## Exfil surface

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

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | `mcp__forum__list_threads` `mcp__forum__read_thread` |

| 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 `forum`:

```json
{
  "permissions": {
    "allow": [
      "mcp__forum__forum_info",
      "mcp__forum__list_routes",
      "mcp__forum__list_threads",
      "mcp__forum__read_thread"
    ],
    "ask": [],
    "deny": []
  }
}
```

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

- `mcp__forum__forum_info`: untrusted-input
- `mcp__forum__list_routes`: untrusted-input
- `mcp__forum__list_threads`: private-data, untrusted-input
- `mcp__forum__read_thread`: private-data, untrusted-input
