Phone demos.
Real frames.
USB mirror with portable ADB, auto device shells, 9:16 layout, and the same zoom / captions polish as desktop takes.
Works with vibe coding agents over MCP
The problem
Every demo starts from scratch.
Re-doing android usb by hand on every take
Opening a full editor for a thirty-second demo
Agents that capture clicks but leave the polish to you
The fix
Android USB is built into the studio, not bolted on later.
01USB mirror
Desktop installs portable ADB once, lists devices, and mirrors without owning every port forever.
02Model detection
Pixel, Galaxy, OnePlus, Xiaomi, and generic shells with colorways that match the phone you filmed.
03Portrait layout
Phone mode clears desktop chrome, tightens padding, and reframes so social cuts don’t letterbox wrong.
Full USB mirroring ships with the Windows desktop app. See Pro →
In the studio
The real Screen Beaver UI, Android USB selected.
Rail, inspector, stage, and timeline, the same chrome you get in the Windows desktop app.
Set up once & you’re done.
Install the Windows app first, then MCP, then your agent.
01 Install the app
Download Screen Beaver for Windows. MCP only works after the software is installed and running.
Microsoft Store → install → leave open
02 Wire MCP
Install the CLI, then point any MCP-capable coding agent at Screen Beaver.
$ npm i -g @screenbeaver/mcp
03 Ship the demo
Android USB lands on the timeline, export locally.
Same demo. Different finish.
Toggle android usb on, watch Screen Beaver do the polish work between a raw take and a shippable cut.
