Summary

Microsoft 365 Copilot Chat's MCP-based agents will support rich interactive UI widgets starting late February 2026, enhancing user interactions. Admins manage agents via Microsoft 365 Admin Center with existing controls and Entra ID group access. No action is required, but reviewing governance and documentation is advised.

More information

Updated March 3, 2026: We have updated the timeline. Thank you for your patience. 

Introduction

Model Context Protocol (MCP) based agents in Microsoft 365 Copilot Chat will now be able to surface rich, interactive UI widgets directly within chat. This enhancement enables developers to deliver more engaging and structured agent interactions. Users will experience these widgets when interacting with agents that implement them, and admins will continue to manage these agents through the Microsoft 365 Admin Center.

What will happen:

  • MCP-based agents can now display rich interactive UI widgets in Copilot Chat.
  • Widgets provide more guided, visual, and structured interactions.
  • Admins can deploy agents from the Agent Store or through custom MCP packages.
  • Existing Copilot extensibility controls remain unchanged.
  • Access to agents can continue to be scoped via Entra ID groups.
  • This functionality is enabled by default for agents that implement widgets.

What you can do to prepare:

No action is required.

  • Optionally review the Agents catalog for alignment with internal policies.

Before general availability rollout, we will update this post with new documentation.

Compliance considerations:

Question Explanation
Does the change provide end users any new way of interacting with generative AI? Users gain a new interaction model with MCP-based agents through embedded widgets such as buttons, selectors, and parameter controls. These provide a structured way to drive agent behavior and generative responses.
Does the change include an admin control and can it be controlled through Entra ID group membership? Admins continue to manage which MCP-based agents (including those with widget support) are available through Microsoft 365 Admin Center ā†’ Copilot ā†’ Agents, with access assignable using existing Entra ID group mechanisms.
