WHAT IT DOES

What dnsenum_scan does on Bug Bounty MCP Server

WHY IT NEEDS A POLICY

Why dnsenum_scan needs a policy

dnsenum is a well-known DNS enumeration tool that actively queries DNS servers, performs zone transfers, and conducts brute-force subdomain discovery against target domains. Running such a tool constitutes executing an external operation with effects dependent on arguments. The description is empty, lowering confidence, but the tool name and server context strongly imply active DNS enumeration execution.

From the tool's definition Tool name 'dnsenum_scan' suggests execution of the dnsenum tool, a DNS enumeration utility that performs active reconnaissance against targets. The server description mentions 'reconnaissance' and 'comprehensive security assessments'.
