Teams can now build and deploy MCP Apps on Vercel with full support for Next.js.

MCP Apps are similar to [ChatGPT apps](/changelog/chatgpt-apps-support-on-vercel), but are a provider-agnostic open standard for embedded UIs. They run inside iframes and communicate with any compatible host, such as Cursor, Claude.ai, and 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.
