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.
pretix_list_organizersList the organizer accounts this API token can access (slug, name, public URL). A team token sees its own organizer. GET /organizers/.
pretix_get_organizerOne organizer account: slug, name, public URL. GET /organizers/{organizer}/.
pretix_list_eventsList the events of an organizer (name, slug, dates, live/test mode, currency, location, whether it is an event series). Filter by search text, live state or date. GET /organizers/{organizer}/events/.
pretix_get_eventOne event in full: name, dates, location, currency, live/test mode, presale window, meta data, enabled plugins. GET /organizers/{organizer}/events/{event}/.
pretix_list_subeventsList the dates (sub-events) of an event series, for one event or across all series of the organizer. Each has id, name, dates, location, presale window and price overrides. GET /organizers/{organizer}/events/{event}/subevents/ or /organizers/{organizer}/subevents/.
pretix_get_subeventOne date (sub-event) of an event series. GET /organizers/{organizer}/events/{event}/subevents/{id}/.
pretix_list_itemsList the products (ticket types, merchandise) of an event with id, name, default price, tax, active flag, category and variations. GET /organizers/{organizer}/events/{event}/items/.
pretix_get_itemOne product with its variations, add-ons and bundles. GET /organizers/{organizer}/events/{event}/items/{id}/.
pretix_list_quotasList the quotas (capacity pools) of an event: size, the products they cover, closed state and, with with_availability, how many are still available. GET /organizers/{organizer}/events/{event}/quotas/.
pretix_get_quota_availabilityHow much of a quota is left: available, available_number, total_size and what is using it (pending and paid orders, cart positions, blocking vouchers, waiting list). Values can lag slightly. GET /organizers/{organizer}/events/{event}/quotas/{id}/availability/.
pretix_list_ordersList orders of one event, or of all events of the organizer when no event is given: code, status, email, total, dates, positions, payments, invoice address. Contains customer personal data. Order secrets, order links and payment details are removed. GET /organizers/{organizer}/ev
pretix_get_orderOne order by its code (e.g. ABC12): status, customer email and phone, total, positions (tickets), fees, payments, refunds as recorded, invoice address, check-in flags. Contains customer personal data. Secrets, order link and payment details are removed. GET /organizers/{organizer
pretix_list_order_positionsList the individual tickets (order positions) of one event, or of all events of the organizer when no event is given: attendee name and email, product, variation, price, order code, check-ins, answers. Contains attendee personal data. Ticket secrets are removed. GET /organizers/{
pretix_list_checkin_listsList the check-in lists of an event (id, name, the products they admit, event series date, rule settings). Use the list id for check-in status, attendee lists and check-in. GET /organizers/{organizer}/events/{event}/checkinlists/.
pretix_get_checkin_list_statusLive check-in numbers of a check-in list: how many tickets exist, how many are checked in, how many are inside now, broken down per product and variation. GET /organizers/{organizer}/events/{event}/checkinlists/{id}/status/.
pretix_list_checkin_list_positionsThe attendee list of a check-in list: tickets with attendee name, product, order code, check-in history and whether the ticket needs attention. Contains attendee personal data. Ticket secrets are removed; check in by position id. GET /organizers/{organizer}/events/{event}/checkin
pretix_list_waiting_listList the waiting list entries of an event: who waits for which product, since when, and whether a voucher was already sent. Contains personal data (name, email, phone). Read-only: no voucher is sent. GET /organizers/{organizer}/events/{event}/waitinglistentries/.
pretix_checkin_positionWRITE: check one ticket in (or out) on a check-in list. Records a real check-in in pretix and cannot be undone from here. Identify the ticket by position_id (from pretix_list_checkin_list_positions) or by ticket_secret (the scanned QR code content). pretix applies its own rules:

Common questions
Is pretix 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 (1.7.3) 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?
In the same category: Spree Commerce: open-source B2B and marketplace ecommerce, Stripe MCP, MCP Cn Commerce

pretix MCP by usefulapi
Read events, products, quotas, orders, tickets, check-in lists and waiting lists from the hosted pretix service. Check attendees in or out when requested.
Live endpoint: https://pretix.usefulapi.io/mcp · Homepage: https://usefulapi.io/pretix/
Connect
- Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste
https://pretix.usefulapi.io/mcp. - Claude Code:
claude mcp add --transport http pretix https://pretix.usefulapi.io/mcp, then run/mcpto log in. - VS Code: Add to VS Code.
- Cursor and other clients: add the URL as a remote MCP server:
{
"mcpServers": { "pretix": { "url": "https://pretix.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 you sign in with your pretix account.
Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/pretix/
Sign in through pretix OAuth and approve read, write and profile permissions. Only hosted pretix.eu accounts are supported. Your pretix permissions determine which organizers you can access. This server does not create orders, take payments or publish events.
Attendee data passes to your chosen AI client. Revoke access under pretix user settings → Authorized applications. Billing is per pretix user, identified by the normalized login email; changing that email changes the billing identity.
