## 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__html-now__convert_image_url` `mcp__html-now__get_api_usage` `mcp__html-now__get_conversion_status` `mcp__html-now__list_converters` |
| 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 `html-now`:

```json
{
  "permissions": {
    "allow": [
      "mcp__html-now__list_converters",
      "mcp__html-now__get_conversion_status",
      "mcp__html-now__get_api_usage"
    ],
    "ask": [
      "mcp__html-now__convert_image_url"
    ],
    "deny": []
  }
}
```

- `mcp__html-now__convert_image_url`: untrusted-input
- `mcp__html-now__get_conversion_status`: untrusted-input
