Title and description, as the publisher wrote them:

```untrusted-server-text
Privacy-first PDF tools over MCP: merge, split, rotate, delete, compress, protect, inspect.
```

Scanned 2026-10-21T19:03:59.460Z over streamable-http.

**7 tools: 1 can delete or cancel things, 2 do something that can't be undone, 3 change things and 1 only read.**

| Group | Class | Tools | Claude Code |
| --- | --- | --- | --- |
| Deletes or cancels | destructive | 1 | deny |
| Can't be undone | irreversible | 2 | ask |
| Changes things | write | 3 | ask |
| Only reads | read | 1 | allow |

## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__fixmypdf__split_pdf` |

## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (1)

Removes, cancels or revokes something. Claude Code: deny.

### `delete_pages`

- The name "delete_pages" says "delete": a word for removing or ending something.

Description, as the server wrote it:

```untrusted-server-text
Remove specific pages from a PDF by their 1-based page numbers, keeping the rest in order. Returns base64.
```

## Can't be undone (2)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `merge_pdf`

- The name "merge_pdf" says "merge": a word for a change that another call does not undo.

Description, as the server wrote it:

```untrusted-server-text
Merge two or more PDFs into one, in the order given. Returns the merged PDF as base64.
```

### `split_pdf`

- The input addresses people (input.to): what it sends cannot be taken back.
- Tag outbound: The input takes a destination (input.to): what the tool writes goes there.

Description, as the server wrote it:

```untrusted-server-text
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 (3)

Creates or changes something that can be changed back. Claude Code: ask.

### `compress_pdf`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
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_pdf`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Encrypt a PDF with a password (AES). The result requires the password to open. Returns base64.
```

### `rotate_pdf`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
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 (1)

Looks things up and changes nothing. Claude Code: allow.

### `get_pdf_info`

- The name "get_pdf_info" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Read-only. Return a PDF's page count and per-page dimensions (in points). Use this first to plan a split or rotate.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `fixmypdf`:

```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"
    ]
  }
}
```

Capability tags behind the rules (a read tagged outbound is asked about):

- `mcp__fixmypdf__split_pdf`: outbound

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:53:26.260Z, unchanged since 2026-10-22T14:53:26.260Z. No credentials were sent and no tool was called. Values are shown as the endpoint returned them. Method: https://anlyon.dev/methodology#remote-posture

| Fact | Observed |
| --- | --- |
| Reachable | `yes` |
| HTTP status of an anonymous initialize | `200` |
| tools/list served without credentials | `yes` |
| Tools that change things, listed without credentials | `6` |
| 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` |

- **high** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
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.

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
