## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged untrusted-input or outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__bmlt-server__get_meeting` `mcp__bmlt-server__list_formats` `mcp__bmlt-server__search_meetings` |
| 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 |

## Claude Code permissions

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

```json
{
  "permissions": {
    "allow": [
      "mcp__bmlt-server__search_meetings",
      "mcp__bmlt-server__get_meeting",
      "mcp__bmlt-server__list_formats",
      "mcp__bmlt-server__list_service_bodies",
      "mcp__bmlt-server__get_server_info",
      "mcp__bmlt-server__list_root_servers"
    ],
    "ask": [],
    "deny": []
  }
}
```

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

- `mcp__bmlt-server__search_meetings`: private-data
- `mcp__bmlt-server__get_meeting`: private-data
- `mcp__bmlt-server__list_formats`: private-data
