Anlyon alternative

1 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
    This year's programs with session dates and tuition, next year's under `nextYear` once its dates are posted, the online offerings, and the policy FAQ (payment deadlines, cancellations). Session dates carry no year: take it from `year` or `nextYear.year`. Some of this year's sessions may be over; get_enrollment_form lists only weeks still ahead. Read-only. No seat counts.

    Why it is in this group

    • The name "get_enrollment_form" says "get": a word for reading.
    Description, as the server wrote it
    Everything needed to interview someone for one program's enrollment form: the upcoming weeks on the form (productId, dates, pay-in-full / deposit prices, whether enrollment is open), the questions you may prefill (key, what to ask, kind, choices, required), who must fill it in, and what they still have to do on the form themselves. Read-only. Programs: sonata = The Sonatas (adult week-long camps); intermezzo = The Intermezzi (adult long weekends); capriccio = The Capriccios & Suites (adult); sonatina = Summer Sonatina (children); virtual = Virtual courses and camps.

    Annotations the server declares

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.

1 warn
  • Warnbuild_enrollment_link

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

    Matched text

    annotations: {"readOnlyHint":true,"openWorldHint":false}; The name "build_enrollment_link" says "link": a word for a change.

    What this check looks for

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.

Run in a terminal.

Claude Code permissions

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

.claude/settings.json
{
  "permissions": {
    "allow": [
      "mcp__sonatina__get_catalog",
      "mcp__sonatina__get_enrollment_form"
    ],
    "ask": [
      "mcp__sonatina__build_enrollment_link"
    ],
    "deny": []
  }
}

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 sonatina. 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.
