Four live demos adding interactive Views to a production MCP server using ext-apps. Demo 1: side-by-side translation diff with glossary term highlighting and model quality comparison. Demo 2: D3 force-directed network graph exploring 10k+ glossary terms across 30 languages. Demo 3: inline glossary marketplace – browse, preview, one-click install. Demo 4: drop a product photo, Gemini OCR extracts text, DeepL translates it, Imagen 3 regenerates the image with culturally adapted people and scenery. All rendering inline in the chat, all calling back to the server from the iframe.
