## Exfil surface

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

| 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. | `mcp__pdf-check__check_public_pdf` `mcp__pdf-check__quote_fix` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | `mcp__pdf-check__check_public_pdf` `mcp__pdf-check__quote_fix` |

## Findings

No check matched anything in these tool definitions.


## Changes things (2)

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

### `check_public_pdf`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- 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
Downloads one PDF from a public http or https link and reports the structure that screen readers use: whether the file is tagged, whether it has a document title and a language, how many images have no text description and on which pages, and reading-order signals (pages with columns are flagged for a person to check). Also reports the page count and which pages look scanned or contain tables. Use when the user gives a link to a PDF on a public website and asks about its accessibility or screen-reader structure. Does not open files behind a login, does not change the file, and does not say whether the file meets PDF/UA, WCAG or any law.
```

### `quote_fix`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- 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.urls): a request to a URL can carry data to whoever runs it.

Description, as the server wrote it:

```untrusted-server-text
For one to five links to PDFs on public websites, counts pages by type and returns a price estimate from CyberNative AI LLC's published Terms for two options: an accessible web page made from the PDF (USD 6 per page with tables or scanned pages, USD 4 per other page), and, where the file qualifies, the same PDF with tags added (USD 4 per page, minimum USD 100 per order). Lists files and pages that are not converted, such as fillable forms, maps and drawings, with the reason. The estimate is not binding and nothing is ordered by calling this tool; the price is confirmed by email before any work. Use when the user asks what it would cost to have these PDFs made accessible.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `pdf-check`:

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__pdf-check__check_public_pdf",
      "mcp__pdf-check__quote_fix"
    ],
    "deny": []
  }
}
```

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

- `mcp__pdf-check__check_public_pdf`: untrusted-input, outbound
- `mcp__pdf-check__quote_fix`: untrusted-input, outbound
