Microsoft Copilot (Microsoft 365): Support for MCP Agents with Interactive UI Widgets in Government Clouds

🚨 The Signal: Microsoft 365 Copilot agents in GCC can now display interactive user interface widgets within chat. This enhances agent capabilities, potentially increasing data interaction points and the attack surface for agentic AI.

The Impact

Security teams and administrators are affected by new interactive agent capabilities, increasing the risk of data exposure or misuse if not properly governed.

• Security Teams: Increased risk of prompt injection or data exfiltration via new interactive agent surfaces.
• Administrators: Need to review and update policies for managing Copilot agents and their interactive capabilities.
• End Users: Potential for enhanced phishing or social engineering if malicious agents exploit interactive features.

The Action

1. Review existing Copilot agent governance policies for data handling and user interaction.
2. Assess the security posture of custom or third-party Copilot agents that leverage interactive widgets.
3. Educate users on identifying legitimate interactive agent widgets versus potential malicious attempts.
4. Monitor Copilot audit logs for unusual agent activity or data access related to interactive features.
