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.

Good fit when

  • You want the agent to search flights and hotels across many sources in one call
  • You want to compare real airline prices without an aggregator markup
  • You want the agent to place a booking with a real PNR after a human confirms

Not a fit when

  • You have no connected card and token, so booking is unavailable
  • You cannot share real passenger passport and contact details with the service
  • You need a one-off answer without connecting an MCP server

Environment variables

LETSFG_API_KEY secret
Alternative to the token: a key for the separate paid Developer API for high volume.

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.

FAQ

Is search paid?

No, flight search is free. Money moves only at booking: the price is held on the card and captured once a real PNR exists, and a failed booking releases the hold.

How does the agent get access?

Through the hosted MCP server: the consent step opens letsfg.co/connect to connect a card and issues a token that searches and books. The separate paid Developer API is not needed for most agents.

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.
