# sunpeak
Server-agnostic MCP testing framework and full-stack MCP App framework.
MCP Apps are cross-platform, meaning sunpeak is a ChatGPT App framework, Claude Connector framework, and more.
Current releases use MCP Apps SDK 2.0 and the split MCP TypeScript client, server, core, and Node packages. Projects that read tool handler context directly should use `extra.mcpReq` for request data and `extra.http?.authInfo` for validated HTTP auth.
ChatGPT apps are now submitted and published as plugins. The app remains an MCP-backed app, so sunpeak's architecture and runtime do not change. The plugin is the package used for local installation, review, and public distribution.
```bash
npx sunpeak new
