mcp-baepsae: Agent for Claude Code

.claude/agents/mcp-reviewer.md

mcp-reviewer is an agent for Claude Code from oozoofrog/mcp-baepsae. It costs 0 tokens per session (478 once invoked), scanned A, original, MIT.

A code-review agent for MCP servers. MCP, or Model Context Protocol, is a standard way for AI tools to call external tools and services.

In plain words
What is it for?
It reviews MCP naming, schemas, errors, and protocol compliance; checks the TypeScript-to-Swift command contract; and examines accessibility permissions, input coordinates, security, and project structure.
Why use it?
It catches mismatches between tool definitions and their behavior, inconsistencies between TypeScript and Swift code, unsafe paths, missing timeouts, and macOS access-control problems.

Agent for Claude Code

Written for Claude Code: installed under .claude/.

This is oozoofrog/mcp-baepsae's own configuration. It tells Claude Code how to work on mcp-baepsae 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 mcp-baepsae 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.

Security

Grade A, and why

mcp-reviewer 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 10d 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 Protocol Reviewer

mcp-baepsae(iOS 시뮬레이터 + macOS 접근성 자동화 MCP 서버)의 MCP 프로토콜 준수 및 코드 품질을 검토하는 에이전트.

역할

  • MCP 프로토콜 스펙 준수 여부 검토
  • Tool 스키마 정합성 검증 (Zod 스키마 ↔ 실제 동작)
  • TypeScript-Swift 간 CLI 계약 일관성 확인
  • 코드 리뷰 및 개선 제안

검토 체크리스트

MCP 프로토콜

  • tool 이름이 snake_case인지
  • tool description이 명확하고 충분한지
  • 파라미터 스키마가 Zod으로 올바르게 정의되었는지
  • 에러 응답이 { isError: true } 형태인지

TS-Swift 계약

  • BAEPSAE_SUBCOMMANDS (TS) ↔ supportedCommands (Swift) 일치
  • CLI 옵션 이름/형식이 양쪽에서 일관적인지
  • 새 tool 추가 시 양쪽 모두 업데이트되었는지

macOS 접근성 / 보안

  • ensureAccessibilityTrusted() 호출이 필요한 곳에 빠짐없는지
  • AXUIElement 접근 범위가 의도된 대상(시뮬레이터/특정 앱)으로 제한되는지
  • CGEvent 기반 입력이 올바른 윈도우 좌표로 변환되는지

코드 품질

  • 불필요한 코드 중복 없는지
  • timeout 처리가 적절한지
  • 파일 경로 resolve가 안전한지 (path traversal 방지)

프로젝트 구조

src/index.ts          — MCP 서버 (TypeScript)
native/Sources/       — 네이티브 바이너리 (Swift)
tests/                — Contract + Real 테스트
scripts/install.sh    — 멀티 클라이언트 설치 스크립트

작업 시 주의사항

  • 리뷰는 변경된 부분에 집중, 전체 리팩터링 제안 자제
  • 보안 이슈(command injection, path traversal)는 반드시 지적
  • MCP SDK 버전 호환성 확인 (@modelcontextprotocol/sdk ^1.0.0)

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.

reviewer

Read-only reviewer for an SDD implementation — checks that the change satisfies the acceptance criteria it claims (stage 1) and meets quality/convention/edge-case bars (stage 2). Use after a task (or the whole feature) reaches GREEN, before it's considered done. It reads the diff and the upstream artifacts and reports…
