LetsFG
An MCP server, CLI and Python/JavaScript SDK for searching and booking real flights and hotels through AI agents, holding the fare on a card only when a booking actually completes.
LetsFG gives an AI agent flight and hotel search and booking through one function call, covering airlines worldwide plus major booking sites, and free-cancellation hotel rates that hold the room with a small upfront charge and let the balance be paid later by link, up to the hotel's own deadline. Search is free; when a booking completes, the fare is held on the user's card and a LetsFG booking agent buys the ticket, returning the airline's own PNR.
Agents connect over MCP; approving the connection opens a one-tap flow that asks for a card only at the first booking. Scripts can call the same endpoints with a bearer token, and a separate paid developer API exists for high-volume commercial use.
It is distributed as an MCP server, a command-line tool, and Python and JavaScript/TypeScript SDKs.
