## 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__app-data__browse_category` `mcp__app-data__find_alternatives` `mcp__app-data__get_app` `mcp__app-data__get_app_privacy` `mcp__app-data__get_app_reviews` `mcp__app-data__get_developer_apps` `mcp__app-data__search_apps` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__app-data__search_apps",
      "mcp__app-data__get_app",
      "mcp__app-data__find_alternatives",
      "mcp__app-data__browse_category",
      "mcp__app-data__get_app_reviews",
      "mcp__app-data__get_app_privacy",
      "mcp__app-data__get_developer_apps"
    ],
    "ask": [],
    "deny": []
  }
}
```

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

- `mcp__app-data__search_apps`: untrusted-input
- `mcp__app-data__get_app`: untrusted-input
- `mcp__app-data__find_alternatives`: untrusted-input
- `mcp__app-data__browse_category`: untrusted-input
