## Why kerberos_config is rated Low

This tool retrieves Kerberos configuration settings without altering any state or data. It performs a read-only query operation. While Kerberos configuration may contain sensitive information, the tool itself only exposes data retrieval capabilities with no side effects, placing it firmly in the Read category with low severity.

From the tool's own definition: "Tool name 'kerberos_config' with description 'Get Kerberos configuration settings' uses the verb 'Get', which indicates data retrieval without modification."

## Use case

AI agents call kerberos_config to retrieve information from Truenas 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 Truenas:

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