@nitrostack/core

TypeScript framework for building production-ready MCP servers with decorators, dependency injection, validation, auth, and middleware pipelines.

Installation

npm install @nitrostack/core zod reflect-metadata

Why @nitrostack/core

• Decorator-first authoring for tools, resources, and prompts
• Built-in DI container with module architecture
• Auth primitives for API key, JWT, and OAuth 2.1 flows
• Middleware-style request lifecycle (guards, pipes, interceptors)
• Strong runtime validation with Zod-based schemas

Quick Example

import { McpApp, Module, ToolDecorator as Tool, z } from '@nitrostack/core';

export class MathTools {
  @Tool({
    name: 'add_numbers',
    description: 'Add two numbers',
    inputSchema: z.object({
      a: z.number(),
      b: z.number(),
    }),
  })
  async add(input: { a: number; b: number }) {
    return { result: input.a + input.b };
  }
}

@McpApp({
  server: { name: 'math-server', version: '1.0.0' },
})
@Module({
  name: 'app',
  controllers: [MathTools],
})
export class AppModule {}
