How do I connect Checkfront?

Before you connect

The login page asks for your Checkfront host, API key and API secret.

Host: the address you sign in to Checkfront at — your-company, your-company.checkfront.com, or a migrated …bookingplatform.app host. API key + secret: in Checkfront go to Manage → Developer → API, create a new application with the Token authentication type, and copy its API key and API secret. API access needs a paid Checkfront plan. Your credentials are used only to call the API on your behalf and to derive a private account id; they are never shown to anyone.

Claude claude.ai · Desktop

Open Customize → Connectors, then click + Add → Add custom connector.
Enter the name Checkfront and this URL, then click Add:
https://checkfront.usefulapi.io/mcp
Claude opens the login page: enter your Checkfront host, API key and API secret.
In a chat, click + → Connectors and turn on Checkfront.

Team and Enterprise: an Owner adds the connector for the organization first.

ChatGPT chatgpt.com

Open Plugins, click +, then Add custom MCP server.
Enter the name Checkfront and this URL, choose OAuth as the authentication, confirm the warning and create it:
https://checkfront.usefulapi.io/mcp
ChatGPT opens the login page: enter your Checkfront host, API key and API secret.
In Plugins, install Checkfront, then choose it in a chat.

No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.

Claude Code

Run this command, then run /mcp in Claude Code to log in:

claude mcp add --transport http checkfront https://checkfront.usefulapi.io/mcp

Cursor

Add to Cursor or add this to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "checkfront": {
      "url": "https://checkfront.usefulapi.io/mcp"
    }
  }
}

VS Code

Add to VS Code or add this to .vscode/mcp.json:

{
  "servers": {
    "checkfront": {
      "type": "http",
      "url": "https://checkfront.usefulapi.io/mcp"
    }
  }
}

Codex

Run these commands. The second one opens the login page:

codex mcp add checkfront --url https://checkfront.usefulapi.io/mcp

codex mcp login checkfront

Other clients

Windsurf, Cline, Zed and other MCP clients: add this URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser.

https://checkfront.usefulapi.io/mcp

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: the login page asks for your Checkfront host, API key and API secret. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.

Pricing

Plan	Price	Limit
Free	$0	50 tool calls / month
Proper user	$9/mo · $90/yr	10,000 tool calls / month
Pro+per user	$39/mo · $390/yr	100,000 tool calls / month

Each paid plan covers this Checkfront 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 support@usefulapi.io.

Read only · 14

Get company settingscheckfront_get_company
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.
List item categoriescheckfront_list_categories
List the inventory categories (e.g. Tours, Rentals, Accommodations) with their ids, names, display order and item counts.
List inventory items (optionally with availability and rates)checkfront_list_items
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.
Get an item (optionally with availability and rates)checkfront_get_item
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.
Get an availability calendarcheckfront_get_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?'.
List bookingscheckfront_list_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.
Get a bookingcheckfront_get_booking
Fetch extended information on one booking — status, dates, customer, form fields, line items and totals.
List booking notescheckfront_list_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.
Get the booking form fieldscheckfront_get_booking_form
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.
Get a booking session (cart)checkfront_get_booking_session
Read a booking session — the in-progress 'cart' — with its line items (keyed by line_id), dates, sub_total, tax, total and amount due.
Search customerscheckfront_search_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.
Get a customercheckfront_get_customer
Fetch one customer's contact details and their bookings (codes with created dates).
List events (seasons, specials, closures, discounts)checkfront_list_events
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.
List staff accountscheckfront_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.

Changes data · 6

Add items to a booking session (cart)checkfront_add_to_booking_session
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.
End or clear a booking sessioncheckfront_end_booking_session
Abandon a booking session: 'clear' empties its items, 'end' closes it. Releases the inventory it was holding; no booking is affected.
Create a bookingcheckfront_create_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.
Change a booking's statuscheckfront_update_booking_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.
Add a note to a bookingcheckfront_add_booking_note
Add a note to a booking, logged under the staff account the API acts on behalf of.
Check a booking in or outcheckfront_check_in_booking
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.

