Show HN: AINativeKit-UI – Turn MCP JSON into ChatGPT App UIs (opens in new tab)

I've been working with the new ChatGPT Apps SDK from OpenAI and found that turning MCP JSON results into usable UI takes a lot of repetitive React work.

So I built AINativeKit-UI, an open-source React component library that:

- Instantly maps structured MCP JSON -> UI

- Works directly with the ChatGPT Apps SDK

- Adapts beautifully to mobile and desktop ChatGPT interfaces

- Follows OpenAI’s Figma-aligned design system for consistency

- Includes prebuilt Cards, Lists, Maps, and Carousels

- Is fully TypeScript, accessible, and MIT licensed

Demo: ainativekit.com

Code: github.com/AINativeKit/ainativekit-ui

The goal is to help developers focus on AI logic instead of UI wiring.

Would love your thoughts on:

- What components or patterns should come next?

- How could this integrate better with your ChatGPT App workflow?
