설치

클라이언트 선택

~/Library/Application Support/Claude/claude_desktop_config.json · Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "korean-law": {
      "command": "npx",
      "args": [
        "-y",
        "korean-law-mcp"
      ],
      "_inferred": true
    }
  }
}

Claude Desktop → Settings → Developer → Edit Config 열기. 저장 후 앱 재시작.

~/.cursor/mcp.json · .cursor/mcp.json

{
  "mcpServers": {
    "korean-law": {
      "command": "npx",
      "args": [
        "-y",
        "korean-law-mcp"
      ],
      "_inferred": true
    }
  }
}

Cursor는 Claude Desktop과 동일한 mcpServers 스키마 사용. 프로젝트 설정이 전역보다 우선.

VS Code → Cline → MCP Servers → Edit

{
  "mcpServers": {
    "korean-law": {
      "command": "npx",
      "args": [
        "-y",
        "korean-law-mcp"
      ],
      "_inferred": true
    }
  }
}

Cline 사이드바의 MCP Servers 아이콘 클릭 후 "Edit Configuration" 선택.

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "korean-law": {
      "command": "npx",
      "args": [
        "-y",
        "korean-law-mcp"
      ],
      "_inferred": true
    }
  }
}

Claude Desktop과 같은 형식. Windsurf 재시작 후 적용.

~/.continue/config.json

{
  "mcpServers": [
    {
      "name": "korean-law",
      "command": "npx",
      "args": [
        "-y",
        "korean-law-mcp"
      ]
    }
  ]
}

Continue는 맵이 아닌 서버 오브젝트 배열 사용.

~/.config/zed/settings.json

{
  "context_servers": {
    "korean-law": {
      "command": {
        "path": "npx",
        "args": [
          "-y",
          "korean-law-mcp"
        ]
      }
    }
  }
}

context_servers에 추가. 저장 시 Zed가 핫 리로드.

비용 및 제한

운영 비용

API 쿼터: 법제처 public API has generous limits but no published SLA — be considerate
호출당 토큰: Statute texts: 2k-20k tokens; keep article-scoped queries
금액: Free — public API
팁: Use chain tools instead of manually stitching many execute_tool calls — faster + fewer tokens.

보안

권한, 시크릿, 파급범위

최소 스코프: None — public API

자격 증명 저장: No API key required

데이터 외부 송신: 법제처 Open API endpoints

절대 부여 금지: Nothing — read-only public data

This is a research assistant, not legal advice — all outputs need attorney review.

문제 해결

자주 발생하는 오류와 해결

Empty results for a common law

Try the official Korean name rather than English. search_law supports fuzzy Korean matching.

chain_* tool times out

Narrow the scope (single law or single year). Chain tools make many underlying calls.

Annexes return .hwp files that don't open

.hwp is Hangul Word Processor — install Hancom HWP viewer or convert via Hancom Docs.
