Updated: 2026-10-11T12:23:22.000Z - Description: Connect the free SOS Flights MCP server to ChatGPT, Claude or Claude Code. Check your EU261 rights, get a desk script and find live flights in one chat. - Author: Codeblocks - Tags: Travel Help, Scripts & Evidence > **Short answer:** SOS Flights runs a free MCP server at `https://www.sosflights.help/mcp`. Add it to ChatGPT, Claude or any MCP client. You need no login and no account. Then ask about your flight in plain words. The assistant checks your EU261, UK261 or US DOT rights, writes what to say at the desk, and searches live alternative flights. You are in a queue. Your flight is cancelled. You already have ChatGPT or Claude on your phone. Ask it. If it can use SOS Flights tools, it stops guessing. It answers from a rules engine that was checked against the regulation. ## What the SOS Flights tools do The server gives your assistant nine tools. You can use four of them for free. They need no sign-up. | Tool | What you get | Cost | | ------------------------------------- | -------------------------------------------------------------------------------------------------------------------------- | -------------- | | sos\_check\_rights | The law that applies, your options, the care the airline owes you, and a compensation range with its conditions | Free | | sos\_desk\_script | One to three polite sentences to say at the desk, in English, Slovak, Czech, German, Polish, Hungarian, Italian or Spanish | Free | | sos\_airport\_help | Hotel, lounge and transfer links for about 100 airports, nearby airports, and who pays for the hotel | Free | | sos\_find\_alternatives | Live one-way flights from your airport and nearby airports, sorted by earliest arrival | Free | | sos\_prepare\_case \+ sos\_open\_case | A case for the SOS Flights human team, opened only after you confirm | Paid, one time | The tools never book, cancel or change your booking. They advise. You decide. ## Set it up in two minutes 1. **ChatGPT:** Settings → Apps & Connectors → Advanced settings → Developer mode. Choose Create. Paste `https://www.sosflights.help/mcp`.

Give the airports, the airline and what happened. For example: > "My Ryanair flight from Vienna to Barcelona is cancelled tonight. They say it is a technical problem. What are my rights, and what do I say at the desk?" The assistant calls `sos_check_rights` and `sos_desk_script`. You get your options, the care you are owed and a script to read aloud. Then ask: "Find me another flight tonight, also from nearby airports." It calls `sos_find_alternatives`. ## A real answer, from the live server We asked the server about a cancelled flight from Vienna (VIE) to Barcelona (BCN), with an overnight wait and a technical cause. This is a summary of what it returned: - **Law:** EU261, because the flight departs from an EU airport. - **Options:** a refund within 7 days, re-routing at the earliest opportunity (also on another airline), or re-routing at a later date of your choice. - **Care:** meals, two calls or messages, a hotel and transport to it. - **Later:** a compensation range, with the conditions that apply. - **Desk script:** "Under EU Regulation 261/2004, please re-route me to my final destination at the earliest opportunity, including on another airline if that is sooner." The same facts are in our guide [flight cancelled: what to do in the next 30 minutes](https://www.sosflights.help/blog/flight-cancelled-what-to-do/). The assistant brings them to your exact flight. ## Why use the tools and not a plain chatbot? A plain chatbot answers from memory. It can mix up countries, thresholds and amounts. The SOS Flights tools return structured results: - **The right law.** EU261, UK261 or US DOT, chosen from your airports and airline. - **The right numbers.** Delay thresholds and compensation bands by distance, with conditions. - **Sources.** Each rights result names its sources and a "last verified" date. - **No made-up flights.** Alternatives come from a live flight search, not from guesses.

The airline does not answer. The desk is closed. You travel with children. Then ask the assistant to open an SOS Flights case. It first shows you what it will send and the price. Nothing happens until you confirm. Payment is on our own payment page. You get a case code. Our team then works with you on WhatsApp or in the chat. If the airline is not answering at all, read 7 ways to reach a human at the airline fast. ## Is my data safe? The rights, desk, airport and flight tools do not store the flight details you give them. The server logs only the tool name, the client, the language and the duration. A case stores what you choose to send to the team.
