List datasets with usage and quota info. Always specify a pool to avoid timeouts on large systems.
AI agents call list_datasets to retrieve information from Truenas Ws without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries dataset information (usage, quota details) without creating, modifying, or deleting any data. It is a read-only operation with no side effects beyond returning information to the caller. The guidance to 'specify a pool to avoid timeouts' reinforces that this is a safe query operation.
From the tool's definition Tool name 'list_datasets' and description 'List datasets with usage and quota info' indicate data retrieval with no modification capability.
Attacks that exploit this kind of access
List datasets with usage and quota info. Always specify a pool to avoid timeouts on large systems. It is categorised as a Read tool in the Truenas Ws MCP Server, which means it retrieves data without modifying state.
Register the Truenas Ws MCP server in PolicyLayer and add a rule for list_datasets: 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 Ws. Nothing to install.
list_datasets 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 list_datasets 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 list_datasets. 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.
list_datasets is provided by the Truenas Ws MCP server (thoriphes/truenas-ws-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
