What list_remote_clients does on Claude C2
AI agents call list_remote_clients to retrieve information from Claude C2 without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why list_remote_clients is rated Low
This tool retrieves/queries information about remote clients without modifying state. However, the 'medium' severity reflects that the information exposed (list of connected remote clients) could be sensitive reconnaissance data useful for lateral movement or privilege escalation in an adversarial context, particularly given the context of other tools on this server (amsi_bypass, bypassuac, defender_exclude)…
From the tool's definition Tool name and description indicate retrieval of connected client information: 'List all connected remote clients'. The description uses 'List', a read operation verb, and contains no language suggesting modification, deletion, or execution.
Attacks that exploit this kind of access
The rule that runs list_remote_clients safely

list_remote_clients is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
