What rsync_task_delete does on Truenas
AI agents call rsync_task_delete to permanently remove resources in Truenas, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why rsync_task_delete is rated Critical
This tool irreversibly removes a configured rsync task from TrueNAS. Deletion of system tasks is a destructive operation that cannot be undone and could cause data synchronization to halt unexpectedly if an agent deletes critical backup or replication tasks. While not as severe as deleting data itself, it permanently removes configuration state.
From the tool's definition Tool name explicitly states 'delete' and description confirms 'Delete an rsync task'. Rsync tasks are configured synchronization jobs that, once deleted, cannot be recovered without manual reconfiguration.
Attacks that exploit this kind of access
The rule that runs rsync_task_delete 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_delete, this is the rule to start with:
rsync_task_delete is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect Truenas, apply this rule, and every rsync_task_delete call is checked against it from then on.
Questions about rsync_task_delete
Delete an rsync task. It is categorised as a Destructive tool in the Truenas MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Truenas MCP server in PolicyLayer and add a rule for rsync_task_delete: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Truenas. Nothing to install.
rsync_task_delete is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the rsync_task_delete rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for rsync_task_delete. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
rsync_task_delete is provided by the Truenas MCP server (spranab/truenas-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
