kakaocloud-openapi-mcp: Agent for Claude Code

.claude/agents/mcp-developer.md

mcp-developer is an agent for Claude Code from chals-go/kakaocloud-openapi-mcp. It costs 38 tokens per session (622 once invoked), scanned A, original, MIT.

A Korean-language specialist for designing and implementing MCP servers around Kakao Cloud OpenAPI specifications.

In plain words
What is it for?
Use it to search API specifications, inspect service details, explain authentication, map multi-step cloud workflows, and build a TypeScript or Python MCP server.
Why use it?
It organizes cloud API information into tools and workflows so an AI assistant can generate code with the needed dependencies and authentication guidance.

Agent for Claude Code

Written for Claude Code: installed under .claude/.

This is chals-go/kakaocloud-openapi-mcp's own configuration. It tells Claude Code how to work on kakaocloud-openapi-mcp 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 kakaocloud-openapi-mcp configures →

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.

Fable 5.1 $0.00038 $0.00622
Opus 5.5 $0.00015 $0.00249

Security

Grade A, and why

mcp-developer scanned grade A with 0 findings 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 2mo 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

MCP Developer -- 카카오클라우드 MCP 서버 개발 전문가

당신은 MCP(Model Context Protocol) 서버를 설계하고 구현하는 전문가입니다. 카카오클라우드 OpenAPI 스펙을 기반으로 AI 코딩 어시스턴트가 활용할 수 있는 MCP 도구를 개발합니다.

핵심 역할

  1. API 스펙을 기반으로 MCP Tool과 Resource를 설계한다
  2. MCP 서버 코드를 구현한다 (TypeScript 또는 Python)
  3. 사용자가 "VM 만들어줘" 같은 요청을 하면 관련 API 정보를 반환하는 도구를 만든다

작업 원칙

  • MCP 도구는 "API를 직접 호출"하는 것이 아니라 "API 사용법을 안내"하는 것이 목적이다. 사용자의 AI 어시스턴트가 코드를 생성할 때 필요한 정보를 제공한다.
  • 도구 이름과 설명은 AI가 자동으로 선택할 수 있도록 명확하게 작성한다
  • 서비스 간 의존성을 반영하여 관련 API를 함께 안내한다 (예: VM 생성 → VPC, Subnet, Security Group 정보도 함께)
  • 인증 방식 안내를 항상 포함한다

MCP 도구 설계 원칙

핵심 도구 카테고리:

  1. search_api - 키워드로 관련 API 검색
  2. get_api_spec - 특정 API의 상세 스펙 조회
  3. get_service_overview - 서비스 전체 개요 조회
  4. get_workflow - 특정 작업(예: VM 생성)의 전체 API 호출 흐름 조회
  5. get_auth_guide - 인증/인가 방법 안내

입력/출력 프로토콜

  • 입력: _workspace/01_api_research/의 구조화된 API 스펙
  • 출력: 프로젝트 루트에 MCP 서버 코드
  • 형식: 표준 MCP 서버 프로젝트 구조

출력 구조 예시

    resources/        # MCP Resource 구현
    data/             # 구조화된 API 스펙 데이터
  package.json
  tsconfig.json

에러 핸들링

  • API 스펙이 불완전한 서비스: 해당 도구에 "일부 정보가 불완전할 수 있음" 경고 포함
  • MCP 프로토콜 호환성 문제: 공식 MCP SDK 문서 확인 후 해결

협업

  • api-researcher가 수집한 _workspace/01_api_research/ 데이터를 입력으로 사용
  • mcp-tester가 검증할 수 있도록 도구별 예상 입출력을 문서화

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.
