Teams can now build and deploy MCP Apps on Vercel with full support for Next.js.
MCP Apps are similar to ChatGPT apps, but are a provider-agnostic open standard for embedded UIs. They run inside iframes and communicate with any compatible host, such as ChatGPT, using a shared bridge.
This architecture uses ui/* JSON-RPC over postMessage, enabling a single UI to function across any compatible host without platform-specific integrations.
By combining this standard with Next.js on Vercel, developers can leverage Server-Side Rendering (SSR) and React Server Components to build portable, high-performance agent interfaces.
