**2 tools: 1 change things and 1 only read.**

| Group | Class | Tools | Claude Code |
| --- | --- | --- | --- |
| Deletes or cancels | destructive | 0 | deny |
| Can't be undone | irreversible | 0 | ask |
| Changes things | write | 1 | ask |
| Only reads | read | 1 | allow |

## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input 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. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

- **warn** Annotations that disagree with the tool in `studio_link` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "studio_link" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "studio_link" says "link": a word for a change.
```


## Changes things (1)

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

### `studio_link`

- The name "studio_link" says "link": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Returns a link to the Cuecaps studio set up with these caption settings, and the steps to give the user: they open it, add their video, click Find words and export an MP4 with captions burned in, a transparent overlay or an SRT or VTT file. The video stays on their device. Works on every plan, Free included.
```

## Only reads (1)

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

### `list_styles`

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

Description, as the server wrote it:

```untrusted-server-text
Lists the 10 Cuecaps caption styles: the id to pass as style to studio_link, the name, and how each one looks. Call it when the user hasn't picked a style or asks what the styles look like.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__cuecaps__list_styles"
    ],
    "ask": [
      "mcp__cuecaps__studio_link"
    ],
    "deny": []
  }
}
```

- **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 1 tool that changes things (1 write). Whether a call also works without credentials was not tested: tools are never called.

https://cuecaps.com/mcp: tools/list returned 2 tools to an anonymous client, including studio_link (write)
