With Anlyon

2 tools here change things. Govern them.

Anlyon lists the tools and adopts none.
Each tool you adopt gets approvals and receipts.
Your agent never holds the key.

Govern this server →

A tool your agent calls directly is not routed through Anlyon and is not governed by it. anlyon.dev only lists and labels, and these labels are the same either way.

What the UK Data: Quiz questions MCP server can do

The UK Data: Quiz questions MCP server is published by reliness.co.uk, a domain the MCP Registry verified. It has 4 tools. It can create or change data (2 tools: trivia_questions and trivia_true_false), but cannot delete data. 2 tools only read.

2 tools read private data (trivia_categories and trivia_question_count); 4 tools bring in text other people can write (trivia_questions, trivia_true_false, trivia_categories and 1 more).

None of the fixed checks matched anything in its tool definitions. That is not a safety guarantee.

Its remote endpoint lists its tools without sign-in.

Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
What it can reach
- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
Description, as the server wrote it
Multiple-choice quiz questions, each with the correct answer, three wrong answers and the four options in a fixed A-D order with the right letter, from the community-written and moderator-reviewed Open Trivia Database (CC BY-SA 4.0). Pick a category (e.g. sports, geography, film, history) and difficulty, or mix. Good for pub quiz rounds, classroom quizzes and team events. Questions are drawn at random each call and the bank is mostly English-language general trivia; it is not a curriculum-aligned or UK-specific source, and a few answers may date. (cost: 1 credit)

Description, as the server wrote it
True-or-false quiz statements with the correct answer, from the community-written and moderator-reviewed Open Trivia Database (CC BY-SA 4.0), by category and difficulty or mixed. Handy for quick rounds, icebreakers and classroom warm-ups. Statements are drawn at random each call; the true/false bank is smaller than the multiple-choice one, so narrow category plus difficulty combinations may have only a handful. (cost: 1 credit)

How many reviewed questions the Open Trivia Database holds in one category, split into easy, medium and hard, so a quiz round can be planned without asking for more questions than exist (some categories hold only a few dozen hard questions).

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Exfil surface

Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.

No private-data, untrusted-input, outbound path in this server alone: no tool is tagged outbound.

Reads private data2: Reads files, mail, messages, databases, secrets, calendars or repositories.; trivia_categories
trivia_question_count
Reads text others write4: Brings in text someone else can write: web pages, inbound email, messages, issues and comments.; trivia_categories
trivia_question_count
trivia_questions
trivia_true_false
Can send data out0: Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.

Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.

Remote posture

What anyone on the internet sees at the remote endpoint: an anonymous initialize and tools/list, and the public OAuth metadata.

The endpoint served tools/list without credentials, and the list has 2 tools that change things (2 write). Whether a call also works without credentials was not tested: tools are never called.

What this check looks for

Findings

Matches of fixed checks, with the text they matched.

No check matched anything in these tool definitions. That is not a safety guarantee.

History

Changes to its tool definitions and to its remote endpoint, newest first.

No change seen yet. Its tools are rescanned every day, and a remote endpoint is looked at once a week.

Claude Code permissions

Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.

  "permissions": {
    "allow": [

}

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as quiz-trivia. Review it before you use it.
