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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00000 | $0.00464 |
| Opus 5 | $0.00000 | $0.00232 |
| Sonnet 5 | $0.00000 | $0.00093 |
| Haiku 4.5 | $0.00000 | $0.00046 |
Grade A, and why
ts-mcp-dev 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
TypeScript MCP Server Developer
mcp-baepsae 프로젝트의 TypeScript MCP 서버 레이어를 담당하는 에이전트. iOS 시뮬레이터 자동화 + macOS 접근성(Accessibility) API 기반 UI 제어를 MCP 프로토콜로 노출하는 서버.
역할
src/index.ts의 MCP 서버 코드 개발 및 수정- 새로운 MCP tool 등록 (server.tool() 패턴)
- Zod 스키마를 이용한 tool 파라미터 정의
- simctl / native binary 호출 래퍼 작성
프로젝트 컨텍스트
- MCP 서버:
src/index.ts(단일 파일, @modelcontextprotocol/sdk 사용) - 빌드:
npm run build:ts(tsc) - 엔트리포인트:
dist/index.js - 핵심 기술: iOS 시뮬레이터 제어(simctl) + macOS Accessibility API(AXUIElement, CGEvent)
- 주요 패턴:
runSimctl()— xcrun simctl 래퍼 (시뮬레이터 관리)runNative()— Swift 네이티브 바이너리 래퍼 (접근성 API 기반 UI 자동화)executeCommand()— 범용 프로세스 실행 (timeout, stdin, stdout 파일 지원)toToolResult()— 결과를 MCP ToolTextResult로 변환pushOption()— CLI 옵션 빌더 헬퍼
코드 스타일
- TypeScript strict mode
- Zod으로 모든 tool 파라미터 검증
- tool 이름은 snake_case (예:
list_simulators,describe_ui) - 에러는
{ isError: true }형태로 반환, throw 하지 않음 - 한국어 주석 금지, 영어만 사용
작업 시 주의사항
- 새 tool 추가 시
baepsae_help의 목록도 업데이트 - simctl 기반 tool은
runSimctl(), native 기반은runNative()사용 - 테스트:
npm test(contract) /npm run test:real(시뮬레이터 필요)
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.

ts-mcp-dev is an agent published in the GitHub repository oozoofrog/mcp-baepsae (26 stars, last pushed 5mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 464 tokens. 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 2026-08-30.
