A2UIAgent: Rich UI from Your AG2 Agents
Your AG2 agent can reason, call tools, and stream text. But what if it could also generate a full UI — cards, forms, buttons, images — from a single prompt?
A2UIAgent is a new reference agent in AG2 that produces rich, interactive user interfaces using the A2UI protocol. Instead of returning plain text, the agent generates structured JSON that client-side renderers transform into native UI components. The same agent serves web, mobile, and desktop clients — all through standard protocols.
In this post, we'll walk through what A2UIAgent does, how it works under the hood, and how to build a working demo that generates marketing preview cards served over A2A.
