Managed Affiliate Partner status required; no self-serve key.\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### Booking.com Demand API\n\n1. Send both `Authorization: Bearer` and `X-Affiliate-Id`, or the call fails on auth\n2. Stay under 50 requests a minute in the sandbox and back off exponentially on 429\n3. Only accommodation flows book in the sandbox; cars and attractions won't\n4. Store the key at creation, it's never shown again\n5. Use filters and pagination on search to keep payloads small\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, Booking.com Demand API or Kiwi.com MCP Server?\n\nKiwi.com MCP Server scores 51.9 (D) on agent readiness against Booking.com Demand API's 38.1 (E), and leads in 5 of 7 scored categories.
