npx @nitrostack/cli init my-server
cd my-server && npm install && npm run dev
npm i @nitrostack/core (framework), npm i -g @nitrostack/cli (scaffolding), npm i @nitrostack/widgets (React UI SDK)

Usage

• •Prerequisites: Node.js >= 20.18 and npm >= 9
• •Define tools with @Tool decorators plus Zod inputSchema; add @UseGuards, @Cache, @Widget decorators for auth, caching, and UI
• •Open the scaffolded project in NitroStudio desktop app for visual testing, payload inspection, and built-in AI chat
• •Connect the running server to any MCP-compatible client

Key features

• ✓Decorator-driven tools, resources, and prompts; first-class DI container (singleton/transient/scoped)
• ✓Built-in auth: JWT, OAuth 2.1, API key; middleware pipeline with guards, interceptors, pipes, exception filters
• ✓UI Widgets attach React components to tool outputs for interactive responses; Zod end-to-end type safety
• ✓NitroStudio desktop app for testing/debugging/chatting with the server; hot reload
• ✓Doctored for deployment: production checklist, Docker, cloud platforms

Best for

Teams building production MCP servers in TypeScript with enterprise patterns (auth, DI, middleware, UI) out of the box.

Caveats

• ⚠Framework, not a ready-to-run MCP server; no server is shipped
• ⚠Requires Node.js >= 20.18 and npm >= 9
