What iscsi_target_list does on Nasbridge
AI agents call iscsi_target_list to retrieve information from Nasbridge without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why iscsi_target_list is rated Low
This is a straightforward information retrieval operation. It queries and returns data about iSCSI targets on the TrueNAS SCALE instance with no side effects, no data modification, and no irreversible actions. The blast radius of misuse is minimal—an agent could only view configuration details of existing targets.
From the tool's definition The tool name is 'iscsi_target_list' and the description states 'List all iSCSI targets'. The verb 'list' indicates a read-only query operation that retrieves information about existing iSCSI targets without modifying, deleting, or executing any actions.
Attacks that exploit this kind of access
The rule that runs iscsi_target_list safely

iscsi_target_list is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Nasbridge, apply this rule, and every iscsi_target_list call is checked against it from then on.
