## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 46/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not yet verified: we couldn't confirm whether this endpoint requires it.
  - HTTPS enforcement could not be verified: the plaintext port redirected somewhere other than https, so enforcement is unproven.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 0/100
  - Transport check failed: declared streamable-http, but the endpoint redirected instead of responding directly.
- **Schema Quality & AI Usability**: 0/100
  - Schema not yet verified: we couldn't read the endpoint's schema, or could read only part of its tool list.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 0/100
  - Tool coverage not yet verified: we couldn't read the endpoint's tools, or could read only part of the list.
- **Tool Safety**: 0/100
  - Tool safety not yet verified: we couldn't read the endpoint's tools, or could read only part of the list.
- **Capabilities**: 0/100
  - Capabilities not yet verified: we couldn't read the endpoint's capabilities.

**Unverified: 5 categories.** Categories scored 0 because we could not verify them: authentication we do not have, an unreachable endpoint, or not enough scan history. We only credit what we can confirm.

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: the call is refused for unpaid, canceled, blocked, already-used or wrong-product tickets (the reason is returned), and it never forces a check-in. A required question that is unanswered comes back as incomplete with the question list; answer it with `answers`. One ticket per call. POST /organizers/{organizer}/events/{event}/checkinlists/{list}/positions/{id}/redeem/.

Input parameters:

- `answers` (object): Answers to required questions: { "<question id>": "<answer>" }. For choice questions use comma-separated option ids.
- `checkin_list_id` (integer, required): Check-in list id.
- `event` (string, required): Event slug (see pretix_list_events).
- `nonce` (string): Idempotency key: a retry with the same nonce does not check in twice. Generated when omitted.
- `organizer` (string): Organizer slug (see pretix_list_organizers). Optional when the login token sees exactly one organizer.
- `position_id` (integer): Ticket (order position) id from pretix_list_checkin_list_positions. Give this or ticket_secret.
- `ticket_secret` (string): The scanned ticket code (secret). Give this or position_id.
- `type` (string): entry (default) or exit.

## Common questions

### What is the pretix MCP by usefulapi server?

pretix MCP by usefulapi is listed in the public MCP registry as io.usefulapi/pretix. Read pretix events, tickets and orders; check attendees in or out with your own account. This page covers its hosted endpoint (https://pretix.usefulapi.io/mcp).

### Is the pretix MCP by usefulapi server safe to use?

pretix MCP by usefulapi scores 18 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the pretix MCP by usefulapi server expose?

pretix MCP by usefulapi exposes 18 tools: pretix_list_organizers, pretix_get_organizer, pretix_list_events, pretix_get_event, pretix_list_subevents, and 13 more. Their descriptions and schemas cost roughly 3,597 tokens of context every time the server is loaded.

### Does the pretix MCP by usefulapi server require authentication?

Its publisher declares no required credentials for pretix MCP by usefulapi. We have not been able to confirm that against the live endpoint, and a server can require authorisation without declaring it here.

### Is the pretix MCP by usefulapi server still maintained?

pretix MCP by usefulapi is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What did VerifyMCP test on the pretix MCP by usefulapi server?

VerifyMCP ran 4 checks on pretix MCP by usefulapi, covering TLS certificate, HSTS header, DNSSEC and Transport. 7 items could not be completed, a gap on our side rather than a finding about pretix MCP by usefulapi: Authorization, HTTPS, Schema quality, Stability and 3 more. 5 categories score 0 for that reason, because we only credit what we can confirm. Supply Chain Security and Provenance & Transparency do not apply to a hosted endpoint, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
