What rsync_task_list does on Truenas
AI agents call rsync_task_list to retrieve information from Truenas without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why rsync_task_list is rated Low
This tool performs a retrieval operation only—it lists rsync tasks without creating, modifying, deleting, or executing anything. The action is non-destructive and produces no side effects. Misuse would only expose information about configured rsync jobs, not affect any system operations.
From the tool's definition Tool name 'rsync_task_list' and description 'List all rsync tasks' indicate a read-only query operation that retrieves existing configuration data without modification.
Attacks that exploit this kind of access
The rule that runs rsync_task_list safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Truenas, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For rsync_task_list, this is the rule to start with:
rsync_task_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 Truenas, apply this rule, and every rsync_task_list call is checked against it from then on.
