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
Print and Mail Company tools 14
get_price_quoteUse this when the user asks what it costs to send a physical letter by post (snail mail), including a registered letter. Returns the exact total incl. Luxembourg VAT (for a signed-in EU business customer with a confirmed VAT number: excl. VAT under the reverse charge), the line items, the envelope, the postal size class and zone and the typical delivery time for a page count, destination country and print options. Letters are printed and posted in Luxembourg, France, Belgium or Germany, so the sender can be anywhere in the world. Note: registered mail is international registered mail with tracking and signature on delivery; "certified" letters, Einschreiben, lettre recommandée and carta certificada mean this here (not a US certified-mail product). Works without sign-in. Set currency to get the total in USD, GBP or CHF (ECB rate plus currency margin). Does not cover email, fax, parcels or postcards.list_destinationsUse this when the user asks whether a letter can be posted to a country, or which countries can be reached. Without country: all destination countries with their postage zone. With country: that country's zone, the price of a 1-page standard and registered letter, and the typical delivery time. Works without sign-in. Letters only, no parcels.check_pdf_marginsUse this when the user has a PDF they want printed and posted and it should be checked first: verifies the page size (A4 or US Letter) and the required free margin on every side, and lists the pages that need changes. We print on the paper size uploaded (printed_on): A4 on A4, US Letter on US Letter (for a recipient outside the US, Canada and US territories the user may choose A4 instead when sending); a PDF mixing A4 and US Letter pages is printed on A4, its Letter pages centred at 100 % or scaled down slightly when content comes close to the edge (us_letter_note, pages[].scale_percent). Decide by compliant: all_pages_a4 is false for a US Letter PDF, which is printable. Accepts a public https URL or base64. The file is not stored and nothing is sent. Works without sign-in. To fix a failing PDF, upload it with upload_document and use fix_document_margins.compose_letterUse this when the user wants to write a new paper letter from text and post it, for example to cancel a contract, subscription or membership by letter, file a complaint or objection, or send a formal notice, by ordinary or registered mail. Renders an A4 letter (DIN 5008 layout: sender block with the user's own name and address, recipient, place and date, subject, body, closing, signature) that passes the print check, and creates a draft with the exact price. Nothing is sent or charged: show the user the draft and the total, ask for confirmation, then call send_letter. The sender can live in any country. Body supports paragraphs (blank line), '- ' bullets, '1. ' lists and **bold**. Needs the user's account.upload_documentUse this when the user already has a PDF (public https URL or base64) that should be printed and posted. Stores the file in the user's account, runs the print check (A4 or US Letter, free margins; printed_on says the paper: US Letter PDFs are printed on US Letter, a PDF mixing A4 and US Letter pages on A4, see us_letter_note; decide by compliant, as all_pages_a4 is false for a US Letter PDF) and returns document_id for create_letter. If the check fails, call fix_document_margins or ask the user for a corrected file. For a file on the user's own device, use create_upload_link instead. Sends nothing. Needs the user's account.fix_document_marginsUse this when an uploaded PDF fails the print check because content is too close to the edge or pages are neither A4 nor US Letter. mode "shrink" (default) scales the affected pages down slightly and centres them on their paper (US Letter for a US Letter PDF, else A4); nothing is lost. mode "crop" keeps pages at 100 % and removes everything inside the margin band, so that content is NOT printed (pages of other sizes are first fitted onto A4). The US Letter pages of a mixed PDF that already fit on A4 keep their placement. The original upload is kept; calling again with the other mode replaces the earlier fix. If content touches the edge, ask the user which mode they prefer and tell them what changed. Not possible once the letter is paid. Needs the user's account.create_upload_linkUse this when the user wants to post a PDF that is on their own device and cannot be passed as a URL or base64. Creates a private upload page (valid 60 minutes); give the URL to the user, and once they have uploaded, pass upload_id to create_letter. Sends nothing. Needs the user's account.create_letterUse this when the user has an uploaded PDF (document_id, or upload_id from create_upload_link) and a recipient address and wants it posted by ordinary or registered mail; registered mail is international registered mail with tracking and signature on delivery; "certified" letters, Einschreiben, lettre recommandée and carta certificada mean this here (not a US certified-mail product). Creates a draft with the exact total in the user's currency. Nothing is sent or charged; call send_letter only after the user confirms. Every envelope carries our company return address, so the user's own address belongs in the document. A US Letter PDF to a recipient outside the US, Canada and US territories needs the user's paper choice (paper_size, same price): without it the draft says paper_choice_required. Needs the user's account.send_letterUse this when the user has explicitly confirmed a specific draft letter (recipient, content and total price) and wants it printed and posted. Pays the letter from the user's prepaid credit and releases it to print; it can be cancelled with cancel_letter only until production starts. Only call this after that confirmation and after the user agreed to the Terms (https://printandmailcompany.com/en/legal/terms) and to printing starting immediately (which ends the consumer right of withdrawal once printed). If credit is too low, the result contains a payment link for the user; the assistant cannot pay. A US Letter PDF to a recipient outside the US, Canada and US territories needs paper_size (ask the user: shrink to A4, recommended, or keep US Letter; same price); without it the call fails with PAPER_CHOICE_REQUIRED and nothing is charged. Posts paper letters only: no email, fax or parcels. Needs the user's account.get_letterUse this when the user asks about a letter they created here: status (draft, paid, in_production, printed, posted, cancelled, returned), tracking number for registered mail, and price. Look up by letter_id or reference (PM-XXXXXX). Changes nothing. Needs the user's account.list_lettersUse this when the user wants to see their recent letters, optionally filtered by status. Returns status, recipient, price and tracking number per letter. Changes nothing. Needs the user's account.cancel_letterUse this when the user wants to stop a letter they created here: cancels a draft, or a paid letter that has not gone into production yet, and returns the amount to the user's credit. Letters already printed or posted cannot be recalled. This cancels our letter, not a contract the user has with someone else (for that, compose_letter writes the cancellation letter). Ask the user before cancelling. Needs the user's account.- +2 more on the listing page
