Agent Playground · Live

Your agent. Our UI. Live.

Start a session, connect your own agent over MCP, and watch it author Fancy UI screens + live data — calling screens_create to spin up surfaces, then driving each one with its per-kind tools. No external agent? Use the in-page console below to drive the same surface.

Connect your own agent
Open a relay session, then point any MCP client at it. Frames stream both ways — your agent inhabits the canvas, you ride shotgun.

Generates a session id + secret token. Hand the Agent prompt to an AI agent, share the URL with humans, or give the JSON config to an MCP-capable client.

C
The canvas is yours to inhabit

Open a session and ask your agent to screens_create a surface — or use the console to drop one in yourself. Screens render right here on the grid.
