Find UI elements containing specific text.
AI agents call find_element_by_text 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 is a pure read operation that inspects the UI hierarchy to locate elements by their text content. It retrieves information about the visual state of an Android app without modifying, executing, or destroying anything. It falls clearly into the Read category. Severity is low because misuse (e.g., searching for sensitive text in UI) poses minimal risk compared to tools that execute code or modify state.
From the tool's definition Tool name and description indicate it 'Find[s] UI elements containing specific text' — a query/search operation with no side effects on the device or application state.
