adb_type_text · Openclaw Adb MCP: Risk & Policy

WHAT IT DOES

What adb_type_text does on Openclaw Adb

AI agents invoke adb_type_text to trigger actions in Openclaw Adb. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why adb_type_text needs a policy

This tool sends text input to an Android device via ADB, triggering an external operation (text injection) on the device. It can be misused to type into sensitive fields (passwords, messages, commands), but is not inherently destructive or financial. It falls under Execute as it triggers device-level actions whose effects depend on the arguments provided.
