## 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__backgone__remove_background` |
| 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" not destructive (destructiveHint: false), and its own name, description or input give the class "destructive".

annotations: {"readOnlyHint":false,"destructiveHint":false,"idempotentHint":false,"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 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

Description, as the server wrote it:

```untrusted-server-text
Removes the background from one image with BackGone’s production engine and returns a transparent PNG (or WebP) inline. Costs 1 API credit on success; failed calls are not charged. Requires an API key sent as "Authorization: Bearer sk_..." — create one at https://backgone.com/settings/apikeys and top up API credits at https://backgone.com/pricing. Provide exactly one of image_url or image_base64.
```

## Changes things (1)

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

### `check_photo_requirements`

- 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
Free. Returns the official passport or ID photo requirements for a country (printed size, head height, background, digital file rules, whether editing is allowed, the official source URL and the date we verified it). Call without a country to list the countries covered. No API key needed.
```

## Only reads (1)

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

### `get_pricing`

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

Description, as the server wrote it:

```untrusted-server-text
Free. Returns the current BackGone prices: API credit top-up packs (one image = one API credit, credits never expire) and the website subscription/credit-pack tiers. No API key needed.
```

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__backgone__get_pricing"
    ],
    "ask": [
      "mcp__backgone__check_photo_requirements"
    ],
    "deny": [
      "mcp__backgone__remove_background"
    ]
  }
}
```

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

- `mcp__backgone__remove_background`: untrusted-input
