Dump the UI hierarchy using UIAutomator and return as XML
AI agents call android_uiautomator_dump 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 reads and retrieves the current UI hierarchy of the Android device, returning it as XML data. It performs no modifications, executions, or destructive operations. However, it has medium severity because the UI hierarchy can expose sensitive on-screen information (passwords, personal data, app states) that could be misused by an AI agent.
