WHAT IT DOES

What inject_portscan does on Cobalt Strike MCP Server

AI agents invoke inject_portscan 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 inject_portscan needs a policy

Port scanning is an active network operation that probes external systems, fitting the Execute category. In the context of a Cobalt Strike red team server with beacon control, this tool injects and runs scanning code on or through a compromised beacon, making it a significant offensive capability.

From the tool's definition 'inject_portscan' and 'Perform port scan' — actively executes network reconnaissance by injecting and running a port scanning operation against target hosts
