What privilege_delete does on Nasbridge
AI agents call privilege_delete to permanently remove resources in Nasbridge, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why privilege_delete is rated Critical
Deleting privileges or roles is a destructive operation that cannot be undone and directly impacts system security and user access controls. An AI agent misusing this tool could permanently revoke critical access permissions across the TrueNAS system, affecting multiple users or services. This warrants critical severity due to the irreversible nature and broad security implications.
From the tool's definition Tool name contains 'delete' and description explicitly states 'Delete a privilege/role by its ID.' This operation irreversibly removes access control configurations.
Attacks that exploit this kind of access
The rule that runs privilege_delete safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Nasbridge, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For privilege_delete, this is the rule to start with:
privilege_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 Nasbridge, apply this rule, and every privilege_delete call is checked against it from then on.
Questions about privilege_delete
Delete a privilege/role by its ID. Use privilege_list to find the ID. It is categorised as a Destructive tool in the Nasbridge MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Nasbridge MCP server in PolicyLayer and add a rule for privilege_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 Nasbridge. Nothing to install.
privilege_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 privilege_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 privilege_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.
privilege_delete is provided by the Nasbridge MCP server (maverick0628/nasbridge). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
