.claude/commands/add-mcp-server.md

add-mcp-server is a command for Claude Code from Koomook/data-go-mcp-servers. It costs 14 tokens per session (2,031 once invoked), scanned A, original, Apache-2.0.

A command that creates an MCP server for South Korea’s data.go.kr API, a government data service, from its API documentation. MCP is a standard way for AI tools to use external services.

In plain words
What is it for?
Use it to provide API endpoints, authentication details, request fields, response formats, and error codes when creating a new data.go.kr MCP server.
Why use it?
It organizes the information needed to turn an API description into an automated server setup.

Command for Claude Code

Written for Claude Code: argument-hint in frontmatter.

This is Koomook/data-go-mcp-servers's own configuration. It tells Claude Code how to work on data-go-mcp-servers itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything data-go-mcp-servers configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is uv run python scripts/deploy_to_pypi.py {api-name}.

Reuse

Borrowing it

Nothing to install: this file belongs to Koomook/data-go-mcp-servers. Take a copy, put it at the same path in your own repository, and replace the rules that are about this project with yours.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

add-mcp-server scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

🚀 Create New MCP Server for data.go.kr API

I'll help you create a new MCP server. Please paste the API documentation, and I'll extract all necessary information and guide you through the implementation.

📋 Required Input

1. API Documentation (paste everything)

Please provide comprehensive API documentation that includes:

Essential Information:
  • API 서비스명 (Korean/English name)

    • API key parameter name (e.g., serviceKey, ServiceKey, apiKey)
    • Where it goes: URL parameter or header?
    • Response format: JSON or XML (default: JSON)
Endpoint Details (for each endpoint):
  • HTTP Method: GET or POST
  • Endpoint path: /validate, /status, /search etc.
  • Request parameters:
    • Required fields with types
    • Optional fields with defaults
    • Field constraints (max length, format, etc.)
    • Korean field names and descriptions
  • Request body format (for POST):
    • JSON structure
    • Array or single object
    • Max items per request (e.g., 100 items)
  • Response structure:
    • Success response format
    • Error response format
    • Status codes and meanings
    • Data field names and types
API Constraints:
  • Rate limits (requests per second/minute)
  • Max items per request
  • Pagination support (page, perPage, etc.)
  • Special requirements (date formats, encoding, etc.)

2. Usage Examples (필수)

Provide 2-3 concrete examples of how this API will be used:

Example 1: "사업자등록번호 123-45-67890이 2020년 1월 1일에 홍길동 대표로 개업한 것이 맞는지 확인해줘"
Expected: validate_business tool validates the business registration

Example 2: "서울시 강남구의 실시간 대기질 정보를 알려줘"
Expected: get_air_quality tool returns PM10, PM2.5 levels

Example 3: "부산에서 서울로 가는 KTX 시간표 조회"
Expected: search_train_schedule tool returns departure times and availability

3. Sample API Request/Response (실제 데이터)

Include actual API call examples:

// Request
POST https://api.example.kr/v1/validate
{
  "businesses": [{
    "b_no": "1234567890",
    "start_dt": "20200101",
    "p_nm": "홍길동"
  }]
}

// Response
{
  "status_code": "OK",
  "data": [{
    "b_no": "1234567890",
    "valid": "01",
    "valid_msg": "일치"
  }]
}

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
