MCP Apps: Primitives, discovery, and the Future of Software

on YouTube ↗29m

" summary

Claims that MCP Apps are a bidirectional, stateful UI layer backed by concrete primitives: ui/update-model-context, ui/message, App Tools. Architecture uses ui:// resources, sandboxed iframes and JSON‑RPC‑over‑postMessage; mcp-use SDK and Manufact cloud exist with 8M+ downloads. Demos include Excalidraw streaming tokens into a live canvas and a Remotion video rendered in-widget, both working in practice. Stores on ChatGPT, Claude and Cursor enable one‑click installs and Cloud already does dynamic connector discovery.
