url_to_screenshotCapture a page as an image.Reads text others writeCan send data out1 finding
Why it is in this group
- The name "url_to_screenshot" says "screenshot": a word for reading.
- The description's first verb is "capture": a word that usually means money moves, which cannot be taken back.
- 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.
- untrusted-inputThe name "url_to_screenshot" says "screenshot" and "url": it reads web pages, which anyone can write.
- untrusted-inputThe input takes a URL (input.url), and the tool reads it: it reads web pages, which anyone can write.
- 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
Capture a page as an image. Requires an API key purchased at https://url-pdf.hammbox.com/buy. If this MCP request carries a valid "x-api-key" or "Authorization: Bearer" header, it renders directly and returns a 1-hour download URL; otherwise it returns purchase guidance.

url_to_extractExtract structured data from a page as JSON: title, meta description, canonical URL, language, main text and links.Reads text others writeCan send data outNo 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.

Extract structured data from a page as JSON: title, meta description, canonical URL, language, main text and links. Readability-first, no LLM involved. Requires an API key purchased at https://url-pdf.hammbox.com/buy. Same auth as the other paid tools.

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.

Reads private data0: Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write5: Brings in text someone else can write: web pages, inbound email, messages, issues and comments.; list_capabilities
url_to_extract
url_to_markdown
url_to_pdf
url_to_screenshot
Can send data out4: Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.; url_to_extract
url_to_markdown
url_to_pdf
url_to_screenshot

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.

Looked at Oct 22, 2026, 15:06 UTC, unchanged since Oct 22, 2026. No credentials were sent and no tool was called. What is looked at.

Reachable: yes
HTTP status of an anonymous initialize: 200
tools/list served without credentials: yes
Tools that change things, listed without credentials: 4
Protocol version: 2025-06-18
WWW-Authenticate on 401: not observed
resource_metadata in WWW-Authenticate: none
RFC 9728 protected resource metadata: none
Authorization servers: none
Legacy HTTP+SSE transport: no
Dynamic client registration: not observed
Client ID metadata documents: not observed

HighThe whole server
The endpoint served tools/list without credentials, and the list has 4 tools that change things (1 irreversible, 3 write). Whether a call also works without credentials was not tested: tools are never called.
Matched text
https://url-pdf.hammbox.com/mcp: tools/list returned 5 tools to an anonymous client, including url_to_screenshot (irreversible), url_to_pdf (write), url_to_markdown (write), url_to_extract (write)
What this check looks for

Install

Pinned to version 0.2.1. Values in angle brackets are yours to fill in.

claude mcp add --transport http url-to-pdf https://url-pdf.hammbox.com/mcp --header 'x-api-key: <your-x-api-key>'

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__url-to-pdf__list_capabilities"
    ],
    "ask": [
      "mcp__url-to-pdf__url_to_pdf",
      "mcp__url-to-pdf__url_to_screenshot",
      "mcp__url-to-pdf__url_to_markdown",
      "mcp__url-to-pdf__url_to_extract"
    ],
    "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 url-to-pdf. Review it before you use it.

Keep track

Get told when this server's tools change: a new tool, a new description, a new class.

An Atom feed. Works in any feed reader or Slack's RSS app.

Anlyon alternative

4 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.
