## Exfil surface

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

| 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__verapdf__check_pdf_accessibility` `mcp__verapdf__validate_pdfa` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

No check matched anything in these tool definitions.


## Changes things (1)

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

### `check_pdf_accessibility`

- 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.

Description, as the server wrote it:

```untrusted-server-text
Check whether a PDF is accessible by PDF/UA, the ISO standard for accessible PDF.

veraPDF checks the machine-checkable rules of PDF/UA: tags, structure, alt
text present, fonts, metadata. Whether alt text or reading order make sense
still needs a person.

Input: `pdf_base64` is the PDF as base64, at most 4 MB decoded; or pass the
file as a download link in `file`. `profile` is "ua1" or "ua2".

Returns `compliant` (true or false), `profile_name`, `statement`,
`passed_rules`, `failed_rules` and `top_failed_rules`: up to 10 failed rules
with their `id` (clause and test number), `specification`, `description` and
`failed_checks`. A file that is not a PDF fails with `not_a_pdf`; an
unavailable veraPDF with `engine_unavailable`. For the full report, use the
REST API (`POST /v1/verapdf/api/validate/ua1`).

Credits: 10 per call.
```

## Only reads (1)

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

### `validate_pdfa`

- The name "validate_pdfa" says "validate": a word for reading.
- 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 whether a PDF conforms to PDF/A, the ISO archiving standard, with veraPDF.

Input: `pdf_base64` is the PDF as base64, at most 4 MB decoded; or pass the
file as a download link in `file`. `profile` picks the PDF/A part and level.

Returns `compliant` (true or false), `profile_name` (the profile veraPDF
used), `statement`, `passed_rules`, `failed_rules` and `top_failed_rules`:
up to 10 failed rules with their `id` (clause and test number),
`specification`, `description` and `failed_checks`. A file that is not a PDF
fails with `not_a_pdf`; an unavailable veraPDF with `engine_unavailable`.
For the full report in JSON, XML or HTML, use the REST API
(`POST /v1/verapdf/api/validate/{profile}`).

Credits: 2 per call.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__verapdf__validate_pdfa"
    ],
    "ask": [
      "mcp__verapdf__check_pdf_accessibility"
    ],
    "deny": []
  }
}
```

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

- `mcp__verapdf__validate_pdfa`: untrusted-input
- `mcp__verapdf__check_pdf_accessibility`: untrusted-input
