LetsFG MCP server

by LetsFG · official

Your AI can search flights and hotels and book them, with nothing booked until you approve by email.

LetsFG is a service that searches flights and hotels from many airlines and booking sites, then shows you one total price. This MCP server connects that service to your AI assistant, so you can just ask for a trip and get real options back. It is handy if you plan trips or book travel for work and hate opening a dozen tabs.

What is an MCP server? The 30-second version

On its own, your AI can only chat with you. An MCP server is a small helper that gives your AI a new skill or a connection to a service. This one connects your AI to LetsFG, so when you ask about a flight or hotel, the AI can look up real prices and times there for you. Nothing is booked until you approve it by email.

What this MCP server does

You tell your AI where you want to go, the dates, and how many people. The AI uses this helper to ask LetsFG, which checks hundreds of airlines, nearby airports, bag prices and on-time records. LetsFG sends back the best options with one total price, and your AI shows them in the chat. If you pick one, your AI can start a booking, but nothing is charged or ticketed until you approve it by email.

What you can do with it

Search flights between two cities on the dates you choose
Compare prices across airlines and nearby airports
Check bag fees and each flight's on-time record
Search hotels for your stay and compare total prices
Start a flight booking and hold the fare
Get a real airline booking reference once you approve

Try asking your AI

“Find me the cheapest flight from Chicago to Paris on September 16, returning September 24, for one person with a carry-on bag”
“What nearby airports should I check for a trip from San Francisco to London in October?”
“Show me hotels near the main train station in Warsaw for two nights, free cancellation only”
“Book the second option and hold it, I will confirm by email”

What it gives back to you

You get a short list of flights or hotels in the chat, each with the price, times, airline or property name, and notes like bag fees or on-time record. If you start a booking, you get a status and, once approved, a real airline booking reference. Prices stay the same if you run the search again. Nothing is charged until a booking is confirmed.

Before you start

What you need

An AI assistant that can use MCP servers, like Claude, ChatGPT, Cursor or Windsurf
A LetsFG connection approved once at letsfg.co/connect, one tap, no card
A card on file before your first booking (nothing is charged to add it)

Good to know

Booking holds the full price on your card and a real ticket or room is bought once you approve by email, so only approve a trip you actually want.
