WHAT IT DOES

What disk_smart_test_run does on Nasbridge

AI agents invoke disk_smart_test_run to trigger actions in Nasbridge. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why disk_smart_test_run is rated High

This tool triggers an external hardware diagnostic operation (SMART test) on physical disks. It executes a job/process rather than simply reading data or modifying configuration. While SMART tests are generally non-destructive, running them can impact disk performance and involves executing a background job on hardware devices.

From the tool's definition Run a SMART test on one or more disks. Returns a job ID for the test.

RECOMMENDED RULE

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

disk_smart_test_run Rate-limited

disk_smart_test_run stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
