Delete a TCP listener
AI agents call delete_listener_tcp to permanently remove resources in Cobalt Strike MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes a TCP listener—a network service endpoint used for red team operations. Deletion is irreversible and directly impacts operational infrastructure. While not as critical as compromising active beacons, destroying listener infrastructure disables command channels and cannot be undone without reconfiguration.
From the tool's definition Tool name is 'delete_listener_tcp' with description 'Delete a TCP listener'. The word 'Delete' indicates irreversible removal of infrastructure configuration.
