Clear all indicators from the clock.
AI agents call clear_indicators to permanently remove resources in Ulanzi — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
'Clear all indicators' is an irreversible removal of all indicator data currently displayed on the device. While the blast radius is limited to visual indicators on a smart pixel clock (no data loss beyond display state), the action is not easily undoable without re-creating each indicator individually, making it Destructive rather than Write.

Attacks that exploit this kind of access
Clear all indicators from the clock. It is categorised as a Destructive tool in the Ulanzi MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Ulanzi MCP server in PolicyLayer and add a rule for clear_indicators: 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 Ulanzi. Nothing to install.
clear_indicators is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the clear_indicators 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 clear_indicators. 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.
clear_indicators is provided by the Ulanzi MCP server (jelloeater/ulanzi-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
