Generative UI and MCP Apps
Render an HTML app, a widget, or an action result inside Co-pilot and MCP hosts that support it.

A raw JSON payload is a poor way to review a result. Generative UI and MCP Apps let an agent show an interactive page in a host that supports it. Builders write templates in the Agents editor, including a full HTML document. MCP tools render action results, or a json-render spec, as widgets.
