AI BriefingVercel Supports MCP Apps
Key point
Vercel now supports building and deploying MCP Apps using Next.js.
Details
Vercel has begun supporting the building and deployment of MCP Apps through Next.js.
MCP Apps is an open standard for embedded UI that is not tied to any specific platform. It runs inside an iframe and communicates with compatible hosts such as Cursor, Claude.ai, and ChatGPT through a shared bridge.
This architecture uses a ui/* JSON-RPC approach via postMessage. This allows a single UI to work across various hosts without separate platform-specific integrations.
Developers can combine this with Vercel's Next.js to leverage Server-Side Rendering (SSR) and React Server Components, enabling them to build highly portable and performant agent interfaces.
