commix · PenTest MCP Server MCP: Risk & Policy

WHAT IT DOES

What commix does on PenTest MCP Server

AI agents invoke commix 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 commix needs a policy

Commix (Command Injection Exploiter) doesn't merely scan passively; it actively attempts to exploit command injection vulnerabilities by injecting and executing OS commands on target systems. This constitutes remote code execution capability.

From the tool's definition Command injection vulnerability scanner — 'commix' is a well-known automated command injection exploitation tool that actively probes and exploits command injection vulnerabilities on target systems, executing OS-level commands remotely.
