WHAT IT DOES

What dataset_get_quota does on Truenas

AI agents call dataset_get_quota 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.

RISK

Why dataset_get_quota is rated Low

This tool queries existing quota information for datasets, users, groups, or projects. It retrieves data without modifying, deleting, or executing external operations. The blast radius of misuse is minimal—an agent could only view quota information to which it has access, with no ability to change quotas, delete data, or impact system state.

From the tool's definition Tool name 'dataset_get_quota' and description 'Get dataset quotas' indicate a retrieval operation with no side effects. The verb 'Get' and lack of any create/modify/delete language confirm read-only semantics.

RECOMMENDED RULE

The rule that runs dataset_get_quota 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 dataset_get_quota, this is the rule to start with:

dataset_get_quota Allowed

dataset_get_quota is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

  "default": "deny",
  "tools": {
    "dataset_get_quota": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Truenas, apply this rule, and every dataset_get_quota call is checked against it from then on.
