dalfox · PenTest MCP Server MCP: Risk & Policy

WHAT IT DOES

What dalfox does on PenTest MCP Server

AI agents invoke dalfox to trigger actions in PenTest 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 dalfox needs a policy

Dalfox actively probes and attacks target web applications by injecting XSS payloads, triggering external HTTP requests and potentially exploiting vulnerabilities on live systems. This constitutes execution of security testing operations against external targets. Misuse could result in unauthorized attacks against systems not owned by the user, with high blast radius given the penetration testing context.
