List all privileges/roles configured on the system.
AI agents call privilege_list to retrieve information from Truenas without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves and lists existing privilege and role configurations. It performs no side effects, creates no data, executes no commands, and makes no changes to system state. It is a straightforward read operation that falls clearly into the 'Read' category with low severity since reading privilege information alone poses minimal risk without accompanying write or execute capabilities.
From the tool's definition Tool name is 'privilege_list' and description states 'List all privileges/roles configured on the system' - a pure query/retrieval operation with no modification, deletion, or execution.
Documented attack patterns abuse exactly the kind of access privilege_list gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Truenas, and nothing reaches the server without passing your rules. This is the rule we recommend for privilege_list:
{
"version": "1",
"default": "deny",
"tools": {
"privilege_list": {}
}
}privilege_list is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all privileges/roles configured on the system. It is categorised as a Read tool in the Truenas MCP Server, which means it retrieves data without modifying state.
Register the Truenas MCP server in PolicyLayer and add a rule for privilege_list: 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.
privilege_list is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the privilege_list 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_list. 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_list 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.
Start from Truenas, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
