BoostedTravel tools 14
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.- +2 more on the listing page

lavka_statusShow whether the Lavka session and delivery location are configured. Read-only. Call this first to check setup before other tools.set_locationSet the delivery location (required before catalog/cart calls). Provide either lat+lon coordinates or a saved address_id. Persists to config.list_addressesList your saved Lavka delivery addresses (by name). Read-only. Use a returned `label` with use_address to switch delivery to that place.use_addressSwitch delivery to one of your saved addresses, matched by name. Catalog, cart and prices are location-scoped, so this re-points everything. A saved address carries city/street/house; pass flat/entrance/comment if the order needs them.set_delivery_addressSet delivery to ANY address by free text — works for a new city. Resolves the address to coordinates + city/street/house via Lavka's own geo search. Example: set_delivery_address("Казань, улица Баумана, 1", flat="12").search_productsSearch the Lavka catalog at the current delivery location. Read-only. Each result has an `id` (use it with add_to_cart) and a `slug`; get_product takes either.get_productGet one product: price, size, stock, description, nutrition. Read-only. `product` is an `id` or `slug` from a search result, or a Lavka link (a lavka.yandex.ru/good/... page or a shared ...?item=<id> link). `nutrition` is the КБЖУ block exactly as the product card shows it, numbers as Lavka gives them (nothing recomputed), or null when the card has none (non-food items): - `per_100g`: {kcal, protein, fat, carbs} per 100 g, or null. - `per_portion`: the same per the card's other tab, with its `label` ("Всё блюдо", "На упаковку", "На 50 г", ...), or null if the card has only one tab. - `default_basis`: the only tab ("per_100g" / "per_portion") when the card has one; null when it has both (Lavka doesn't say which one opens). - `portion_grams`: the portion's weight when the card states it (from the label, or the item's weight for a whole dish/pack), else null. - `warning`: null, or a note that per_portion doesn't follow from per_100g for that weight — Lavka's own data is wrong then; don't log it blindly.view_cartShow the current cart contents and running total. Read-only. The cart also reports order-readiness. Watch these: - `warning`: a plain-language problem to fix (or null). If set, act on it. - each item's `unavailable_on_depot`: true = it's in the cart but CANNOT be ordered from the current store (only in «Большая Лавка», or sold out here). - `available_for_checkout`: false = the order can't be placed as-is. Remove/replace flagged items with update_cart_item(product_id, 0) before checkout.add_to_cartAdd a product to the cart (increments if already present). No charge. `product_id` is the `id` from a search result. Pass `price` from the same search result when available (Lavka validates it on cart writes). IMPORTANT: search can return items that are only stocked in «Большая Лавка» (a different store) — they add fine but can't be ordered from the current one. After adding, check the returned cart's `warning` and each item's `unavailable_on_depot`; drop any flagged item with update_cart_item(id, 0).update_cart_itemSet the exact quantity of a cart item. quantity=0 removes it. No charge.clear_cartRemove everything from the cart. No charge.checkout_previewPreview the order: items, delivery fee, ETA, address, payment, TOTAL. Charges NOTHING. Show the returned total to the user and ask them to confirm it out loud before calling confirm_order. Always run this before confirming. If the summary has a `warning`, or `available_for_checkout` is false, or any item has `unavailable_on_depot: true`, the order will be REFUSED — fix the cart (remove/replace those items) and preview again before confirming.- +5 more on the listing page
