Project instructions for schoolinfo-mcp, a service that provides school information through a web app and an MCP connection. They describe its separate Vercel web deployment and Fly-hosted MCP deployment.

In plain words
What is it for?
Use them when changing, building, deploying, or troubleshooting the schoolinfo-mcp project. They also describe how to verify the production health endpoint.
Why use it?
They document deployment details, environment variables, URL routing, performance limits, and regional school-code handling. This reduces the risk of deploying the wrong entry point or breaking school lookups.

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

schoolinfo-mcp CLAUDE.md 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.

What it actually says

CLAUDE.md

⚠️ 배포 — 두 갈래 (MCP는 fly 통합호스트, 웹앱은 Vercel)

웹앱 — Vercel school.gomdori.app (2026-07-04부터)

공식 웹앱(브라우저용 UI + /api/* + /mcp)은 **Vercel 프로젝트 schoolinfo-mcp**로 서빙. 주소 https://school.gomdori.app.

  • 함정: 이 패키지는 npm 라이브러리(main: ./dist/index.js)를 겸해서, Vercel 기본 감지(framework: node)가 라이브러리 진입점을 서버 함수로 오인 → FUNCTION_INVOCATION_FAILED("Invalid export"). 그래서 vercel.jsonframework: null + functions."api/index.ts" 단일 함수로 고정하고, 전 경로를 rewrites/api/index?__vpath=/$1에 실어 보낸 뒤 api/index.ts에서 원경로 복원(고정 destination rewrite는 req.url을 덮어씀).
  • 반영 절차: main 커밋·푸시 후 cd ~/workspace/schoolinfo-mcp && vercel build --prod && vercel deploy --prebuilt --prod (클라우드 빌드는 감지 이슈로 불안정 → 로컬 빌드 후 --prebuilt 업로드가 정석) → curl https://school.gomdori.app/health 확인
  • env: SCHOOLINFO_API_KEY·NEIS_API_KEY가 Vercel 프로젝트(production/preview)에 등록돼 있음
  • 파싱 성능 주의: 큰 수행평가 hwpx(1.6MB)가 서버리스에서 13~18초(로컬 1.2초). memory 상향은 무효 확인 → 병목은 학교알리미 다운로드(외부). maxDuration 60(기본 300s)라 타임아웃은 안 남
  • 지역코드: src/regions.json은 2026 개편(전남광주통합특별시·인천 신설구·화성 분구)을 union으로 반영 — 학교알리미 API가 과도기라 구(광주광역시/전라남도)·신(전남광주통합특별시) 명칭을 섞어 주므로 both 유지해야 브릿지가 안 깨짐

MCP — fly 통합 호스트 (2026-07-02부터)

MCP 전용 서빙은 gomdori-mcp 통합 호스트(fly 앱 korean-law-mcp 1대, MCP 5종 동거).

  • MCP 주소: https://mcp.gomdori.app/school (MCP 엔드포인트. /school/xyz는 프리픽스만 벗겨 전달)
  • 구 fly 앱 school-mcp중단 상태(fly scale count 0, 주소·앱은 보존) — 복구는 fly scale count 1 -a school-mcp
  • 반영 절차: main에 커밋·푸시한 뒤 cd ~/workspace/gomdori-mcp && fly deploy -c fly.production.toml (Dockerfile이 GitHub main을 clone→tsup 빌드) → curl https://mcp.gomdori.app/healthz 확인
  • 시크릿 SCHOOLINFO_API_KEY·NEIS_API_KEY는 korean-law-mcp 앱에도 이관돼 있음
Changes

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.
