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.

  • html_to_pdfConvert an HTML document up to 4 MB to a PDF with Chromium (Gotenberg).Reads text others write1 finding

    Why it is in this group

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

    What it can reach

    • untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.

    Findings

    • Warn

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

      annotations: {"readOnlyHint":true,"openWorldHint":true}; The description's first verb is "convert": a word for a change.

      What this check looks for
    Description, as the server wrote it
    Convert an HTML document up to 4 MB to a PDF with Chromium (Gotenberg). Pass the HTML as base64 in `content_base64`, or as a download link in `file`. JavaScript runs, and images, fonts and CSS the HTML links by public https URL are loaded. Returns `{"download_url": "<link>", "size_bytes": <PDF size>, "expires_in_minutes": 60}`: give the user the `download_url`. Requires an API key. Credits: 1 per call.

      What this check looks for
    Description, as the server wrote it
    Convert an office document up to 4 MB to a PDF with LibreOffice (Gotenberg). Word, Excel, PowerPoint, OpenDocument and the other formats LibreOffice opens. Pass the file as base64 in `content_base64`, or as a download link in `file`, and its name in `filename`: the extension tells LibreOffice the format. Returns `{"download_url": "<link>", "size_bytes": <PDF size>, "expires_in_minutes": 60}`: give the user the `download_url`. Requires an API key. Credits: 1 per call.

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.

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

Install

Pinned to version 1.0.0. Values in angle brackets are yours to fill in.

claude mcp add --transport http gotenberg https://api.pagespool.com/mcp/gotenberg/
claude mcp add --transport http gotenberg https://api.pagespool.com/mcp/gotenberg/

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__gotenberg__html_to_pdf",
      "mcp__gotenberg__office_to_pdf"
    ],
    "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 gotenberg. Review it before you use it.

Capability tags behind 2 rules

Pin

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