Why it matters
- Makers: Test exporting Power Apps as declarative agents so custom app tools can be invoked through MCP plugin actions.
- Makers: Validate rich MCP UI scenarios for app-based conversations while the capability remains in public preview.
- Admins/IT: Review tenant deployment of downloaded declarative agent packages before making app capabilities available in Microsoft 365 Copilot.
