## 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

No check matched anything in these tool definitions.


## Changes things (1)

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

### `scale_objects_from_credit_card`

- 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
Scale object pixel dimensions using a standard CR80 credit card reference.

    Args:
        image_id: Caller-defined source identifier; no image is uploaded.
        credit_card_pixel_width: Caller-supplied pixel width of a CR80-size card.
        objects: Objects to scale. Each object needs pixel_width and pixel_height;
            label, pixel_area, pixel_perimeter, and input confidence are optional.
        credit_card_pixel_height: Optional caller-supplied height for distortion check.
        payment_ref: Optional paid escrow reference consumed by the gateway.
        request_id: Optional retry-safe idempotency key (maximum 128 characters).
    
```

## Only reads (3)

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

### `credit_card_photo_instructions`

- The description's first verb is "return": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Return safe capture guidance for upstream CR80 pixel picking.

    The image stays with the caller or upstream vision system; SmartScale only
    receives numeric pixel geometry.
    
```

### `describe`

- The name "describe" says "describe": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Return SmartScale capabilities and input contract.
```

### `health`

- The description's first verb is "return": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Return SmartScale health status.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__smartscale__credit_card_photo_instructions",
      "mcp__smartscale__describe",
      "mcp__smartscale__health"
    ],
    "ask": [
      "mcp__smartscale__scale_objects_from_credit_card"
    ],
    "deny": []
  }
}
```
