What it does

LetsFG connects an AI agent to the letsfg.co server-side travel search and booking engine. Flight search covers hundreds of airlines and major booking sites and can assemble connections from separate carriers' tickets; hotel search returns real rates marked refundable or non-refundable. Search is free and booking is real: the price is held on the connected card, a LetsFG operator buys the ticket, and the hold is captured only once a real airline PNR exists. The tools are available as a hosted MCP server over a URL and as a local server via npx, and the same engine can be called from a CLI after pip install. Booking requires connecting a card once through letsfg.co/connect and getting a token.

Who it is for. For agent developers and people who want to search and book flights and hotels straight from an assistant.

Example request

Find the cheapest nonstop flights from Istanbul to Barcelona on April 15 and show the refund conditions

Limitations

This is an interface to the commercial letsfg.co service, not a standalone tool. Search is free, but booking charges real money and the service margin is inside the ticket price. Booking requires connecting a payment card through letsfg.co/connect and getting a token, and hotel search beyond the per-booking limit becomes paid. Booking needs real passenger data, which goes to the service and the seller. The separate Developer API is a paid product for high volume that most agents do not need. Availability of letsfg.co from some regions is not guaranteed.

How to disable. Remove the letsfg entry from the client's MCP config or turn off the connector. The local package is removed via npm, the CLI via pip uninstall letsfg. Card access is revoked on the letsfg.co side.

• Books real flights and hotels and holds payment on the connected card
• Requires real passenger passport and contact details
• Talks to the external commercial letsfg.co service and its sellers

README in short

The README presents LetsFG as a way to give an AI agent flight and hotel search and booking through the letsfg.co server-side engine. Server search covers hundreds of airlines and major booking sites, assembles cross-airline connections and expands a city into all its airports. Three paths are shown: MCP, CLI and SDK for personal and agent use, a direct API call with a Bearer token, and a separate paid Developer API for high volume. Connecting via the hosted MCP server goes through consent at letsfg.co/connect, where a card is connected without a charge, and issues a token that searches and books. The local server installs via npx letsfg-mcp, the CLI via pip install letsfg. MIT licensed.
