## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__qr__get_dynamic_qr` `mcp__qr__list_folders` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__qr__list_dynamic_qr` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

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

### `delete_dynamic_qr`

- The name "delete_dynamic_qr" says "delete": a word for removing or ending something.
- The description says "Permanently delete".

Description, as the server wrote it:

### `delete_folder`

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

Description, as the server wrote it:

```untrusted-server-text

```untrusted-server-text
Create up to 200 dynamic QR codes at once. Requires an OpenQR API key.
```

### `clear_subdomain`

- 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
Release the branded subdomain. Codes stay live on the plain short link; only the {name}.oqr.to form stops resolving. The name becomes claimable by someone else. Requires an OpenQR API key.
```

### `create_dynamic_qr`

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

Description, as the server wrote it:

```untrusted-server-text
Create an editable (dynamic) QR code whose destination you can change later without reprinting. Requires an OpenQR API key.

```untrusted-server-text
Create a folder to organise codes. Requires an OpenQR API key.

### `create_link_alias`

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

Description, as the server wrote it:

```untrusted-server-text
Create an extra short link (link alias) that resolves where one of your dynamic codes points: share a different slug per channel while the QR keeps its own slug, so QR scans and link clicks are counted separately. Free accounts have no alias allowance; Pro includes 10. Requires an OpenQR API key.
```

### `create_static_qr`

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

Description, as the server wrote it:

```untrusted-server-text
Save a static QR code to your library from structured fields: wifi, contact (vCard), email, SMS, WhatsApp, location, text, phone or URL. Static codes bake the content into the code itself — no short link, no scan analytics, not editable later. Render the returned payload with generate_qr. Requires an OpenQR API key.
```

### `create_theme`

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

Description, as the server wrote it:

```untrusted-server-text

```

### `generate_epc_code`

- The name "generate_epc_code" says "generate": a word for a change.

Description, as the server wrote it:

```untrusted-server-text

- The name "generate_pix_code" says "generate": a word for a change.

Description, as the server wrote it:

```untrusted-server-text

```

### `generate_qr`

- The name "generate_qr" says "generate": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Generate a static QR code from any text/URL. Returns a PNG image (or SVG markup). Requires an OpenQR API key.

```

### `set_subdomain`

- The name "set_subdomain" says "set": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
