WHAT IT DOES

What dataset_encryption_summary does on Truenas

AI agents call dataset_encryption_summary 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_encryption_summary is rated Low

This tool retrieves and displays encryption metadata for datasets. The verb 'Get' and the use of 'summary' clearly indicate a read operation with no side effects. It does not create, modify, delete, or execute any operations—it only queries and returns information about existing dataset encryption states.

RECOMMENDED RULE

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

dataset_encryption_summary Allowed

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

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_encryption_summary call is checked against it from then on.
