LetsFG

LetsFG offers flight and hotel search and booking to AI agents. The README says its server-side engine scans many sources, including Skyscanner, Kiwi, Kayak, Momondo and direct airline sites, and that search is free once you connect a card. You can add `https://letsfg.co/developers/api/mcp` as an MCP server in Claude, ChatGPT, Cursor or Windsurf, use the CLI, Python (`pip install letsfg`) or npm SDK, call a raw API, or just use the website. The code in the repo is MIT-licensed, but search and booking run on LetsFG's servers.

Money is involved, so read the terms. Connecting a card is described as a 0.00 Revolut setup with nothing charged. Booking holds the fare on your card and a LetsFG booking agent buys the ticket; the comparison table says flights have the fare plus a markup, with no separate fee. Hotels charge a 5% non-refundable reservation fee now and the remaining 95% only near the hotel's cancellation deadline, paid to the hotel. A separate Developer API for business use is prepaid, at $0.50 per search for the first 10 each month, then $0.20 and $0.10.

The README includes price comparisons against Google Flights (five routes) and Booking.com (three hotels), dated 2026-08-05, claiming savings each time. These are the vendor's own small samples. Its headline of "zero markup" also sits next to the pricing table saying a markup is held on flights, so check the final price at checkout. Last push was 2026-10-13. This review is based on the README and repository data; we have not run it ourselves or booked anything.
