A side-by-side look at the BoostedTravel and Hotelbooking MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose BoostedTravel for travel & transportation work as a local process; choose Hotelbooking for travel & transportation over a hosted endpoint. You can also run both side by side in one mcpServers block.
LETSFG_BEARER_TOKEN, LETSFG_API_KEY.search_flights, resolve_location, unlock_flight_offer.Rows where the two servers differ are marked.

search_flightsSearch hundreds of airlines for live flight prices — completely FREE, unlimited, read-only.
Returns structured offers with prices, airlines, times, durations, and stopovers. Some offers carry `starlink` for in-flight Starlink Wi-Fi: "confirmed_all" / "confirmed_some" mean the carrier has FULLY fitted that aircraft type, "likely_all" / "likely_some" mean the rollout on that type is underway but incomplete. State only "confirmed_*" as fact; describe "likely_*" as "the airline is fitting this aircraft type, not guaranteed on your flight". Anything ending in "_some" has at least one leg WITHOUT it. An absent field means no information, NOT an absence of Wi-Fi. Covers airlines across all continents including low-cost carriers.
Search is async: this tool polls for you, including waiting out the late split-ticket merge.
Some offers are SPLIT TICKETS: two separately-issued tickets through a hub, each leg booked from whatever is cheapest for it (usually two different airlines), because no one seller offers the combination as a single ticket. They carry `split_ticket: "true"`, `combo_type: "virtual_interlining"` and `self_transfer: "unprotected"`. ALWAYS tell the user when an offer is a split ticket and what unprotected means: the tickets are not linked, so if the first flight is late and the connection is missed, the second airline owes nothing — no rebooking, no refund. Never present a split ticket as though it were one through-fare.
Requires LETSFG_BEARER_TOKEN or LETSFG_API_KEY. See letsfg://guide resource for the full authenticate->search->book workflow.resolve_locationConvert a city/airport name to IATA codes. Always call before search_flights if you only have a city name. Read-only, safe to call multiple times.unlock_flight_offer[Developer API only] Confirm live price with the airline and reserve the offer for 30 minutes.
NOT part of the agent flow and NOT needed before book_flight. It requires LETSFG_API_KEY (the paid, prepaid Developer API) and refuses to run on a Bearer token, because the PFS unlock endpoint does not exist — calling it that way used to 404.
If you authenticated with `letsfg auth`, go straight from search_flights to book_flight.
Requires a Developer API key. Legacy path — not idempotent.book_flightBook a flight from a search result.
FLOW: authenticate (once) -> search_flights -> book_flight
CHARGES: nothing from LetsFG. A completed booking pays the airline prices from airlines and the major booking sites.
RESULT: either {"booked": true, "order_id": "..."} or {"booked": false, "booking_url": "..."} — the second means the booking genuinely did not complete and nothing was charged. That is a normal outcome, NOT a transient error: do not retry, give the user the booking_url.
SAFETY: use REAL passenger details — names must match passport, email receives the e-ticket.get_flight_bookingPoll a flight booking started by book_flight. REQUIRED to learn the outcome: on a PFS Bearer token book_flight returns a booking_ref and state "booking_in_progress", not a PNR - the booking itself takes 4-11 minutes.
Call it every 20-30 s with that booking_ref until state is terminal:
completed -> PNR issued, card charged
failed -> the hold was released, nothing was charged
needs_attention -> a human is looking at it; do NOT rebook
Do not rebook while the state is still moving, and do not treat a slow poll as a failure - the money is HELD, not taken, until the airline confirms. Refs last one hour past the booking start.resolve_hotel_cityConvert a place name to the supplier city id that search_hotels needs. Always call this first if you only have a city name. Read-only and safe to repeat.
Use `Id` from the first result as city_id and `Name` as city_name.search_hotelsSearch real, bookable hotel inventory. Requires a payment method on file — the SAME card that authorises flight booking. That applies to search too, not just booking, because a search opens a real session at the supplier.
Only free-cancellation, pay-later rates are returned, so everything you see can actually be booked on these terms. The result set is smaller than a metasearch and that is deliberate.
`price` is what the guest pays. Keep `session_id` and the chosen offer's `combination_id_v2` — together they identify that exact rate, and book_hotel needs both. Takes up to a few minutes.book_hotelBook one hotel rate. Charges 5% of the price to the card on file immediately as a NON-REFUNDABLE reservation fee; the balance is paid directly to the supplier through the pay link we return, by balance_due_by (the supplier's own auto-cancellation date).
Returns a booking_job_id, NOT the booking — a booking takes minutes. Poll get_hotel_booking until status is succeeded or failed.
The fee is charged BEFORE the room is committed, so a declined card costs nothing: no reservation exists and nothing is charged.
Send expected_price and expected_balance back exactly as search returned them. NOT idempotent — calling twice for the same rate books the room twice and charges two fees.get_hotel_bookingCollect the result of a booking started with book_hotel. Poll every ~20s.
status is in_progress, succeeded or failed. On success you get confirmation, reservation_fee_charged, pay_link, balance_due, balance_due_by and the full cancellation ladder. Read-only and safe to repeat.cancel_hotel_bookingRelease a hotel reservation. Free until balance_due_by; after that the hotel's own ladder applies and can reach 100%. The ladder is in the booking terms, so check the cost first.
The 5% reservation fee is NOT refunded. Takes over a minute; if it times out do NOT assume it failed — re-check before retrying.authenticateExplain how to connect a card so this server can search and book. Nothing is charged to connect — a 0.00 Revolut setup that saves the card so a booking can be charged later.
Call with no arguments. It returns the current instructions and add_card_url (https://letsfg.co/connect). A PERSON must approve once in a browser — there is no endpoint that mints a token from card details, so do not ask the user for card numbers and do not try to automate this step.
Two ways in: (a) add LetsFG as a connector in an assistant that supports remote MCP servers and approve it, or (b) any OAuth-capable client can register itself — see https://letsfg.co/for-agents, section "Option B". Both land on the same card screen.
RETIRED 2026-09-02: the Stripe lanes (setup_url, setup_session_id, payment_method_id, card_token) and every token they issued. Passing them now fails.
This does NOT create a Developer API billing account. Do not use setup_payment for this.setup_payment[Developer API only — you almost certainly want `authenticate` instead] Attaches a card to a PAID prepaid Developer API account. Refuses to run unless LETSFG_API_KEY is set, because agents kept calling this and creating billing accounts they did not need.No tool names declared yet. Check the project README from the listing page.
Paste either block (or both) into your client config, e.g. claude_desktop_config.json or ~/.cursor/mcp.json. We only show a config when the install command is confirmed.
