WHAT IT DOES

What linpeas does on MCP Kali Pentest

AI agents invoke linpeas to trigger actions in MCP Kali Pentest. 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 linpeas needs a policy

LinPEAS is a well-known script that runs on a target Linux system to enumerate potential privilege escalation vectors. It executes code on the system, scans configurations, reads sensitive files, and identifies misconfigurations. In the context of a penetration testing framework, misuse could expose sensitive system information or be used as a precursor to full system compromise.
