Release: http://blog.modelcontextprotocol.io/posts/2026-01-26-mcp-app... . Announcement: http://blog.modelcontextprotocol.io/posts/2025-11-21-mcp-app... . Submission: https://news.ycombinator.com/item?id=46020502
But our use case is a little different. MCP Apps embed interfaces into other agents. Tambo is an embedded agent that can render your UI. There's overlap for sure, but many of the developers using us don't see themselves putting their UI inside ChatGPT or Claude. That's just not how users use their apps.
That said, we're thinking about how we could make it easy to build an embedded agent and then selectively expose those UI elements over MCP Apps where it makes sense.
