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.
