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.

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.

render_wireframeCheck tsquare wireframe text and render it.No findings
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.
Description, as the server wrote it
Check tsquare wireframe text and render it. Returns a PNG of the board so you can see it, or the problems by line number (with the valid options) if the text isn't valid. Fix every problem and call it again.
Annotations the server declares
- readOnlyHint: true
- openWorldHint: false
share_wireframeLinks for valid tsquare wireframe text, the same kinds as the playground's Copy link menu: a share link to edit it in the playground, image links (SVG, PNG), Markdown and HTML.1 finding
Why it is in this group
- The description's first verb is "link": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

  The server marks "share_wireframe" 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
Links for valid tsquare wireframe text, the same kinds as the playground's Copy link menu: a share link to edit it in the playground, image links (SVG, PNG), Markdown and HTML. Ask only for the links the user needs (default: an SVG image link and the share link). Each link contains the whole wireframe text (compressed), so anyone with a link can read it.
Annotations the server declares
- readOnlyHint: true
- openWorldHint: false
wireframe_guideHow to write a tsquare wireframe: the text format, the rules, a worked example and every component with its props.No findings
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.
Description, as the server wrote it
How to write a tsquare wireframe: the text format, the rules, a worked example and every component with its props. Call it once before writing your first wireframe.
Annotations the server declares
- readOnlyHint: true
- 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.

Remote posture

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

Tools listed without sign-in

Looked at Nov 4, 2026, 02:19 UTC, unchanged since Nov 4, 2026. No credentials were sent and no tool was called. What is looked at.

Reachable: yes
HTTP status of an anonymous initialize: 200

Tools that change things, listed without credentials: 3

WarnThe whole server
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.
Matched text
https://tsquare.dev/mcp: tools/list returned 3 tools to an anonymous client, including wireframe_guide (write), render_wireframe (write), share_wireframe (write)

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": [],
    "ask": [
      "mcp__tsquare__wireframe_guide",
      "mcp__tsquare__render_wireframe",
      "mcp__tsquare__share_wireframe"
    ],
    "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 tsquare. Review it before you use it.

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.
