Check if the device screen is locked
AI agents call adb_is_locked to retrieve information from Openclaw Adb without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only query of device lock status. It retrieves information about the current state of the Android device's screen lock without side effects, making it a Read category tool. The severity is low because knowing lock status poses minimal security risk—it provides no access to sensitive data and cannot cause harm or enable further attacks on its own.
From the tool's definition Tool name 'adb_is_locked' and description 'Check if the device screen is locked' indicate a query operation that retrieves device state without modifying or executing actions on the device.

Register the Openclaw Adb MCP server in PolicyLayer and add a rule for adb_is_locked: 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 Openclaw Adb. Nothing to install.
adb_is_locked 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 adb_is_locked 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 adb_is_locked. 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.
adb_is_locked is provided by the Openclaw Adb MCP server (wilsonbeam/openclaw-adb-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
