MCP Apps - Bringing UI Capabilities To MCP Clients
Today, we’re announcing that 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.
