PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What it can do

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_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. Checkfront: GET /api/3.0/company.

  • checkfront_list_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.

  • 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

  • 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. Ch

  • checkfront_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?'. Checkfront: GET /api/3.0/item/{item_id}/cal or GET /api/3.0/item/cal.

  • checkfront_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 p

  • checkfront_get_booking

    Fetch 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_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.

  • checkfront_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. Checkfront: GET /api/3.0/booking/form.

  • 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. Checkfront: GET /api/3.0/booking/session.

  • checkfront_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. Checkfront: GET /api/3.0/customer.

  • checkfront_get_customer

    Fetch one customer's contact details and their bookings (codes with created dates). Checkfront: GET /api/3.0/customer/{customer_id}.

  • 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. Checkfront: GET /api/3.0/event.

  • checkfront_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.

  • 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 sess

  • checkfront_end_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.

  • checkfront_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

  • checkfront_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. Checkfron

  • checkfront_add_booking_note

    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.

  • checkfront_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. Checkfront: POST /api/3.0/booking/{booking_id}/checkin or /checkout.

Common questions

Is Checkfront MCP by usefulapi safe?

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.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.35.3) reached the registry yesterday.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Checkfront MCP by usefulapi

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

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://checkfront.usefulapi.io/mcp.
  • Claude Code: claude mcp add --transport http checkfront https://checkfront.usefulapi.io/mcp, then run /mcp to log in.
  • VS Code: Add to VS Code.
  • Cursor and other clients: add the URL as a remote MCP server:
{

"mcpServers": { "checkfront": { "url": "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, 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.
