Anlyon alternative

3 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.

Changes things 3Claude Code: ask
  • list_books_checksSTART HERE for a books health check.1 finding

    Why it is in this group

    • The name "list_books_checks" says "list": a word for reading.
    • The description's first verb is "start": a word for a change.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

    Findings

    • Warn

      The server marks "list_books_checks" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

      annotations: {"readOnlyHint":true,"idempotentHint":true,"openWorldHint":false}; The name "list_books_checks" says "list": a word for reading.

      What this check looks for
    Description, as the server wrote it
    START HERE for a books health check. Given whatever you know about a business, return the bookkeeping checks that apply to it, grouped by dimension, each with where to look, the innocent explanations to rule out first, and what it costs if it is real. Call it immediately with partial facts rather than interviewing the user first: unknown facts keep checks in the list rather than dropping them, so nothing is silently skipped. Cash-basis businesses correctly get a shorter list. This never says whether books are correct, only what to look at.

      What this check looks for
    Description, as the server wrote it
    START HERE. Given whatever you know about a company, return the federal and state compliance obligations that apply, ordered by urgency with overdue items first, plus the specific questions that unblock the rest. Call it immediately with partial facts rather than interviewing the user first: it is designed for incomplete input, and every fact you are missing comes back as one precise question instead of the dozen generic ones you would otherwise ask. Then answer those and call it again. Defaults to a short actionable view; relay it roughly as written rather than expanding it into an essay, and pass detail='full' only when the user asks for evidence tiers and remediation detail. Covers US federal plus CA, CO, DE, FL, GA, IL, MA, NJ, NY, PA, TX and WA; every other state is reported honestly as not yet covered. This never tells you whether you are compliant, only what to check.

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.

    Description, as the server wrote it
    Score a books health check from the statuses you actually evidenced. Returns the weighted score, the band, a per-dimension breakdown and the findings ranked worst first. Two rules a plain average does not give you: a confirmed critical caps the grade, and the band is WITHHELD entirely when too little was evidenced, because a flattering number off three checks is the part people quote. Report the withheld state rather than supplying a band yourself.

    Description, as the server wrote it
    Refinement step, NOT the place to start: call list_compliance_obligations first, then call this to narrow what is still genuinely open. Returns the facts that flip an answer, such as whether an employer of record is the legal employer. Pass every fact you already know and it returns only what those facts leave unsettled. These are things for YOU to look up in the user's own documents. They are not a questionnaire to send the user.

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 outbound.

Reads private data0
Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write2
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.

    The endpoint served tools/list without credentials, and the list has 3 tools that change things (3 write). Whether a call also works without credentials was not tested: tools are never called.

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 compliance. Review it before you use it.
