run_kali_command · Kali MCP Server MCP: Risk & Policy

WHAT IT DOES

What run_kali_command does on Kali MCP Server

AI agents invoke run_kali_command to trigger actions in Kali 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 run_kali_command needs a policy

run_kali_command triggers real processes with real consequences. An agent gone sideways doesn't fire it once — it starts dozens of builds, sends mass notifications, or burns through compute before anyone looks up.

run_kali_command Rate-limited
