Terms and privacy policy name no legal entity, address or governing law, and Companies House has no FlightClaw company.\n\n**Kiwi.com MCP Server.** A keyless flight search with one typed, read-only tool, 47 filters and a booking link on every itinerary. It can't book, hold, change or cancel, and it has no published rate limits, changelog, terms or version. Each search returns 15 itineraries with no way to ask for fewer.\n\n## Before you call either\n\n### FlightClaw\n\n1. Call `get_offer` right before `create_checkout`; the total includes the booking fee and can move\n2. Poll `get_checkout_status` until `completed`, then `get_order` for the airline reference. A sent link isn't a booking\n3. Never ask for card numbers in chat. Hand over `checkout_url`, or pay it with a Link virtual card the user approved for the exact total\n4. Budget 100 searches a day per signed-in user, and use `search_multi_city` instead of many single searches\n5. Save the traveller once with `save_traveler` so later bookings don't re-ask for passport details\n\n### Kiwi.com MCP Server\n\n1. POST to `https://mcp.kiwi.com` itself. `/mcp` returns 404, and responses arrive as `text/event-stream` even for a single reply\n2. Send dates as dd/mm/yyyy and set `currency`, which defaults to EUR\n3. Check the `error` field of every result. A rejected input returns `resultsCount` 0 with `isError` false\n4. Narrow with `price_to`, `max_sector_stopovers` and `sort`. There is no limit parameter and each search returns 15 itineraries\n5. Give the user `bookingUrl` to book. Don't call `feedback-to-devs` with user data, because it sends free text to Kiwi.com\n\n## Questions\n\n### Which is better for AI agents, FlightClaw or Kiwi.com MCP Server?\n\nKiwi.com MCP Server scores 51.9 (D) on agent readiness against FlightClaw's 45.3 (E), and leads in 6 of 7 scored categories.
