WHAT IT DOES

What execute_rportfwd_stop does on Cobalt Strike MCP Server

AI agents invoke execute_rportfwd_stop 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_rportfwd_stop is rated High

This tool executes a command that terminates an active reverse port forwarding tunnel on a compromised beacon. While not destructive to persistent data, it is an active operation that changes system state and network connectivity. It belongs in Execute rather than Read because it performs an action with real-world effects (terminating network tunnels), not merely querying information.

From the tool's definition Tool is part of Cobalt Strike MCP Server which provides "beacon control" operations. The tool name 'execute_rportfwd_stop' indicates execution of a reverse port forwarding termination command.
