WHAT IT DOES

What execute_beacon_command does on Cobalt Strike MCP Server

AI agents invoke execute_beacon_command 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.

RISK

Why execute_beacon_command is rated High

This tool directly executes arbitrary commands on remote beacons in a red team framework. While it is not itself destructive or financial, it enables arbitrary code execution whose effects are entirely dependent on attacker-supplied arguments.

From the tool's definition Tool name 'execute_beacon_command' and description states it 'Execute[s] a command on a beacon'. The Cobalt Strike context indicates this triggers remote code execution on compromised targets.
