Tools

Open a tool for its reasons and full description. Descriptions are the publisher's own words, shown as they are.

  • html_to_pdfConvert HTML and CSS to a PDF document using the WeasyPrint rendering engine.Can send data outNo findings

    Why it is in this group

    • The description's first verb is "convert": a word for a change.

    What it can reach

    • outboundThe input takes a URL (input.url): a request to a URL can carry data to whoever runs it.
    Description, as the server wrote it
    Convert HTML and CSS to a PDF document using the WeasyPrint rendering engine. Supports every PDF/A archival level, PDF/UA accessibility and the PDF/X print standards. Best for professional documents: invoices, reports, certificates, contracts, and accessible documents. Also produces **fillable PDF forms** — set pdfForms to true. Send a complete HTML document including <html>, <head> with <style>, and <body> tags. Page geometry comes from the document's own CSS @page rule unless paperSize or orientation is set explicitly. Returns a temporary download URL for the generated PDF (valid for 30 minutes). Requires a paid PdfBroker.io plan (Starter or above). EU-first defaults: A4 paper, Portrait orientation when neither the document nor the caller says otherwise.

    • outboundThe input takes a URL (input.url): a request to a URL can carry data to whoever runs it.
    Description, as the server wrote it
    Convert HTML to PDF using the wkhtmltopdf rendering engine. Supports JavaScript execution and screen-capture style rendering. Good for simple documents, web page snapshots, layouts that rely on JavaScript, and **fillable PDF forms** (set pdfForms to true). Available on all PdfBroker.io plans including the free tier. Does NOT support PDF/A or PDF/UA compliance — use html_to_pdf for compliant documents. Does NOT honour CSS '@page { size: ... }' — page geometry comes from paperSize and orientation; use html_to_pdf when the document's own stylesheet must decide. EU-first defaults: A4 paper, Portrait orientation.

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.

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 out2
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

  • WarnThe whole server

    The endpoint served tools/list without credentials, and the list has 2 tools that change things (2 write). Whether a call also works without credentials was not tested: tools are never called.

    Matched text

    https://mcp.pdfbroker.io/: tools/list returned 2 tools to an anonymous client, including html_to_pdf_wk (write), html_to_pdf (write)

    What this check looks for

Install

Pinned to version 1.2.0. Values in angle brackets are yours to fill in.

claude mcp add --transport http pdf https://mcp.pdfbroker.io/ --header 'X-PdfBroker-ClientId: <your-x-pdfbroker-clientid>' --header 'X-PdfBroker-ClientSecret: <your-x-pdfbroker-clientsecret>'

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__pdf__html_to_pdf_wk",
      "mcp__pdf__html_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 pdf. Review it before you use it.
