3 MCP tools: drengr_look (observe screen), drengr_do (take action), drengr_query (ask questions)
Android & iOS — ADB for Android, simctl for iOS, Appium for cloud devices
Vision-first — sees your app like a human via annotated screenshots
Text mode — ~300 tokens per screen instead of 100KB images
Situation reports — after every action: what changed, what's new, is it stuck?
Screen exploration — auto-maps your app's navigation graph
Network capture — sees HTTP calls during each action
