## 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__image-tools__check_image_service` `mcp__image-tools__remove_background` `mcp__image-tools__restore_face` `mcp__image-tools__upscale_image` |
| 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 `remove_background` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

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

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":true}; The name "remove_background" says "remove": a word for removing or ending something.
```

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

```untrusted-server-text
The server marks "remove_background" not destructive (destructiveHint: false), and its own name, description or input give the class "destructive".

annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":true}; The name "remove_background" says "remove": a word for removing or ending something.
```


## Deletes or cancels (1)

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

### `remove_background`

- The name "remove_background" says "remove": a word for removing or ending something.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- The server marks it not destructive (destructiveHint: false), 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.
- Findings: warn annotation-conflict, warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Remove the background from an image.

Uses BiRefNet segmentation to precisely separate foreground from background.
Returns a base64-encoded image with transparent background (PNG) or white
background (WebP). Sub-500ms latency on GPU.

Args:
    image_base64: Base64-encoded image data (PNG, JPEG, or WebP).
    output_format: Output format -- 'png' (with transparency) or 'webp'.

Returns:
    dict with keys:
        - image_base64 (str): Base64-encoded result image
        - format (str): Output image format
        - original_size (dict): Original width and height
        - processing_ms (int): Processing time in milliseconds
```

## Changes things (3)

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

### `check_image_service`

- 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 health status of Image API services and loaded models.

Returns:
    dict with keys:
        - status (str): 'healthy' or error state
        - models (dict): Loaded model status per capability
        - version (str): API version
```

### `restore_face`

- 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
Restore and enhance faces in an image using GFPGAN.

Detects all faces via RetinaFace, restores quality (fixes blur, noise,
compression artifacts), and pastes them back. Optionally enhances the
background using Real-ESRGAN. GPU-accelerated, sub-3s latency.

Args:
    image_base64: Base64-encoded image data containing faces (PNG, JPEG, WebP).
    upscale: Output upscale factor -- 1 to 4 (default: 2).
    enhance_background: Whether to enhance background with Real-ESRGAN (default: true).

Returns:
    dict with keys:
        - image (str): Base64-encoded restored image
        - format (str): Output image format
        - width (int): Output width
        - height (int): Output height
        - upscale (int): Scale factor applied
        - processing_time_ms (float): Processing time in milliseconds
```

### `upscale_image`

- 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
Upscale image resolution using Real-ESRGAN.

Enhances image resolution by 2x or 4x using GPU-accelerated Real-ESRGAN
super-resolution. Processes in tiles (256x256) to manage VRAM.
Maximum output dimension: 8192x8192.

Args:
    image_base64: Base64-encoded image data (PNG, JPEG, or WebP).
    scale: Upscale factor -- 2 or 4 (default: 4).

Returns:
    dict with keys:
        - image (str): Base64-encoded upscaled image
        - format (str): Output image format
        - width (int): Output width
        - height (int): Output height
        - scale (int): Scale factor applied
        - processing_time_ms (float): Processing time in milliseconds
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `image-tools`:

```json
{
  "permissions": {
    "allow": [],
    "ask": [
      "mcp__image-tools__upscale_image",
      "mcp__image-tools__restore_face",
      "mcp__image-tools__check_image_service"
    ],
    "deny": [
      "mcp__image-tools__remove_background"
    ]
  }
}
```

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

- `mcp__image-tools__remove_background`: untrusted-input
- `mcp__image-tools__upscale_image`: untrusted-input
- `mcp__image-tools__restore_face`: untrusted-input
- `mcp__image-tools__check_image_service`: untrusted-input
