## 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__whiteboard-animation__wait_render` |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__whiteboard-animation__wait_render` |
| 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 `status` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"openWorldHint":false}; The name "status" says "status": a word for reading.
```

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

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

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


## Changes things (5)

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

### `create_drawing`

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

Description, as the server wrote it:

```untrusted-server-text
Draw a picture as a whiteboard animation. Spends credits (see quote). Answers at once with the drawing_id; the drawing takes a few minutes, follow it with get_drawing.
```

### `create_upload`

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

Description, as the server wrote it:

```untrusted-server-text
Start uploading a picture: answers an upload_url to PUT the bytes to, with the given headers. Then call create_drawing with the upload_id. Not needed when the host attaches the picture to create_drawing itself.
```

### `quote`

- 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.

Description, as the server wrote it:

```untrusted-server-text
What drawing one picture costs, in credits, and the quote_version to pass when creating it.
```

### `render_link`

- The name "render_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
One link that renders up to 20 of your drawings as files, each with its own choices (format, resolution, aspect, background, hand…; see get_drawing export_options). Opening it in a browser renders them one after another and saves each file to that browser’s downloads; drawings still being drawn are rendered once they finish. Follow it with wait_render.
```

### `status`

- The name "status" says "status": a word for reading.
- The description's first verb is "call": 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
Call first. The signed-in workspace: its plan, credits left, drawings queued and running, and how many may queue.
```

## Only reads (4)

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

### `get_drawing`

- The name "get_drawing" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
A drawing by id: its status and progress, its preview page, and once done the export options render_link accepts for it.
```

### `list_drawings`

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

Description, as the server wrote it:

```untrusted-server-text
The latest drawings in the library, newest first.
```

### `wait_drawing`

- The name "wait_drawing" says "wait": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
For the drawing card: answers get_drawing as soon as the drawing moves on from the status and progress the card last showed, or after about 50 seconds.
```

### `wait_render`

- The name "wait_render" says "wait": a word for reading.
- Tag private-data: The description's first sentence says "file": it reads files.
- Tag untrusted-input: The description's first sentence says "browser": it reads web pages, which anyone can write.

Description, as the server wrote it:

```untrusted-server-text
A render link’s files: each drawing’s state (pending, rendering, saved, failed) and, once saved, its file name and size in the browser’s downloads. Pass back the states of the last answer: it answers as soon as any of them moves on, or after about 50 seconds.
```

## Claude Code permissions
