WHAT IT DOES

What start_commix_session does on Pentester-MCP

AI agents invoke start_commix_session to trigger actions in Pentester-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.

RISK

Why start_commix_session is rated High

Commix is designed to discover and exploit command injection vulnerabilities by sending payloads that execute system commands on vulnerable targets. Starting a Commix session enables arbitrary command execution on remote systems, making this an Execute category tool. The blast radius is high because an AI agent could exploit unintended targets, escalate privileges, or cause significant damage.

From the tool's definition Tool name 'start_commix_session' refers to Commix, a command injection testing tool that executes arbitrary commands on target systems.

RECOMMENDED RULE

The rule that runs start_commix_session safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Pentester-MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For start_commix_session, this is the rule to start with:

start_commix_session Rate-limited

start_commix_session stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
