In depth
An extension promoted to first-class status in the 2026-07-28 Model Context Protocol spec that lets a server return a sandboxed, server-rendered UI instead of only text. A tool can hand the client a real interface - a form, a table, a control panel - changing the design space from returning a string to returning an interaction. Because server-rendered UI is untrusted content, clients must render it in a sandbox.
