Check Checkfront availability and rates, and manage booking sessions, bookings, customers and notes.
The publisher's own server: Ably MCP by usefulapi
Hosted Checkfront MCP server that lets an assistant check availability and rates, manage booking sessions and bookings, and look up customers.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/io.usefulapi%2Fcheckfront/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Add this to your client's mcpServers config.

}Use Checkfront from Claude, Cursor, or any MCP client — check item availability and rates, build booking sessions, create bookings, change status, and read customers and events. Hosted, no local install: connect with your own Checkfront credentials.
Live endpoint: https://checkfront.usefulapi.io/mcp · Homepage: https://usefulapi.io/checkfront
https://checkfront.usefulapi.io/mcp.claude mcp add --transport http checkfront https://checkfront.usefulapi.io/mcp, then run /mcp to log in.Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Checkfront credentials.
Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/checkfront/
On first connect you'll provide your Checkfront host, API key and API secret (Manage → Developer → API; paid plan). They're validated, stored per-user, and scoped to you — no keys in config files.
read tools are read-only; write tools mutate data (clients should confirm them); meta tools report usage, manage your subscription or send a feature request.
Each paid plan covers this server only. Ask your AI to run checkfront_upgrade and choose Pro or Pro+, billed monthly or yearly (it returns a Stripe Checkout link). If you already have Pro, ask to change it to Pro+. The change requires your confirmation, keeps your billing interval and charges the price difference for the rest of the period immediately. Cancel any time with checkfront_cancel_subscription: your paid plan continues to the end of the paid period, with no refund for the current period, and asking to resume the same plan with checkfront_upgrade before then undoes the cancel. Or write to [email protected].

Get company settings
Fetch 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.
Takes no parameters.
List item categories
List the inventory categories (e.g. Tours, Rentals, Accommodations) with their ids, names, display order and item counts. Checkfront: GET /api/3.0/category.
Takes no parameters.
List inventory items (optionally with availability and rates)
List 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_session needs to book the item. Checkfront: GET /api/3.0/item.
dateparamrulesitem_idkeywordend_dateend_timepackagesavailablestart_datestart_timecategory_id+1 moreGet an item (optionally with availability and rates)
Fetch 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. Checkfront: GET /api/3.0/item/{item_id}.
dateparamrulesitem_idrequiredend_dateend_timepackagesstart_datestart_timediscount_codeGet an availability calendar
Day-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.
end_dateitem_idsstart_datecategory_idList bookings
List 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 pages exist. Checkfront: GET /api/3.0/booking/index.
pagelimititem_idend_datestatus_idpartner_idstart_datecustomer_idcreated_datelast_modifiedcustomer_emailGet a booking
Fetch extended information on one booking — status, dates, customer, form fields, line items and totals. Checkfront: GET /api/3.0/booking/{booking_id}.
booking_idrequiredList booking notes
List 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.
dateGet the booking form fields
Fetch 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.
Takes no parameters.
Get a booking session (cart)
Read 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.
session_idrequiredSearch customers
Look 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.
customer_idcustomer_namecustomer_emailcustomer_phoneGet a customer
Fetch one customer's contact details and their bookings (codes with created dates). Checkfront: GET /api/3.0/customer/{customer_id}.
customer_idrequiredList events (seasons, specials, closures, discounts)
List 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.
Takes no parameters.
List staff accounts
List 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.
Takes no parameters.
Add items to a booking session (cart)
Start 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 session is open; NOTHING is booked until checkfront_create_booking. Returns the session_id to reuse. Checkfront: POST /api/3.0/booking/session.
slipalterline_idsession_idEnd or clear a booking session
Abandon 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.
actionsession_idrequiredCreate a booking
Commit 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 inventory and may notify the customer; change it later with checkfront_update_booking_status. Returns the new booking's ids and any invoice/payment URL. Checkfront: POST /api/3.0/booking/create.
formrequiredslipsession_idChange a booking's status
Set 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. Checkfront: POST /api/3.0/booking/{booking_id}/update.
notifystatus_idrequiredbooking_idrequiredAdd a note to a booking
Add 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.
bodyrequiredbooking_idrequiredCheck a booking in or out
Mark 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.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
