## Why localant_doctor is rated Low

This tool retrieves and reports system and configuration information about the LocalAnt gateway itself without modifying any state, executing commands, or triggering external operations. It is purely informational diagnostics with read-only access patterns. The explicit 'read-only' designation and 'Risk 0' assertion in the description confirm low severity.

From the tool's own definition: "Tool name includes 'doctor' (diagnostics), description explicitly states 'Read-only diagnostics' and lists inspection operations: connection/version checks, counting exposed tools, listing allowed directories, checking state (tunnel/Tailscale), querying OS…"

## Use case

AI agents call localant_doctor to retrieve information from LocalAnt without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches LocalAnt:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "localant_doctor": {}
  }
}
```
