Agent Droid Bridge
Gives your AI agent direct access to Android devices and emulators through ADB. You get 14 core tools for screen capture, UI inspection, touch input, text entry, and shell commands, plus an optional app_manager pack with 9 more for APK extraction, package management, and intent injection. Built for mobile QA automation, app testing, and security research where you need to tap, swipe, install, inspect permissions, or pull artifacts without modifying the target app. Runs in unrestricted mode with full ADB access or restricted mode with allowlists. Returns structured, minimal responses instead of raw XML dumps to keep context windows manageable during long automation sessions. Optional JSONL logging captures every tool call and security event.
