Limpa dados do app alvo com pm clear em safe mode.
AI agents call clear_app_data to permanently remove resources in AVD MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The pm clear command on Android permanently wipes an application's data directory, including databases, preferences, cache, and user files. This is an irreversible operation that cannot be undone through normal means. While limited to a single app's scope (reducing blast radius compared to system-level destructive operations), it permanently destroys user data and application state.
From the tool's definition Tool uses 'pm clear' command which irreversibly deletes application data. The description states 'Limpa dados do app alvo' (clears target app data) in safe mode, which is a permanent data deletion operation.
