## Exfil surface

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

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

| Private data | Untrusted input | Outbound |

| `mcp__qrforprint__preview_qr_code` | `mcp__qrforprint__preview_qr_code` | `mcp__qrforprint__preview_qr_code` |

## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (1)

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

### `update_code_destination`

- The name "update_code_destination" says "update": a word for a change.
- The input takes a statement or command to run (input.code), which can change anything it can reach.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Changes the web address a dynamic link QR code in the signed-in qrforprint account forwards to. Printed copies keep working and open the new address from the next scan. Accepts the code ID or its short link. Static codes, disabled codes and photo, PDF or voice note codes cannot be changed with this tool.
```

## Changes things (1)

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

### `create_dynamic_link_code`

- The name "create_dynamic_link_code" says "create": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Creates a dynamic QR code in the signed-in qrforprint account. The code holds a short qrforprint link that forwards to the given web address, so the destination can be changed later without reprinting, and scans are counted. Free accounts can have 3 dynamic codes. Returns the short link, the QR image and a link to style and download it on qrforprint.com.
```

## Only reads (2)

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

### `list_my_codes`

- The name "list_my_codes" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Lists the QR codes saved in the signed-in qrforprint account, newest first, 50 per page: name, type, static or dynamic, short link, destination, total scans for dynamic codes, creation date, whether the code is disabled, and a link to edit it on qrforprint.com.
```

### `preview_qr_code`

- The name "preview_qr_code" says "preview": a word for reading.
- Tag private-data: The description's first sentence says "email": it reads mail.
- Tag untrusted-input: The description's first sentence says "web": it reads web pages, which anyone can write. The input takes a URL (input.url), and the tool reads it: it reads web pages, which anyone can write.
- Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it.
- Claude Code: ask, because it is tagged outbound.

Description, as the server wrote it:

```untrusted-server-text
Draws a black and white preview of a static QR code for a web address, plain text, email, phone call, text message, WiFi network or contact card. Returns the PNG image and a link that opens the same content in the qrforprint editor, where it can be styled and downloaded as PNG, SVG, PDF or EPS. Nothing is saved and no account is needed. A static code cannot be changed after it is printed.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__qrforprint__list_my_codes"
    ],
    "ask": [
      "mcp__qrforprint__preview_qr_code",
      "mcp__qrforprint__create_dynamic_link_code"
    ],
    "deny": [
      "mcp__qrforprint__update_code_destination"
    ]
  }
}
```

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

- `mcp__qrforprint__preview_qr_code`: private-data, untrusted-input, outbound
