WHAT IT DOES

What generate_stager_payload does on Cobalt Strike MCP Server

AI agents invoke generate_stager_payload to trigger actions in Cobalt Strike 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 generate_stager_payload needs a policy

This tool generates offensive security payloads (stagers) used in red team/adversarial operations. A stager is executable malicious code that, when deployed, connects back to a Cobalt Strike listener to download and execute a full beacon implant. While the act of generating a payload is technically a Write operation, the payload itself is designed to execute arbitrary code on target systems.
