Verdicts

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.

LiteAPI (Nuitee Connect)

Sandbox key at sign-up, same base URL as production, no card. Hosted MCP's documented setup puts the API key in the URL query string and exposes 111 generated tools.

Before you call either

Kiwi.com MCP Server

  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

LiteAPI (Nuitee Connect)

  1. Use /hotels/rates with a short hotelIds list from /data/hotels; a broad rates call is slow and large
  2. Always prebook before book and read the cancellation policy in the prebook response, since refundability differs per rate
  3. Send a unique clientReference on book; a repeat returns error 4005 instead of a second booking
  4. Set margin explicitly on every rates call. Zero means net rates with no commission to you
  5. Send the key to the MCP in an X-Api-Key header rather than ?apiKey= where the client allows it
