2 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.

    Description, as the server wrote it
    For an AP exam, year and score from 1 to 5, returns the percent of test takers who scored lower, the same and higher, and the midpoint percentile rank, from the official College Board distribution. Uses exact counts for 2024 and 2025 and the published whole percents for 2026.

      What this check looks for
    Description, as the server wrote it
    Converts multiple-choice correct answers and free-response points into a weighted composite and an estimated AP score, using the scoring worksheet and conversion chart College Board printed in its official practice exams. Only for the 7 exams with such a worksheet: AP Calculus AB (2012), AP Biology (2013), AP Statistics (2012), AP World History (2013), AP Psychology (2012), AP Macroeconomics (2012), AP Microeconomics (2012). Cut scores are never invented; other exams return an error.

Includes the May 2026 results from the College Board 2026 AP Score Distributions page, which are newer than most model training data. Shows the 2024/2025/2026 history for the exam.

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 private-data or untrusted-input or outbound.

Reads private data0
Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write0
Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
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.

Findings

Matches of fixed checks, with the text they matched.

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.

    "allow": [
      "mcp__ap-score-distributions__get_ap_score_distribution",

}

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 ap-score-distributions. Review it before you use it.

Pin

Keep the decision: fail CI when the tools change, follow every change, or show a badge.

Pin in CI

Fail a build when the tools you reviewed are not the tools the server serves today.
