Foundry Agent Service and A2A support already active?

[michelschep]

According to several Microsoft blog posts the Foundry Agent Service is supporting the A2A protocol:
https://techcommunity.microsoft.com/blog/azure-ai-services-blog/building-a-digital-workforce-with-multi-agents-in-azure-ai-foundry-agent-service/4414671

But is A2A support for Foundry Agents really already available?

To test the A2A protocol I created a simple Foundry Agent and tried to retrieve the Agent Card (with the /.well-known/agent.json path).
No success (I used the a2a dotnet implementation from: https://github.com/a2aproject/a2a-dotnet).
It looks like the /.well-known/agent.json does not exist.

When using the generated code (in the foundry playground) I'm able to execute the agent (so network or authentication is no issue).

Anybody already successfully succeeded to connect to and execute a Foundry Agent with A2A?

The Foundry-specific A2A SDK is not yet available. However, you can use the official A2A SDK as a workaround to establish the connection you need.

Workaround Available:

I've added working examples to help you get started:

📁 Examples: https://github.com/a2aproject/a2a-samples/tree/main/samples/python/agents/azureaifoundry_sdk

These samples demonstrate how to integrate with Azure AI Foundry using the current A2A SDK implementation.

Thx! So it is basically a A2A wrapper around the Foundry Agent interface to be able to use the foundry agent in a A2A environment.
