Findings

    Why it is in this group

    • The name "convert_file" says "convert": a word for a change.
    • The input addresses people (input.to): what it sends 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.
    • outboundThe input takes a destination (input.to): what the tool writes goes there.
    • outboundThe input takes a URL (input.url): a request to a URL can carry data to whoever runs it.

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 write10
Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
Can send data out8
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.

  • HighThe whole server

    The endpoint served tools/list without credentials, and the list has 5 tools that change things (1 irreversible, 4 write). Whether a call also works without credentials was not tested: tools are never called.

    Matched text

    https://agent-tools-production-e6aa.up.railway.app/mcp: tools/list returned 10 tools to an anonymous client, including convert_file (irreversible), pdf_tables_to_json (write), html_to_pdf (write), transcribe_audio (write), uk_company_check (write)

    What this check looks for

Install

Pinned to version 1.1.0. Values in angle brackets are yours to fill in.

claude mcp add --transport http agent-tools-uk https://agent-tools-production-e6aa.up.railway.app/mcp

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__agent-tools-uk__uk_postcode_lookup"
    ],
    "ask": [
      "mcp__agent-tools-uk__screenshot_webpage",
      "mcp__agent-tools-uk__webpage_to_markdown",
      "mcp__agent-tools-uk__pdf_tables_to_json",

      "mcp__agent-tools-uk__website_status_check"
    ],
    "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 agent-tools-uk. Review it before you use it.
