Description from the maker (original English)
Check Checkfront availability and rates, and manage booking sessions, bookings, customers and notes.
These three are never merged into one score: opinions, measurements and popularity are different things.

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.
checkfront_get_companyFetch the connected Checkfront account's company configuration — name, URL, plan, currency, timezone, locale and date/time formats. A cheap way to confirm the host and credentials work. Checkfront: GET /api/3.0/company.
checkfront_list_categoriesList the inventory categories (e.g. Tours, Rentals, Accommodations) with their ids, names, display order and item counts. Checkfront: GET /api/3.0/category.
checkfront_list_itemsList the enabled inventory items (tours, activities, rentals, rooms). With NO dates this is the plain catalogue. Pass start_date (and end_date / param quantities) to get a RATED response: per-item availability, pricing and a SLIP token — the SLIP is what checkfront_add_to_booking
checkfront_get_itemFetch one inventory item's details. Pass start_date / end_date and param quantities (e.g. {"adults": 2}) for a RATED response with availability (rate.status, rate.available), the price breakdown and the SLIP used to book it. For parent/child grouped items, rate the CHILD item. Ch
checkfront_get_availability_calendarDay-by-day available inventory over a date range — for one item (item_ids with a single id), several items, or a whole category. Use it to answer 'which days next month still have space?'. Checkfront: GET /api/3.0/item/{item_id}/cal or GET /api/3.0/item/cal.
checkfront_list_bookingsList bookings, newest filters first — by status, customer, dates, item or partner. Each row has the booking code, status, totals (total, tax_total, paid_total), customer name/email, summary and date_desc. Paged (default 100/page); the response's request.pages tells you how many p
checkfront_get_bookingFetch extended information on one booking — status, dates, customer, form fields, line items and totals. Checkfront: GET /api/3.0/booking/{booking_id}.
checkfront_list_booking_notesList the notes left on bookings across the account (default: the past 30 days), each with its booking code, author account id (0 = customer), date, body and whether it is private. Checkfront: GET /api/3.0/booking/notes.
checkfront_get_booking_formFetch the customer-details form for a booking (booking_form_ui): every field id (customer_name, customer_email, …), its label, type and whether it is required. Call this before checkfront_create_booking to know which `form` fields to send. Checkfront: GET /api/3.0/booking/form.
checkfront_get_booking_sessionRead a booking session — the in-progress 'cart' — with its line items (keyed by line_id), dates, sub_total, tax, total and amount due. Checkfront: GET /api/3.0/booking/session.
checkfront_search_customersLook up customers by exact email, full name or phone number (exact matches; non-unique fields such as name can return several). Results are in the `customers` object. Checkfront: GET /api/3.0/customer.
checkfront_get_customerFetch one customer's contact details and their bookings (codes with created dates). Checkfront: GET /api/3.0/customer/{customer_id}.
checkfront_list_eventsList the date-based events that change price or availability — seasonal rates (SE), specials (SP), discounts (DC), closures (status U) — with their dates, recurrence, pricing rule and the items/categories they apply to. Checkfront: GET /api/3.0/event.
checkfront_list_staff_accountsList the staff (and partner) accounts on the Checkfront account — ids, names, emails, login ids and whether enabled. The account_id is what CHECKFRONT_ON_BEHALF takes. Checkfront: GET /api/3.0/account.
checkfront_add_to_booking_sessionStart or modify a booking session: add one or more SLIPs (from a rated checkfront_get_item / checkfront_list_items call), replace a line with a new SLIP (line_id + slip), or alter lines (quantity, 'remove', 'optin'/'optout' for package add-ons). Holds the inventory while the sess
checkfront_end_booking_sessionAbandon a booking session: 'clear' empties its items, 'end' closes it. Releases the inventory it was holding; no booking is affected. Checkfront: POST /api/3.0/booking/session/clear or /booking/session/end.
checkfront_create_bookingCommit a booking: from a session_id (built with checkfront_add_to_booking_session) or directly from SLIPs, plus the customer form fields (see checkfront_get_booking_form for which are required — typically customer_name and customer_email). Creates a real reservation that consumes
checkfront_update_booking_statusSet a booking's status — e.g. confirm a pending booking (PAID/PART), put it on HOLD or WAIT(list), or cancel it (VOID/STOP). Reversible: set it back to the previous status the same way. Does NOT record a payment. Optionally triggers the account's customer notifications. Checkfron
checkfront_add_booking_noteAdd a note to a booking, logged under the staff account the API acts on behalf of. Checkfront: POST /api/3.0/booking/{booking_id}/note.
checkfront_check_in_bookingMark a guest as arrived (check in) or departed (check out). Checkfront adds a note under the acting account. VOID and cancelled bookings cannot be checked in or out. Checkfront: POST /api/3.0/booking/{booking_id}/checkin or /checkout.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
