## Exfil surface

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

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

| Private data | Untrusted input | Outbound |
| --- | --- | --- |
| `mcp__filetopdf__get_account` | `mcp__filetopdf__convert_file` | `mcp__filetopdf__convert_file` |
| `mcp__filetopdf__get_account` | `mcp__filetopdf__convert_html` | `mcp__filetopdf__convert_file` |
| `mcp__filetopdf__get_account` | `mcp__filetopdf__convert_markdown` | `mcp__filetopdf__convert_file` |
| `mcp__filetopdf__get_account` | `mcp__filetopdf__get_account` | `mcp__filetopdf__convert_file` |

## Findings

No check matched anything in these tool definitions.


## Changes things (3)

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

### `convert_file`

- The name "convert_file" says "convert": a word for a change.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.
- 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
Convert a file fetched from a public URL into a PDF. Auto-detects the engine from the extension: Office docs (DOCX, XLSX, PPTX, ODT, RTF, TXT, CSV…), images (PNG, JPG, WebP…), HTML, Markdown, or an existing PDF (passthrough). Costs 1 credit on success. Returns the PDF as an embedded resource.
```

### `convert_html`

- The name "convert_html" says "convert": a word for a change.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Render a raw HTML string to a PDF using Chromium, with optional CSS and layout options. Costs 1 credit on success. Returns the PDF as an embedded resource.
```

### `convert_markdown`

- The name "convert_markdown" says "convert": a word for a change.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Render a raw Markdown string to a PDF, with optional CSS and layout options. A sensible default stylesheet is applied when no CSS is given. Costs 1 credit on success. Returns the PDF as an embedded resource.
```

## Only reads (1)

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

### `get_account`

- The name "get_account" says "get": a word for reading.
- Tag private-data: The description's first sentence says "file": it reads files.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Check the FileToPDF API key and return the plan, remaining conversion credits, and subscription status. Free — costs no credits. Use this to verify the connection works.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__filetopdf__get_account"
    ],
    "ask": [
      "mcp__filetopdf__convert_file",
      "mcp__filetopdf__convert_html",
      "mcp__filetopdf__convert_markdown"
    ],
    "deny": []
  }
}
```

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

- `mcp__filetopdf__get_account`: private-data, untrusted-input
- `mcp__filetopdf__convert_file`: untrusted-input, outbound
- `mcp__filetopdf__convert_html`: untrusted-input
- `mcp__filetopdf__convert_markdown`: untrusted-input

## Remote posture

What an anonymous client saw at the remote endpoint, last 2026-10-22T14:45:54.875Z, unchanged since 2026-10-22T14:45:54.875Z. 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 | `3` |
| 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` |

- **warn** 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 3 tools that change things (3 write). Whether a call also works without credentials was not tested: tools are never called.

https://api.filetopdf.dev/mcp: tools/list returned 4 tools to an anonymous client, including convert_file (write), convert_html (write), convert_markdown (write)
