Yeah, there's a ton of great improvements in 7-28. I'm personally excited about what you posted about, but also with [tasks](https://blog.modelcontextprotocol.io/posts/2026-07-28-release-candidat… being officially adopted.

Looks like OpenAI, Anthropic, and the MCP-UI team actually worked together on a common standard for MCP Apps: https://blog.modelcontextprotocol.io/posts/2025-11-21-mcp-apps/
Honestly, I think the biggest friction for MCP adoption has been how un-userfriendly it is. It’s great for devs, but not the average users. Users don't always want to chat, sometimes they just want to click a button or adjust a slider. This feels like the answer to that problem.
Full disclosure, I'm partial here because of our work at https://usefractal.dev. We were early adopters when MCP first came out, but we always felt like something was missing. We kept wishing for a UI layer on top, and everyone says it's gonna take forever for the industry to adopt, maybe months, maybe years.
I cannot believe the adoption comes so quickly. I think this is gonna be huge. What do you guys think?

It’s going to be built into MCP and will be supported by Anthropic and OpenAI or anyone else that supports this mcp spec

MCP is never the right choice.
If you want to build an AI app that lets people “do random thing here”, then build an app.
Peak MCP is people trying to write a declarative UI as part of the MCP spec (1, I’m not kidding); which is “tldr; embed a webview of a web app and call it MCP”.
MCP is just “me too”; people want MCP to be an “AI App Store”; but the blunt, harsh reality is that it’s basically impossible to achieve that dream; that any MCP consumer can have the same app like experience for installed apps.
Seriously, if we can barely do that for browsers which have a consistent ui, there was never any hope even remotely that it would work out for the myriad of different MCP consumer apps.
It’s just stupid. Build a web app or an API.
You don’t need an MCP sever; agents can very happily interact with higher level functions.
