LetsFG
Agent-native flight search. 102 airline connectors fire in parallel — Ryanair, EasyJet, Wizz Air, Southwest, AirAsia, Qantas, and 96 more — plus enterprise GDS/NDC providers (Amadeus, Duffel, Sabre, Travelport) through the LetsFG backend. One tool call scans the entire world for flights, including airlines your agent didn't know existed.
Your agent doesn't need to build a flight integration. It doesn't need to scrape. Just add this MCP server and it can search and book flights in seconds.
### Why?
Flight websites inflate prices with demand tracking, cookie-based pricing, and surge markup. The same flight is often **$20–$50 cheaper** through LetsFG — raw airline price, zero markup.
### How it works
`search_flights` fires all relevant connectors in parallel on your machine + queries enterprise GDS sources in the cloud. Results come back merged, deduplicated, sorted by price. ~5 seconds for a full global search.
### Tools
| Tool | What it does | Cost |
|------|-------------|------|
| `search_flights` | Search 400+ airlines | Free |
| `search_hotels` | Search hotels worldwide | Free |
| `resolve_location` | City/airport → IATA code | Free |
| `get_agent_profile` | Your usage & profile | Free |
| `unlock_flight_offer` | Confirm live price, reserve 30 min | Free |
| `setup_payment` | Attach Stripe payment | Free |
| `book_flight` | Book with real PNR + e-ticket | Ticket price only |
**Search is free forever. Booking charges the raw airline ticket price via Stripe — we add zero margin.**
`LETSFG_API_KEY` is optional. Without it, the server runs all 102 local connectors. With it, you also get 400+ airlines via enterprise GDS/NDC sources.
### Pricing
- **Personal use** — completely free. Search, unlock, book. No limits.
- **Commercial use** — 1% fee (min $1 USD) per booking, collected via Stripe Connect. Search and unlock are still free.
- **First 1,000 GitHub stars** — star the repo and link your GitHub username to get free unlimited access (personal & commercial). No trial, no catch.
