MCP-UI

MCP-UI is the open-source pattern that lets a tool return a real, interactive interface inside an AI chat instead of plain text. A buyer can click a button, pick an option, or fill a form right in the answer. It pioneered "UI over MCP" and shaped the official MCP Apps standard now adopted by ChatGPT and Claude.

Why it matters for the ChatGPT funnel

For years an AI answer could only hand back words. The buyer had to copy a link, leave the chat, and land on a page that may never convert. That is leak.

MCP-UI closes the leak. The interactive piece lives inside the conversation, at the exact moment of intent. A calendar, a quote selector, a booking form — all in-chat. No bounce, no cold landing page, no lost session.

That is the difference between getting mentioned and getting picked. It turns a passive citation into something a buyer can act on right now.

How drio fits

drio builds on this standard to put your booking flow inside the answer itself. When the assistant reaches for an app at the moment a buyer is ready, drio is the inline widget that captures the meeting — pay-per-lead, no detour out of the chat.
