## Exfil surface

2 private-data -> untrusted-input -> outbound paths in this server alone. Denying 1 outbound tool breaks every one: `mcp__pdf-splitter__pdf_upload`.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__pdf-splitter__pdf_count` `mcp__pdf-splitter__pdf_files` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__pdf-splitter__license_status` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__pdf-splitter__pdf_upload` |

| Private data | Untrusted input | Outbound |
| --- | --- | --- |
| `mcp__pdf-splitter__pdf_count` | `mcp__pdf-splitter__license_status` | `mcp__pdf-splitter__pdf_upload` |
| `mcp__pdf-splitter__pdf_files` | `mcp__pdf-splitter__license_status` | `mcp__pdf-splitter__pdf_upload` |

## Findings

- **warn** Annotations that disagree with the tool in `pdf_count` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "pdf_count" as not read-only (readOnlyHint: false), and its words say it reads.

annotations: {"readOnlyHint":false,"destructiveHint":false,"idempotentHint":false,"openWorldHint":false}; The name "pdf_count" says "count": a word for reading.
```

- **warn** Annotations that disagree with the tool in `pdf_text` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "pdf_text" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The description's first verb is "call": a word for a change.
```


## Deletes or cancels (1)

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

### `pdf_delete_upload`

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

Description, as the server wrote it:

```untrusted-server-text
Delete one PDF stored for your token, uploaded or generated.
```

## Can't be undone (2)

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

### `pdf_merge`

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

Description, as the server wrote it:

```untrusted-server-text
Call this tool to join several PDFs into one, in the order given. Page sizes are kept as-is, so a merged file may have mixed sizes, and the answer says so. Inputs are never modified. Free tier: up to 5 files per merge.
```

### `pdf_upload`

- The name "pdf_upload" says "upload": a word for a change.
- The description's first verb is "send": a word for sending, and what is sent cannot be taken back.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
Send a PDF to this hosted endpoint. There is no filesystem here, so instead of a path you upload the file once with pdf_upload and then pass its name as `path` (or inside `paths`) to pdf_info, pdf_count, pdf_merge, pdf_split, pdf_pages, pdf_rotate, pdf_stamp, pdf_reorder and pdf_text. Give exactly one of pdf_base64 or url. url: fetch a public file instead of pasting base64 (recommended above about 10 KB): pasting a large base64 payload is slow to write out and can stall the turn before the call is ever sent, while a url costs one line and the fetch happens here. Uploads are kept for your token between calls; pdf_files lists them and pdf_delete_upload removes one. A file this server writes is named the same way and comes back as a download link valid for one hour. The request body cap is 256 KB, which is about 190 KB of PDF once base64-encoded; a url is fetched with a 10 second timeout, at most 3 redirects, public http(s) hosts only, and is capped at 2 MB.
```

## Changes things (10)

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

### `license_activate`

- 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
Turn Pro on for this connection with key, an MCPL1.<payload>.<signature> issued at checkout for this server or the bundle. Data under your token stays; a wrong or expired key changes nothing. license_status confirms it.
```

### `pdf_count`

- The name "pdf_count" says "count": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Tag private-data: The description's first sentence says "file": it reads files.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Page count per file plus the total, for any number of PDFs, with how many were readable. A file that cannot be read is reported on its own row and the others still count. Read-only. Free and unlimited.
```

### `pdf_info`

- The description's first verb is "call": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Call this tool to inspect a PDF: page count, page sizes in points/mm, paper name, metadata (title, author, producer, dates) and whether it is encrypted. Read-only, never modifies the file. Free tier: unlimited.
```

### `pdf_pages`

- The description's first verb is "call": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Call this tool to pull selected pages into one new PDF, in the order written: "2,4-6" gives four pages. Asking for a page twice copies it twice. The input is never modified. Free tier: files up to 30 pages.
```

### `pdf_reorder`

- The description's first verb is "call": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Call this tool to write a new PDF with pages in the order you give. The order must name every page exactly once, so nothing drops by accident; use pdf_pages for a subset. Pro.
```

### `pdf_rotate`

- The description's first verb is "call": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Call this tool to turn pages by a multiple of 90 degrees, clockwise for positive. Rotation is added to whatever the page already had, for a sideways scan. Writes a new file. Free tier: files up to 30 pages.
```

### `pdf_split`

- The description's first verb is "call": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Call this tool to write one new PDF per range. Ranges are 1-based and may be open-ended: "1-3,5,7-" gives pages 1-3, page 5, and 7 to the end. The input is never modified. Free tier: files up to 30 pages.
```

### `pdf_stamp`

- The description's first verb is "call": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Call this tool to draw a word such as PAID or DRAFT across the pages, in a colour and position you choose. Writes a new file; input untouched. Free tier: the PAID and DRAFT presets in their preset colours.
```

### `pdf_text`

- The description's first verb is "call": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Call this tool for best-effort text extraction from standard-font PDFs. Returns nothing for a scan (no OCR), or glyph indices for a custom-encoded font, and says which case applies. Read-only. Free tier: unlimited.
```

### `pdf_watermark_business`

- The description's first verb is "call": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Call this tool to put your business name and VAT id in the footer of every page, from the shared profile mcp-invoice and mcp-docx write. Use it before sending a document out. Pro.
```

## Only reads (2)

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

### `license_status`

- The name "license_status" says "status": a word for reading.
- Tag untrusted-input: The description's first sentence says "url": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
Report this endpoint's licence state for your token as JSON: the product, the tier free or pro, why it is not Pro, and the checkout URL. Call it to explain a free-tier refusal. No arguments, nothing changes.
```

### `pdf_files`

- The description's first verb is "list": a word for reading.
- Tag private-data: The name "pdf_files" says "file": it reads files.

Description, as the server wrote it:

```untrusted-server-text
List the PDFs stored for your token: what you uploaded, and what this server has written, with their sizes.
```

- `mcp__pdf-splitter__pdf_upload`: outbound
- `mcp__pdf-splitter__pdf_files`: private-data

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T15:28:21.183Z, unchanged since 2026-10-22T15:28:21.183Z. 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 |

- **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 13 tools that change things (1 destructive, 2 irreversible, 10 write). Whether a call also works without credentials was not tested: tools are never called.

https://mcp.zovo.one/mcp/pdf-splitter: tools/list returned 15 tools to an anonymous client, including pdf_delete_upload (destructive), pdf_merge (irreversible), pdf_upload (irreversible), pdf_info (write), pdf_count (write) and 8 more
