## Why domains.dns_records is rated Low

This tool retrieves DNS record information from a domain's DNS configuration. It has no side effects, does not modify data, execute code, or delete anything. It is a straightforward data query operation comparable to nslookup or dig commands used for DNS lookups.

From the tool's own definition: "Tool description states it 'Fetch[es] DNS records for a domain' and 'Returns an array of records.' The action is purely retrieval with no modification, deletion, or execution capability."

## Use case

AI agents call domains.dns_records to retrieve information from Vee3 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 Vee3:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "domains.dns_records": {}
  }
}
```
