Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00038 | $0.00622 |
| Opus 5 | $0.00019 | $0.00311 |
| Sonnet 5 | $0.00008 | $0.00124 |
| Haiku 4.5 | $0.00004 | $0.00062 |
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 5d 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
- API 스펙을 기반으로 MCP Tool과 Resource를 설계한다
- MCP 서버 코드를 구현한다 (TypeScript 또는 Python)
- 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:
- search_api - 키워드로 관련 API 검색
- get_api_spec - 특정 API의 상세 스펙 조회
- get_service_overview - 서비스 전체 개요 조회
- get_workflow - 특정 작업(예: VM 생성)의 전체 API 호출 흐름 조회
- 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

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.
- 5d ago First seen · 60 lines · 38 tokens per session scan A f0beab42b2b7
mcp-developer is an agent published in the GitHub repository chals-go/kakaocloud-openapi-mcp (1 stars, last pushed 4mo ago), licensed MIT. It adds 38 tokens to every session and 622 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
