# Agent Framework AG-UI Integration

AG-UI protocol integration for Agent Framework, enabling seamless integration with AG-UI's web interface and streaming protocol.

## Installation

```bash
pip install agent-framework-ag-ui
```

## Quick Start

### Server (Host an AI Agent)

```python
from fastapi import FastAPI
from agent_framework import ChatAgent
from agent_framework.azure import AzureOpenAIChatClient
from agent_framework.ag_ui import add_agent_framework_fastapi_endpoint

# Create your agent
agent = ChatAgent(
    name="my_agent",
    instructions="You are a helpful assistant.",
    chat_client=AzureOpenAIChatClient(
        endpoint="https://your-resource.openai.azure.com/",
        deployment_name="gpt-4o-mini",
        api_key="your-api-key",
    ),
)

# Create FastAPI app and add AG-UI endpoint
app = FastAPI()
add_agent_framework_fastapi_endpoint(app, agent, "/")

# Run with: uvicorn main:app --reload
```

### Client (Connect to an AG-UI Server)

```python
import asyncio
from agent_framework import TextContent
from agent_framework.ag_ui import AGUIChatClient

async def main():
    async with AGUIChatClient(endpoint="http://localhost:8000/") as client:
        # Stream responses
        async for update in client.get_streaming_response("Hello!"):
            for content in update.contents:
                if isinstance(content, TextContent):
                    print(content.text, end="", flush=True)
        print()

asyncio.run(main())
```

The `AGUIChatClient` supports:
- Streaming and non-streaming responses
- Hybrid tool execution (client-side + server-side tools)
- Automatic thread management for conversation continuity
- Integration with `ChatAgent` for client-side history management

## Documentation

- **[Getting Started Tutorial](getting_started/)** - Step-by-step guide to building AG-UI servers and clients
  - Server setup with FastAPI
  - Client examples using `AGUIChatClient`
  - Hybrid tool execution (client-side + server-side)
  - Thread management and conversation continuity
- **[Examples](agent_framework_ag_ui_examples/)** - Complete examples for AG-UI features

## Features

This integration supports all 7 AG-UI features:

1. **Agentic Chat**: Basic streaming chat with tool calling support
2. **Backend Tool Rendering**: Tools executed on backend with results streamed to client
3. **Human in the Loop**: Function approval requests for user confirmation before tool execution
4. **Agentic Generative UI**: Async tools for long-running operations with progress updates
5. **Tool-based Generative UI**: Custom UI components rendered on frontend based on tool calls
6. **Shared State**: Bidirectional state sync between client and server
7. **Predictive State Updates**: Stream tool arguments as optimistic state updates during execution

## Security: Authentication & Authorization

The AG-UI endpoint does not enforce authentication by default. **For production deployments, you should add authentication** using FastAPI's dependency injection system via the `dependencies` parameter.

### API Key Authentication Example

```python
import os
from fastapi import Depends, FastAPI, HTTPException, Security
from fastapi.security import APIKeyHeader
from agent_framework import ChatAgent
from agent_framework.ag_ui import add_agent_framework_fastapi_endpoint

# Configure API key authentication
API_KEY_HEADER = APIKeyHeader(name="X-API-Key", auto_error=False)
EXPECTED_API_KEY = os.environ.get("AG_UI_API_KEY")

async def verify_api_key(api_key: str | None = Security(API_KEY_HEADER)) -> None:
    """Verify the API key provided in the request header."""
    if not api_key or api_key != EXPECTED_API_KEY:
        raise HTTPException(status_code=401, detail="Invalid or missing API key")

# Create agent and app
agent = ChatAgent(name="my_agent", instructions="...", chat_client=...)
app = FastAPI()

# Register endpoint WITH authentication
add_agent_framework_fastapi_endpoint(
    app,
    agent,
    "/",
    dependencies=[Depends(verify_api_key)],  # Authentication enforced here
)
```

### Other Authentication Options

The `dependencies` parameter accepts any FastAPI dependency, enabling integration with:

- **OAuth 2.0 / OpenID Connect** - Use `fastapi.security.OAuth2PasswordBearer`
- **JWT Tokens** - Validate tokens with libraries like `python-jose`
- **Azure AD / Entra ID** - Use `azure-identity` for Microsoft identity platform
- **Rate Limiting** - Add request throttling dependencies
- **Custom Authentication** - Implement your organization's auth requirements

For a complete authentication example, see [getting_started/server.py](getting_started/server.py).

## Architecture

The package uses a clean, orchestrator-based architecture:

- **AgentFrameworkAgent**: Lightweight wrapper that delegates to orchestrators
- **Orchestrators**: Handle different execution flows (default, human-in-the-loop, etc.)
- **Confirmation Strategies**: Domain-specific confirmation messages (extensible)
- **AgentFrameworkEventBridge**: Converts Agent Framework events to AG-UI events
- **Message Adapters**: Bidirectional conversion between AG-UI and Agent Framework message formats
- **FastAPI Endpoint**: Streaming HTTP endpoint with Server-Sent Events (SSE)
