## Before you call it

1. POST to `https://mcp.kiwi.com` itself. `/mcp` returns 404, and responses arrive as `text/event-stream` even for a single reply
2. Send dates as dd/mm/yyyy and set `currency`, which defaults to EUR
3. Check the `error` field of every result. A rejected input returns `resultsCount` 0 with `isError` false
4. Narrow with `price_to`, `max_sector_stopovers` and `sort`. There is no limit parameter and each search returns 15 itineraries
5. Give the user `bookingUrl` to book. Don't call `feedback-to-devs` with user data, because it sends free text to Kiwi.com
