WHAT IT DOES

What unifi_list_devices does on UniFi Access MCP

AI agents call unifi_list_devices to retrieve information from UniFi Access MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why unifi_list_devices is rated Low

The 'list' verb combined with '_devices' suffix strongly indicates a read-only query operation that retrieves door/device state from the UniFi Access system. No side effects or data modification are implied. Confidence is slightly reduced due to empty description, but the naming pattern is unambiguous.

From the tool's definition Tool name 'unifi_list_devices' indicates a listing/querying operation; description is empty but naming convention and server context (UniFi Access management) suggests retrieval of device information without modification.

RECOMMENDED RULE

The rule that runs unifi_list_devices safely

unifi_list_devices Allowed

unifi_list_devices 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 UniFi Access MCP, apply this rule, and every unifi_list_devices call is checked against it from then on.
