Session Sneak Peek Part 4: UI5 has entered the chat – AI, MCP Apps and UI5 @marian.zeis.de & @mikezaschka.bsky.social are bringing this exciting session to the #UI5con2026 stage and this one will have everyone talking! #UI5 #AI #MCP
Sneak Peek: Sessions at UI5con 2026 Part 4.
Get a first look at the sessions our speakers are preparing for this year's UI5con.Session:
UI5 has entered the chat - AI, MCP Apps and UI5.

Speaker: Mike Zaschka & Marian ZeisThe hook 🎯


What if an LLM could do more than answer with text and open a real UI5-based app exactly when the user needs it?

The problem ❓

MCP tools are powerful, but for many developers it is still unclear how MCP Apps actually work: who calls the tool, where the UI comes from, how data reaches the app, and how fixed or flexible that UI can be.


The benefit ✅

In this session, we will build the topic step by step: from a minimal MCP App to UI5 Web Components and Integration Cards, ending with a real SAP transport review use case where ARC-1 provides the data and a MCP Apps visualizes it.Want more
Sneak Peeks?
Tell us in the comments: Which session or topic
should we feature next?
