WHAT IT DOES

What ligolo_proxy_start does on Ligolo-ng MCP Server

AI agents invoke ligolo_proxy_start to trigger actions in Ligolo-ng 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 ligolo_proxy_start needs a policy

Starting a proxy server is an Execute action: it launches a process that initiates network operations and tunnel management. While not immediately destructive or financial, the blast radius is high because an attacker controlling this tool could establish unauthorized network pivots, intercept traffic through managed tunnels, or enable lateral movement in a compromised network during a security assessment.

From the tool's definition Tool description states it 'Start[s] the ligolo-ng proxy server' which triggers external network operations.
