## AI overview

The article examines MCP Apps, an extension of the Model Context Protocol, alongside the protocol's 2026-07-28 changes. It explains how MCP Apps let servers return isolated, interactive, stateful UIs that clients such as ChatGPT can embed in agent responses, with examples including dashboards, data tables, and forms.
