Provides a full‑stack TypeScript framework for building, testing, and deploying production‑ready MCP servers and AI‑native applications.
NitroStack offers an opinionated, batteries‑included framework that lets developers create enterprise‑grade MCP servers with minimal boilerplate. It combines decorator‑driven definitions, dependency injection, built‑in authentication, middleware pipelines, and UI widget integration into a single cohesive stack.
npx @nitrostack/cli init my-server.cd my-server && npm install.npm run dev. The server starts locally and can be accessed by any MCP‑compatible client.@nitrostack/core, @nitrostack/cli, @nitrostack/widgets).Q: Do I need to know MCP to use NitroStack? A: No. NitroStack abstracts protocol details; you focus on defining tools and business logic.
Q: Can I use NitroStack with existing Node.js projects?
A: Yes. You can add @nitrostack/core to any TypeScript project and register modules manually.
Q: How is deployment handled?
A: Use the standard Node.js deployment workflow – Docker, cloud platforms, or serverless – after building the project (npm run build).
Q: What IDE support is available? A: Full TypeScript typings, plus NitroStudio for visual debugging and widget preview.
Q: Where can I get help? A: Join the Discord community, GitHub discussions, or consult the official documentation at https://docs.nitrostack.ai.

npx @nitrostack/cli init my-server

cd my-server
npm install
npm run dev
Your MCP server is running. Connect it to any MCP-compatible client.
Once your project is scaffolded, open the same folder in NitroStudio for visual testing and debugging.
my-server project folderBuilding MCP servers today means stitching together boilerplate, reinventing authentication, and hoping your tooling scales. NitroStack gives you an opinionated, batteries-included framework so you can focus on what your server actually does.
import { McpApp, Module, ToolDecorator as Tool, z, ExecutionContext } from '@nitrostack/core';
@McpApp({
module: AppModule,
server: { name: 'my-server', version: '1.0.0' }
})
@Module({ imports: [] })
export class AppModule {}
export class SearchTools {
@Tool({
name: 'search_products',
description: 'Search the product catalog',
inputSchema: z.object({
query: z.string().describe('Search query'),
maxResults: z.number().default(10)
})
})
@UseGuards(ApiKeyGuard)
@Cache({ ttl: 300 })
@Widget('product-grid')
async search(input: { query: string; maxResults: number }, ctx: ExecutionContext) {
ctx.logger.info('Searching products', { query: input.query });
return this.productService.search(input.query, input.maxResults);
}
}
One decorator stack gives you: API definition + validation + auth + caching + UI — zero boilerplate.
NitroStack is modular. Install only what you need:
The implementation workspace for NitroStack packages lives in typescript/.
| Package | What it does | Install |
|---|---|---|
@nitrostack/core |
The framework — decorators, DI, server runtime | npm i @nitrostack/core |
@nitrostack/cli |
Scaffolding, dev server, code generators | npm i -g @nitrostack/cli |
@nitrostack/widgets |
React SDK for interactive tool output UIs | npm i @nitrostack/widgets |
NitroStudio is a desktop app purpose-built for developing MCP servers. Open your project folder — it handles the dev server for you.

Real-time tool testing Execute tools, inspect payloads, and debug request/response cycles.

Built-in AI chat Talk to your MCP server through an integrated AI assistant.
