LetsFG MCP lets Claude book flights with a mandatory human payment checkpoint
Efistoffeles · reddit · 2026-11-13
A developer launched LetsFG, an MCP server that lets Claude search and book flights and hotels, with one inviolable rule: Claude can search freely, but every booking requires a human to click a "Continue to payment" button that opens an external checkout via Revolut — neither Claude nor the server ever sees card numbers. The author accepts the drop-off at that step rather than letting AI spend money autonomously.
An unexpected constraint: due to EU travel law, flights and hotels can't be booked together — the second item for the same dates unlocks 24 hours later. Tip: book hotels first (prices are stickier; flights may drop next day).
Search is free and the tool is listed in Claude's directory. The author asks the community where they place human checkpoints in agents that can spend money or change real-world state.
