WHAT IT DOES

What empire_agents does on PowerShell Empire MCP Server

AI agents invoke empire_agents to trigger actions in PowerShell Empire 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 empire_agents needs a policy

Empire agents represent active command-and-control sessions on compromised systems. Managing agents implies the ability to task, interact with, or control remote shells on victim machines. This is inherently an Execute-level capability with critical blast radius, as misuse allows arbitrary remote code execution across all active agent sessions.

From the tool's definition 'manage active Empire agents' on a PowerShell Empire C2 framework — agents are remote shells on compromised hosts
