My Little MCP Server

현재 시간과 랜덤 숫자를 제공하는 아주 간단한 MCP (Model Context Protocol) 서버입니다.

기능

  1. 현재 시간 조회 (get_current_time)

    • 한국 시간(KST) 기준으로 현재 날짜와 시간을 반환

    • 포맷: locale (기본), iso, timestamp

  2. 랜덤 숫자 생성 (get_random_number)

    • 1~50 사이의 랜덤한 숫자를 생성

    • 범위 커스터마이징 가능 (1~100)

설치 및 실행

# 의존성 설치
npm install

# 빌드
npm run build

stdio transport (기본)

# 개발 모드
npm run dev

# 프로덕션
npm start

HTTP transport

# 개발 모드 (포트 8004)
npm run dev:http

# 프로덕션 (포트 8004)
npm run start:http

# 커스텀 포트
npm run dev -- --transport=http --port=8005

사용법

MCP 클라이언트에서 사용

Cursor (.cursor/mcp.json)

{
  "mcpServers": {
    "my-little-mcp": {
      "command": "node",
      "args": ["/Users/swan/swan/chequer-projects/chequer-io/ironman/mcp-suite/mcp-servers/my-little-mcp/dist/index.js"]
    }
  }
}

Claude Desktop (claude_desktop_config.json)

{
  "mcpServers": {
    "my-little-mcp": {
      "command": "node", 
      "args": ["/Users/swan/swan/chequer-projects/chequer-io/ironman/mcp-suite/mcp-servers/my-little-mcp/dist/index.js"]
    }
  }
}

HTTP transport 사용 시

Cursor (.cursor/mcp.json):

{
  "mcpServers": {
    "my-little-mcp": {
      "url": "http://localhost:8004/mcp"
    }
  }
}

로컬에서 테스트

stdio transport

# MCP Inspector로 테스트
npx @modelcontextprotocol/inspector node dist/index.js

HTTP transport

# 서버 실행 (별도 터미널)
npm run start:http

# MCP Inspector로 테스트
npx @modelcontextprotocol/inspector http://localhost:8004/mcp

# 또는 직접 HTTP API 호출
curl http://localhost:8004/health
curl http://localhost:8004/

도구 사용 예제

현재 시간 조회

  • 기본: get_current_time

  • ISO 포맷: get_current_time with {"format": "iso"}

  • 타임스탬프: get_current_time with {"format": "timestamp"}

랜덤 숫자 생성

  • 기본 (1-50): get_random_number

  • 커스텀 범위: get_random_number with {"min": 10, "max": 30}

특징

  • 매우 간단함: 100줄 미만의 코드

  • 순수 MCP SDK: 추가 의존성 최소화

  • 한국어 지원: 한국 시간대 및 한국어 메시지

  • 타입 안전성: TypeScript + Zod

요구사항

  • Node.js 18.0.0+

  • TypeScript 5.0+

    TDQS

    A3.5/5.0

    Scored across 2 tools

    Disambiguation5/5

    The two tools have completely distinct purposes: one returns the current time in KST, and the other generates a random number between 1 and 50. There is no overlap in functionality, making it impossible to confuse them.

    Naming Consistency5/5

    Both tools follow a consistent verb_noun naming pattern (get_current_time and get_random_number), using snake_case and starting with 'get_' to indicate retrieval actions. This uniformity makes the set predictable and easy to understand.

    Tool Count2/5

    With only two tools, the server feels thin and under-scoped for any meaningful domain, such as time or random number utilities. It lacks depth, offering basic functions without supporting operations like time conversion or number range adjustments.

    Completeness2/5

    Inferred as a utility server, the toolset is severely incomplete. For time-related functions, there are no tools for timezone conversion or formatting, and for random numbers, no tools to set custom ranges or generate sequences. This leaves obvious gaps in coverage.
