MCP Apps - Bringing UI Capabilities To MCP Clients

MCP Apps are now live as an official MCP extension. Tools can now return interactive UI components that render directly in the conversation: dashboards, forms, visualizations, multi-step workflows, and more. This is the first official MCP extension, and it’s ready for production. We proposed MCP Apps last November, building on the amazing work of MCP-UI and the OpenAI Apps SDK. We were excited to partner with both OpenAI and MCP-UI to create a shared open standard for providing affordances for developers to include UI components in their MCP clients.
