--- schema: 1 type: video title: 'MCP UI: Extending the frontier — Liad Yosef and Ido Salomon, MCP Apps' description: >- Chat interfaces are no longer limited to walls of text. In this talk, Liad Yosef and Ido Salomon explain how MCP Apps turn tools into interactive UI inside hosts like ChatGPT, Claude, VS Code, Cursor, and Copilot, letting companies send branded, functional app experiences instead of plain text responses. The session covers the core architecture behind MCP Apps, how UI is passed over MCP, how interactions stay in context through the host, and why this changes how applications get distributed in an agent-first world. If you're building on MCP, this is a practical look at the emerging standard for UI inside chat.
