WHAT IT DOES

What dnsenum_scan does on Kali Linux Security Tools MCP Server

AI agents invoke dnsenum_scan to trigger actions in Kali Linux Security Tools MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why dnsenum_scan needs a policy

dnsenum actively probes DNS servers, performs zone transfers, and brute-forces subdomains against target domains. This constitutes execution of an external network operation whose effects depend on arguments (target domain). The explicit warning indicates potential for misuse.

From the tool's definition 'Enumerate DNS information using dnsenum' and 'WARNING: Only scan authorized domains' — runs active DNS enumeration against external targets
