WHAT IT DOES

What web_app_attack does on Bug Bounty Hunter MCP

AI agents invoke web_app_attack to trigger actions in Bug Bounty Hunter MCP. 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 web_app_attack needs a policy

This tool actively executes exploitation attacks against web applications. Even in a bug bounty context, it performs offensive security operations that can cause unintended damage, trigger WAFs, corrupt application state, or cause denial of service. The word 'Executes' combined with 'Exploitation' confirms this is an active attack tool, not passive reconnaissance.

From the tool's definition 'Executes focused Web Application Exploitation' — explicitly runs attack/exploitation operations against web applications
