## Why validate_ptr_records is rated Low

This tool performs validation and inspection of PTR records, which is a read-only operation that queries DNS configuration state. It has no side effects—it does not create, modify, delete, execute code, or commit financial actions. The blast radius of misuse is minimal since validation operations cannot harm system state or data.

From the tool's own definition: "Tool name 'validate_ptr_records' and description 'Validate current PTR (reverse DNS) records' indicate a query/check operation that retrieves and validates existing DNS configuration without modifying or deleting data."

## Use case

AI agents call validate_ptr_records to retrieve information from cPanel MCP Server 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 cPanel MCP Server:

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