💡 Our Technical Review in summary
Summary
- Microsoft is introducing rich, interactive UI widget support for Model Context Protocol (MCP) based agents within Microsoft 365 Copilot Chat.
- This update allows developers to move beyond text-only interactions by embedding structured elements such as buttons, selectors, and parameter controls directly into the chat interface.
- The Public Preview is scheduled to begin in late February 2026 and is expected to reach completion by early March 2026.
Impact
- For End Users: Users will experience a more guided and visual interface when interacting with MCP-based agents. Widgets will simplify complex tasks by providing structured options instead of requiring purely natural language prompts for every action.
- For IT Administrators: Management of these agents remains consistent with existing workflows. Admins can continue to oversee agent deployment through the Microsoft 365 Admin Center under the Copilot settings.
- Governance and Security: Existing extensibility controls are unchanged. Access to specific agents can still be restricted or granted using Microsoft Entra ID group membership.
- Default Behavior: This functionality will be enabled by default for any MCP-based agents that have been programmed to include these interactive UI components.
Action Required
- No immediate action is required as the rollout will occur automatically for supported agents.
- Review Agent Catalog: Administrators should review the current Agents catalog to ensure available agents align with organizational data and interaction policies.
- Audit Governance Controls: Verify that current Microsoft 365 Copilot and agent governance settings are correctly configured in the Admin Center.
- Update Documentation: Internal training materials or IT support FAQs may need to be updated to reflect the new visual elements users will see in Copilot Chat.
- Stay Informed: Monitor the Microsoft 365 Message Center for future updates and official technical documentation closer to the General Availability (GA) date.

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.

When this will happen:
- Public Preview: Rollout will begin late February 2026 and is expected to complete by early March 2026.
How this affects your organization:
Who is affected:
- Organizations using Microsoft Copilot agents.
- Administrators responsible for agent governance and controls.
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.
- Review existing Copilot and agent governance controls.
- Update internal documentation as needed.
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 → Copilot → Agents, with access assignable using existing Entra ID group mechanisms. |
