#typescript MCP Apps is a stable standard (version 2026-01-26) that lets MCP servers show interactive UIs like charts, forms, maps, 3D scenes, and dashboards right in AI chats such as Claude or ChatGPT. Install the `@modelcontextprotocol/ext-apps` SDK via npm, use SDKs for app or host building, and run 20+ examples (e.g., budget tools, PDF viewers, real-time monitors) locally or in clients. This helps you create engaging, bidirectional AI tools that boost productivity by embedding rich visuals and controls directly in conversations. https://github.com/modelcontextprotocol/ext-apps
