Show HN: Sunpeak – open-source MCP App SDK

I tried building a ChatGPT App using the new OpenAI UI components and example code, but I found myself writing more platform & testing boilerplate than application code.

I built sunpeak so we can skip the boilerplate and get straight to building our ChatGPT (and future Gemini, Claude, etc.) Apps!

Would be extremely grateful for a star and some feedback!
