Read pretix events, tickets and orders; check attendees in or out with your own account. Hosted by usefulapi: connect it to Claude, ChatGPT, Cursor or any MCP client.
Turn on the pretix connector, then ask in plain words. The AI picks the tools.
For event organizers who manage tickets and attendee check-ins with pretix.
List upcoming events, inspect their ticket types and check the remaining quota before answering availability questions.
Find orders by event or organizer, then inspect an order and its attendee tickets to answer booking questions.
Review check-in totals, attendee check-in history and waiting list entries for an event.
Find the attendee on a check-in list and record an entry or exit scan when requested. Pretix applies its ticket validation rules.
Changes dataYou sign in with your pretix account and approve the access (OAuth). You do not need an API key.
Only accounts on the hosted pretix service are supported. Allow read, write and profile access; the profile identifies your account, and write access enables attendee check-in when you explicitly request it. This server does not create orders, take payments or publish events. Attendee information passes to the AI client you choose. You can revoke access in pretix user settings → Authorized applications. Changing your pretix login email changes this server's billing identity.
Team and Enterprise: an Owner adds the connector for the organization first.
No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.
Run this command, then run /mcp in Claude Code to log in:
Add to Cursor or add this to ~/.cursor/mcp.json:
{
"mcpServers": {
"pretix": {
"url": "https://pretix.usefulapi.io/mcp"
}
}
} Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"pretix": {
"type": "http",
"url": "https://pretix.usefulapi.io/mcp"
}
}
} Run these commands. The second one opens the login page:
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.
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: you sign in with your pretix account. 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.
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 50 tool calls / month |
| Proper pretix user | $9/mo · $90/yr | 10,000 tool calls / month |
| Pro+per pretix user | $39/mo · $390/yr | 100,000 tool calls / month |
Each paid plan covers this pretix server only. Ask your AI to run pretix_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 pretix_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 pretix_upgrade before then undoes the cancel. Or write to [email protected].

No. usefulapi is an independent service. It is not affiliated with or endorsed by pretix. The server calls the pretix API with your own pretix access, so it sees only the data that your account can see.
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.
A pretix account. You sign in to pretix and approve the access. You do not need an API key.
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: you sign in with your pretix account. 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.
The login stores them encrypted in the authorization grant of your connection. The server uses them to call the pretix 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. You can revoke the access in pretix at any time.
Yes, if you approve it. 1 of the 18 pretix tools can create or change data. The other 17 are marked read-only. Most MCP clients ask you to approve a tool call before it runs.
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 pretix server only. Cancel any time: your paid plan then runs to the end of the paid period. Run pretix_usage_status to see how many calls you used.
Ask the AI to run pretix_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 pretix_cancel_subscription. Your paid plan continues to the end of the paid period.
Tell the AI what you wanted to do. It can send the request with pretix_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.
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.
