AI agents call get_apps_in_loop to retrieve information from Ulanzi without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries the current state of the display rotation loop to retrieve a list of apps. It performs a read-only operation that does not modify, delete, or execute any actions on the device. The blast radius of misuse is minimal—an AI agent could only retrieve information about which apps are active, with no ability to change settings or trigger unintended operations.
From the tool's definition Tool name 'get_apps_in_loop' and description 'Get list of all apps in the display rotation loop' indicate a retrieval operation with no side effects.

Get list of all apps in the display rotation loop. It is categorised as a Read tool in the Ulanzi MCP Server, which means it retrieves data without modifying state.
Register the Ulanzi MCP server in PolicyLayer and add a rule for get_apps_in_loop: 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.
get_apps_in_loop 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 get_apps_in_loop 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 get_apps_in_loop. 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.
get_apps_in_loop 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.
