Search and book flights and hotels: hundreds of airlines, plus pay-later hotel rates.
Copy the AI prompt to install this server into Claude Code, Cursor, or another agent β or use 1-click editor setup below.
We haven't yet run this listing's install command through our automated sandbox check. This isn't a red flag β we're steadily working through the catalog.
π‘ Paste the JSON block into your client's configuration file under mcpServers, then restart the application.
Finding a flight or hotel shouldn't mean checking 47 tabs. Or 3 hours of searching.
Or having that feeling you could've got a better deal if you'd just waited a little longer.
So we built something about it.
No markup. No tracking. No price that goes up because you looked twice.
Hundreds of airlines. Real prices. One function call.
LetsFG gives your AI agent flight and hotel search and booking superpowers. Our server-side engine scans the entire world for the cheapest price. Search is free. Booking is real: the fare is held on your card, a LetsFG booking agent buys the ticket, and you get the airline's PNR.
The same flight costs $20β$50 less because you skip OTA inflation, cookie tracking, and surge pricing.
Agents: add https://letsfg.co/developers/api/mcp as an MCP server. Approving the connection opens letsfg.co/connect, where you add a card in a 0.00 Revolut setup (nothing is charged, no Revolut account needed). That token searches for free and books. Scripts: send the same token as Authorization: Bearer to the PFS endpoints. Developer API: a separate paid product for high-volume commercial use; most agents do not need it. β Get started
We searched 5 routes on Google Flights and LetsFG on the same day (2026-08-05), for flights departing 2026-09-16. Same airline, same number of stops β LetsFG was cheaper every time:
| Route | Airline | Google Flights | LetsFG | You Save |
|---|---|---|---|---|
| LAX β Paris (CDG) | JetBlue, 1 stop | $363 | $334 | $29 |
| SFO β London (LHR) | JetBlue, 1 stop | $349 | $333 | $16 |
| LA β New York (JFK) | JetBlue, nonstop | $174 | $157 | $17 |
| London β Singapore (SIN) | Shenzhen Airlines, 1 stop | $395 | $380 | $15 |
| Chicago β Dubai (DXB) | Air Canada + Emirates, 2 stops | $517 | $461 | $56 |
$133 cheaper across 5 routes in a verified comparison (2026-08-05). Google Flights inflates on repeat searches; LetsFG returns the same prices however often you run the search, because it reads airlines and the major booking sites directly rather than tracking you.
Why the difference? Google Flights only searches its own limited set of airline partners. LetsFG searches everywhere β Skyscanner, Kiwi, Kayak, Momondo, plus direct airline websites (Ryanair, United, Southwest, EasyJet, Spirit, Norwegian, AirAsia, and hundreds more). More sources = better prices. No demand-based inflation and no cookie tracking: the same search returns the same prices however often you run it.
Same hotel, same room type, same 2-night stay, same free-cancellation policy β checked on the same day (2026-08-05) for a 2026-09-16 check-in:
| Hotel | Booking.com | LetsFG | You Save |
|---|---|---|---|
| Hotel Boss, Warsaw | $206 | $169 | $37 |
| ibis Styles Paris Gare de l'Est | $663 | $525 | $138 |
| Copthorne Tara Hotel, London Kensington | $379 | $347 | $32 |
$207 cheaper across 3 hotels in a verified comparison (2026-08-05), matching each property's own free-cancellation rate against Booking.com's free-cancellation rate for the identical dates and room type. Prices quoted in PLN at booking, converted to USD at that day's rate.
Why the difference? LetsFG sells at wholesale cost β no markup for demand, no loyalty-program cross-subsidy. You're not paying for the room upfront: 5% books it now, and the remaining 95% isn't due until the hotel's own cancellation deadline. Cancel before that deadline and you lose nothing but the 5%; the rest was never charged. Only free-cancellation, pay-later rates are sold, so every price shown is one you can actually hold risk-free.
