Microsoft has added the ability to easily connect to other agents from Copilot Studio. You can add child agents or other Copilot Studio Agents. What’s new is that you can now also add external agents. Fabric Agents, Foundry Agents and A2A protocol agents are now available in public preview.

Any agent you add will show up under the agents tab in your agent.

Connect to a Microsoft Foundry agent

To connect to a Microsoft Foundry agent all you have to do is navigate to the Agents tab in Copilot Studio (or click “Add agent” form the agents box on the Overview tab), click add and then select Microsoft Foundry from the “Connect to an external agent” list.

On the Connect Microsoft Foundry agent screen you need to create a new connection or select one if you have already created a connection to your Microsoft Foundry project.

To connect to Microsoft Foundry you will need the endpoint address for you Microsoft Foundry project, you can find that on your Microsoft Foundry homepage.

Copy the URL from the Project endpoint box and paste that into the Azure AI Project Endpoint box to connect to the Microsoft Foundry Project. Click create and log in with your credentials. When the connection is made click next.

On the next screen you will fill in information about your connected agent.

Give your agent connection a name and a description. Probably a good practice to give it a name describing its function and a description about what tasks it can perform. This will give your Copilot Studio the information it needs to understand when to call on this Microsoft Foundry agent.

I gave mine the name “Return policies” and a description of “Use this agent to answer questions related to cancellation of sessions or return of items”.

The Agent Id is the name of your agent from Microsoft Foundry, you can find that from the agents list in your Microsoft Foundry project. In my case the name is AAAPhotography.
