What it is and what it does
Agent Framework AG-UI is a protocol bridge that lets you expose Agent Framework agents and workflows through a web interface via FastAPI. It handles the AG-UI streaming protocol, allowing you to build servers that host AI agents or multi-step workflows and clients that connect to them over HTTP with streaming support. The package provides high-level helpers like `add_agent_framework_fastapi_endpoint` to wire up a FastAPI app, `AGUIChatClient` for async client connections, and utilities like `state_update` for tools that need to send different payloads to the model, the UI, and shared state.
The package depends on fastapi, httpx, uvicorn, sse-starlette, and agent-framework-core, plus the ag-ui-protocol specification. It supports both simple agent hosting and stateful workflow patterns (including thread-scoped workflows for conversation isolation). It implements the canonical AG-UI interrupt protocol for tool approval and workflow input requests, allowing paused runs to be resumed with user decisions or edited arguments.
Use it for
- Host an AI agent behind a FastAPI server and connect to it from a web client using AGUIChatClient with streaming responses.
- Build a multi-step workflow with AG-UI and expose it through a FastAPI endpoint for remote execution and state management.
- Implement tool approval workflows where the UI pauses execution, collects user approval or edited arguments, and resumes the agent.
- Create thread-scoped workflow instances to isolate conversation state and pending interrupts per user session.
- Render custom UI components for tool results using state_update to separate LLM-bound text from frontend-specific payloads.
