Anlyon alternative

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.

Tools

Grouped by what each tool does, most consequential first. Open one for its reasons and full description; descriptions are the publisher's own words.

    Why it is in this group

    • The input takes a statement or command to run (input.script), which can change anything it can reach.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

    Findings

    • Warn

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

      What this check looks for
    Description, as the server wrote it
    Checks a VXLScript game the way the VXLVERSE editor does: it builds, someone is in it, it holds nothing unsafe or personal, and the player can reach the win. Returns the errors to fix (the first one first), or ok with a direct link that opens the game in the editor. Stores nothing; call it again after each fix.

    Annotations the server declares

    • title: Check the game
    • readOnlyHint: true
    • destructiveHint: false
    • openWorldHint: false

  • get_vxlscript_guideReturns the complete guide to VXLScript, the plain-text language every VXLVERSE game is written in: the one-screen card, the full reference and worked examples.No findings

    Why it is in this group

    • The name "get_vxlscript_guide" says "get": a word for reading.
    Description, as the server wrote it
    Returns the complete guide to VXLScript, the plain-text language every VXLVERSE game is written in: the one-screen card, the full reference and worked examples. Use it once before writing a game and follow it exactly; never invent a command it does not list. Reads nothing from the user and changes nothing.

    Annotations the server declares

    • title: Learn VXLScript
    • readOnlyHint: true
    • destructiveHint: false
    • openWorldHint: false

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.

All changes to this server

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__vxlverse__get_vxlscript_guide"
    ],
    "ask": [

      "mcp__vxlverse__create_game_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 vxlverse. 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.
