Get the currently focused app (package + activity).
AI agents call get_current_app to retrieve information from Android MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool simply queries and returns the current foreground application's package name and activity. It performs no modifications, deletions, or external operations—purely informational retrieval. The blast radius of misuse is minimal: an agent learning which app is displayed poses no direct harm.
From the tool's definition Tool name 'get_current_app' and description 'Get the currently focused app (package + activity)' indicate a read-only query operation that retrieves application state without modifying anything.

Register the Android MCP Server MCP server in PolicyLayer and add a rule for get_current_app: 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 Android MCP Server. Nothing to install.
get_current_app 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_current_app 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_current_app. 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.
