## Why delete_listener_tcp is rated Critical

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 own definition: "Tool name is 'delete_listener_tcp' with description 'Delete a TCP listener'. The word 'Delete' indicates irreversible removal of infrastructure configuration."

## Use case

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.

## Recommended policy (PolicyLayer)

Verdict: **Hidden**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Cobalt Strike MCP Server:

```json
{
  "version": "1",
  "default": "deny",
  "hide": [

  ]
}
```
