Tools

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

7 tools

Deletes or cancels 1Claude Code: deny
  • delete_pagesRemove specific pages from a PDF by their 1-based page numbers, keeping the rest in order.No findings

    Why it is in this group

    • The name "delete_pages" says "delete": a word for removing or ending something.
    Description, as the server wrote it
    Remove specific pages from a PDF by their 1-based page numbers, keeping the rest in order. Returns base64.
Can't be undone 2Claude Code: ask
  • merge_pdfMerge two or more PDFs into one, in the order given.No findings

    Why it is in this group

    • The name "merge_pdf" says "merge": a word for a change that another call does not undo.
    Description, as the server wrote it
    Merge two or more PDFs into one, in the order given. Returns the merged PDF as base64.
  • split_pdfExtract an inclusive, 1-based page range from a PDF into a new PDF.Can send data outNo findings

    Why it is in this group

    • The input addresses people (input.to): what it sends cannot be taken back.

    What it can reach

    • outboundThe input takes a destination (input.to): what the tool writes goes there.
    Description, as the server wrote it
    Extract an inclusive, 1-based page range from a PDF into a new PDF. e.g. from=5,to=10 keeps pages 5–10. Returns base64.
Changes things 3Claude Code: ask
  • compress_pdfReduce a PDF's file size losslessly by consolidating object streams (keeps text selectable).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.
    Description, as the server wrote it
    Reduce a PDF's file size losslessly by consolidating object streams (keeps text selectable). Returns base64 plus before/after sizes. Note: does not re-encode embedded images.
  • protect_pdfEncrypt a PDF with a password (AES).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.
    Description, as the server wrote it
    Encrypt a PDF with a password (AES). The result requires the password to open. Returns base64.
  • rotate_pdfRotate pages of a PDF clockwise by 90, 180, or 270 degrees.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.
    Description, as the server wrote it
    Rotate pages of a PDF clockwise by 90, 180, or 270 degrees. Omit "pages" to rotate every page; otherwise pass 1-based page numbers. Returns base64.
Only reads 1Claude Code: allow
  • get_pdf_infoRead-only.No findings

    Why it is in this group

    • The name "get_pdf_info" says "get": a word for reading.
    Description, as the server wrote it
    Read-only. Return a PDF's page count and per-page dimensions (in points). Use this first to plan a split or rotate.

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 out1
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 6 tools that change things (1 destructive, 2 irreversible, 3 write). Whether a call also works without credentials was not tested: tools are never called.

    Matched text

    https://www.fixmypdfonline.com/api/mcp: tools/list returned 7 tools to an anonymous client, including delete_pages (destructive), merge_pdf (irreversible), split_pdf (irreversible), rotate_pdf (write), compress_pdf (write) and 1 more

    What this check looks for

Install

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

claude mcp add --transport http fixmypdf https://www.fixmypdfonline.com/api/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__fixmypdf__get_pdf_info"
    ],
    "ask": [
      "mcp__fixmypdf__merge_pdf",
      "mcp__fixmypdf__split_pdf",
      "mcp__fixmypdf__rotate_pdf",
      "mcp__fixmypdf__compress_pdf",
      "mcp__fixmypdf__protect_pdf"
    ],
    "deny": [
      "mcp__fixmypdf__delete_pages"
    ]
  }
}

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 fixmypdf. Review it before you use it.
