WHAT IT DOES

What generate_stageless_payload does on Cobalt Strike MCP Server

AI agents invoke generate_stageless_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_stageless_payload needs a policy

Generating a stageless payload produces a fully self-contained malicious executable that, when deployed, establishes a C2 beacon. This is an offensive capability with critical blast radius: misuse by an AI agent could result in creation and distribution of malware, full host compromise, and lateral movement across networks.

From the tool's definition 'Generate a stageless payload for a listener' — creates a self-contained offensive payload for Cobalt Strike red team operations, part of a suite of 200+ beacon control and payload generation tools