Your usefulapi plan · 4

Usage status (free-tier meter)checkfront_usage_status
Report the caller's current usage: the plan, calls used this month, the limit of the plan (the free monthly cap or the Pro fair use limit), remaining, and whether the limit is reached. Read-only; does not count against the meter.
Request a missing featurecheckfront_request_feature
Tell usefulapi that the user needs something the Checkfront tools cannot do yet (a missing tool, field or filter). Call it only when the user asks for something none of the tools can do, and tell the user that you send the request. Do not call it for errors or for normal requests. Do not include personal data, credentials or customer records. Stored with the product name and the client type (for example Claude or Cursor), without the user's account. At most 5 requests per day. Does not count against the meter.
Upgrade to Pro or Pro+checkfront_upgrade
Get a paid plan for Checkfront (the free tier caps monthly usage). Pro: 10,000 tool calls a month, for normal use — plan "monthly" ($9/month) or "yearly" ($90/year, 2 months free). Pro+: 100,000 tool calls a month, for automations and heavy use — plan "plus" ($39/month) or "plus_yearly" ($390/year). Without a plan it returns both Pro and Pro+, each with a payment link, for the user to choose; with a plan, one link. An existing Pro subscription changes to Pro+ in place: call without confirm first, as the reply states the exact charge for this account (the price difference for the rest of the period, or in a free Pro trial the full Pro+ price, as the trial ends); then call with confirm: true. Cancel any time: the plan then runs to the end of the paid period, so it also suits a one-time job. A link opens Stripe Checkout in the browser; after payment the account upgrades automatically. Does not count against the meter.
Cancel the Pro subscriptioncheckfront_cancel_subscription
Cancel the caller's Checkfront Pro subscription at the end of the paid period (no refund for the current period; Pro continues until then, then the free tier applies). Requires confirm: true. Run checkfront_upgrade later to undo the cancel before the period ends. Does not count against the meter.

FAQ

What can I do with Checkfront in Claude or ChatGPT?

Check availability and rates for a date. List the bookings for a period. Look up a customer and their bookings. Create a booking for a customer. Check in a guest or change a booking status. Read booking notes or add one. See what you can do for the details.

Is this an official Checkfront product?

No. usefulapi is an independent service. It is not affiliated with or endorsed by Checkfront. The server calls the Checkfront API with your own Checkfront access, so it sees only the data that your account can see.

Can I connect Checkfront to Claude or ChatGPT?

Yes. In Claude, add this server's URL as a custom connector. In ChatGPT, add it as a custom MCP server in Plugins. Then log in once. Cursor, VS Code, Claude Code and Codex work too. See the setup steps.

What do I need to connect?

The login page asks for your Checkfront host, API key and API secret. See Before you connect for where to find them.

Do I put my Checkfront key or an Authorization header in the client config?

No. 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: the login page asks for your Checkfront host, API key and API secret. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.

How do you keep my Checkfront credentials?

The login stores them encrypted in the authorization grant of your connection. The server uses them to call the Checkfront API for you and to derive a private account id for usage metering. usefulapi does not show them on any page or in any reply. To stop all access, remove the connector and change or delete these credentials in Checkfront.

Can the AI change my Checkfront data?

Yes, if you approve it. 6 of the 20 Checkfront tools can create or change data. The other 14 are marked read-only. Most MCP clients ask you to approve a tool call before it runs.

What does it cost?

The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with 10,000 tool calls / month. Pro+ costs $39/mo or $390/yr, with 100,000 tool calls / month. Each subscription covers this Checkfront server only. Cancel any time: your paid plan then runs to the end of the paid period. Run checkfront_usage_status to see how many calls you used.

How do I subscribe or cancel?

Ask the 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+. After you confirm, your existing subscription changes in place, keeps its billing interval and charges the price difference for the rest of the period immediately. To cancel, run checkfront_cancel_subscription. Your paid plan continues to the end of the paid period.

What if a Checkfront tool that I need is missing?

Tell the AI what you wanted to do. It can send the request with checkfront_request_feature. We store the text with the server name, the type of AI client and the tool you tried, not with your account, and read every request when we plan new tools. You can send up to 5 requests per day.

Which AI clients can I use?

Any client that supports remote MCP servers (Streamable HTTP) with OAuth login: Claude (web and desktop), Claude Code, ChatGPT, Codex, Cursor, VS Code, Windsurf and others.

This is a Model Context Protocol endpoint — meant to be connected from an AI client, not opened in a browser. An invalid_token response at the URL is the auth gate working as designed; clients authenticate automatically.
