Integration overview
How it connects to OpenUI
Mastra owns the agent and tools, the AG-UI transport serializes the run as SSE, and OpenUI's agUIAdapter drives AgentInterface and the component renderer on the client.
The integration path
- 1
Describe the interface
Generate a component prompt from the same OpenUI library that will render the response.
- 2
Stream structured output
Let Mastra own its part of the stack while OpenUI Lang travels as incremental text or mapped agent events.
- 3
Render and interact
Parse the stream with the matching OpenUI runtime, render real components, and return validated actions to the application.
What stays consistent
One schema for prompting and rendering
Progressive rendering while output streams
Typed components instead of arbitrary markup
Host application retains its runtime behavior
