You should use the new MCP UI option in ChatGPT and Claude not because it looks good, but because it can provide missing logic.
For example:
- You can implement an upload component, which is super useful because MCP can't upload files.
- You can implement a poller - usually the client side of ChatGPT and claude, won't pull for a video status if you generate something; a UI widget can solve it.
Thank me later :)
