Get the currently focused app and activity
AI agents call get_current_activity to retrieve information from Enhanced ADB MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about the currently active Android application and activity. It performs a read-only query of device state with no side effects, no code execution, no data modification, and no destructive operations. This is a standard diagnostic/inspection operation common in Android testing workflows.
From the tool's definition Tool name 'get_current_activity' and description 'Get the currently focused app and activity' indicate retrieval of state information without modification, deletion, or execution of commands.
Attacks that exploit this kind of access
Get the currently focused app and activity. It is categorised as a Read tool in the Enhanced ADB MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Enhanced ADB MCP Server MCP server in PolicyLayer and add a rule for get_current_activity: 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 Enhanced ADB MCP Server. Nothing to install.
get_current_activity 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_activity 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_activity. 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_current_activity is provided by the Enhanced ADB MCP Server MCP server (rahulkr/r_adb_mcp_server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
