Dedicated environment to manage agents with REST API actions in the Copilot Studio Agent Builder [MC1045175]

We are introducing the capability to manage agents using REST API actions developed with Copilot Studio Agent Builder in Microsoft 365 Copilot, within a new dedicated Microsoft Power Platform environment. This feature will reach general availability on April 28, 2025.

How does this affect me?
With this change, admins will be able to do the following:

• Govern their new dedicated Copilot Studio Agent Builder environment via the Power Platform admin center.
• Set a data loss prevention policy for custom actions to apply rules against specific URL patterns. When a policy is applied to the “Copilot Studio agent builder” environment, agents cannot connect to the external service.

In addition, the agent builder is informed that the action is blocked while creating the agent; thus, creating and making updates to existing agents are blocked.

To provide admins ample time to set up these policies, we are placing an automatic sharing limit on agents that have activated a REST API action. If the agent has at least one active REST API action, the agent’s sharing options will be restricted to “Only you”. This automatic sharing limit only applies to Copilot Studio Agent Builder and will be valid for a limited time . Users can turn all active actions off or remove the connector to share the agent with more users.

What do I need to do to prepare?
This message is for awareness and no action is required.
