Using AG-UI with Foundry Hosted Agents

[shamal-kp]

Hi!

I would like to deploy a hosted agent to Foundy. It will mainly just have some local code tools, but I want to take advantage of the observability, session storage and scaling features etc that follows on the platform.

I would also like to access this agent from a CopilotKit frontend, so I need the agent to be able to respond in AG-UI events. Is there a clean or right way to do this? Because the AgentFrameworkAgent from agent_framework.ag_ui seems incompatible with the one from azure.ai.agentserver.core that wraps it in a FoundryCBAgent.

Can I just deploy my agent to Foundry with the tools available and then add a AG-UI FastAPI application that proxies to the Foundry agent over REST? It's another proxy service in addition to the Copilotkit Runtime, but maybe it doable. So basically running both these apps servers and make them communicate over REST? Or am I overthinking this?

For reference it's mainly the functionality of the boilerplate Starlette/FastAPI from these two functions that I want to integrate:

from azure.ai.agentserver.agentframework import from_agent_framework
from agent_framework.ag_ui import add_agent_framework_fastapi_endpoint
