JSON MCP 서버(@gongrzhe/server-json-mcp@1.0.3)

JSON 데이터 쿼리 및 조작을 위한 JSON 모델 컨텍스트 프로토콜(MCP) 서버 구현입니다. 이 서버를 통해 LLM은 표준화된 도구 세트를 통해 JSON 데이터와 상호 작용할 수 있습니다.

설치 및 사용

구성 요소

도구

  • 질문

    • 확장된 작업을 사용하여 JSONPath 구문을 사용하여 JSON 데이터 쿼리

    • 입력:

      • url (문자열): JSON 데이터 소스의 URL

      • jsonPath (문자열): 선택적 작업이 포함된 JSONPath 표현식

  • 필터

    • 조건을 사용하여 JSON 데이터 필터링

    • 입력:

      • url (문자열): JSON 데이터 소스의 URL

      • jsonPath (문자열): 기본 JSONPath 표현식

      • condition (문자열): 필터 조건

지원되는 작업

배열 연산

  • 슬라이싱 : $[0:5] , $[-3:] , $[1:4]

  • 정렬 : $.sort(price) , $.sort(-price)

  • Distinct : $.distinct()

  • 변형 :

    • 맵: $.map(fieldName)

    • 평평하게 만들기: $.flatten()

    • 유니온: $.union([1,2,3])

    • 교차: $.intersection([1,2,3])

문자열 연산

  • 케이스 : $.toLowerCase() , $.toUpperCase()

  • 테스트 : $.startsWith('test') , $.endsWith('test')

  • 검색 : $.contains('test') , $.matches('pattern')

수치 연산

  • 수학 : $.math(+10) , $.pow2()

  • 반올림 : $.round() , $.floor() , $.ceil()

  • 함수 : $.abs() , $.sqrt()

날짜 작업

  • 형식 : $.format('YYYY-MM-DD')

  • 확인 : $.isToday()

  • 수정 : $.add(1, 'days')

집계 작업

  • 그룹 : $.groupBy(category)

  • 통계 : $.sum(price) , $.avg(price) , $.min(price) , $.max(price)

구성

Claude Desktop과 함께 사용

Claude Desktop 앱과 함께 이 서버를 사용하려면 claude_desktop_config.json 에 다음 구성을 추가하세요.

{
  "json": {
    "command": "npx",
    "args": [
      "@gongrzhe/server-json-mcp@1.0.3"
    ]
  }
}

또는 패키지가 설치되어 있다면 node 명령을 직접 사용할 수 있습니다.

{
  "json": {
    "command": "node",
    "args": [
      "path/to/build/index.js"
    ]
  }
}

개발

소스에서 빌드

  1. 저장소를 복제합니다

  2. 종속성 설치:

    npm install

  3. 프로젝트를 빌드하세요:

    npm run build

노트

  1. 모든 JSONPath 표현식은 루트 객체를 나타내는 $ 로 시작합니다.

  2. 배열 인덱스는 0부터 시작합니다.

  3. 연산의 문자열 값은 따옴표로 묶어야 합니다.

  4. 날짜 연산은 '일', '월', '년' 단위를 지원합니다.

  5. 숫자 연산은 기본 산술 연산자(+, -, *, /)를 지원합니다.

    C2.8/5.0

    Scored across 2 tools

    Disambiguation3/5

    The tools 'filter' and 'query' both operate on JSON data, which creates some overlap in purpose, as filtering can be seen as a subset of querying. However, the descriptions differentiate them: 'filter' uses conditions (likely simpler, boolean-based operations), while 'query' uses JSONPath syntax (a more expressive, path-based language). This distinction helps reduce confusion, but an agent might still struggle to choose between them for certain tasks.

    Naming Consistency5/5

    Both tool names follow a consistent pattern: they are single, lowercase verbs ('filter' and 'query') that clearly indicate actions. There are no deviations in style (e.g., no mixing with snake_case or camelCase), making the naming predictable and easy to understand across the set.

    Tool Count2/5

    With only 2 tools, this server feels thin for a JSON processing domain, which typically involves operations like parsing, transforming, validating, or merging JSON. The limited scope may force agents to work around gaps, as basic tasks like reading or writing JSON files are not covered, making it under-scoped for a general-purpose JSON server.

    Completeness2/5

    The tool set is severely incomplete for JSON processing. While 'filter' and 'query' handle retrieval and selection, there are no tools for creating, updating, validating, or manipulating JSON structures (e.g., add, remove, merge). This leaves significant gaps that will likely cause agent failures when trying to perform common JSON operations beyond simple queries.
