Create Sunpeak App

Sunpeak is a React framework built on @modelcontextprotocol/ext-apps for building MCP Apps with interactive UIs that run inside AI chat hosts (ChatGPT, Claude). It provides React hooks, a dev inspector, a CLI (sunpeak dev / sunpeak build / sunpeak start), and a structured project convention.

Getting Reference Code

Clone the sunpeak repo for working examples:

git clone --depth 1 https://github.com/Sunpeak-AI/sunpeak /tmp/sunpeak

Use when testing MCP servers -- e2e tests with the sunpeak inspector, visual regression testing, live testing against real ChatGPT, multi-model evals, Playwright configuration, or scaffolding test infrastructure with "sunpeak test init". Works with any MCP server (Python, Go, TypeScript, etc.), not just sunpeak projects.
