We Want MCP UI SDK for Java

[Praveenduddu]

We would like to request an official MCP UI SDK for Java that provides first-class support for building user interfaces powered by the Model Context Protocol (MCP). Java remains widely used in enterprise, desktop, and embedded environments, and having a native UI SDK would greatly expand MCP’s accessibility and adoption across these ecosystems.

This SDK's prime goal is to help write web apps that turn into iframed / WebView-embedded applets in conversational chatbots. Java probably wouldn't be used for the web app part, and we weren't really intending to provide a production hosting SDK (the examples only have a basic host example, we expect projects such as MCP-UI or complete custom reimplementations might be used instead).

That said we could maybe think of adding an official AppBridge implementation for Java and other langs. Any OSS Java MCP clients you have in mind to use this in?
