qrcoding-connect

qrcoding-connect is a skill for Claude Code, Codex from contentscoin/qrcoding-skill-mcp. It costs 36 tokens per session (775 once invoked), scanned A, original, MIT.

A setup guide for connecting QR Agent Studio, a QR-code work platform, to Claude Code, Codex, or ChatGPT through MCP and skills.

In plain words
What is it for?
Use it to install the QR connection, configure authentication, restart the client, and add the service as a ChatGPT custom connector.
Why use it?
It explains the client-specific connection steps and how to handle API keys without exposing them.

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

qrcoding-connect 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 4d 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

QR Coding Connect

QR Agent Studio MCP/스킬을 사용 중인 AI 클라이언트에 연결한다. 연결만 다루며, 실제 QR 작업은 qrcoding-campaign-operator로 위임한다.

공통

  • Hosted MCP Gateway: https://qrcoding-skill-mcp.vercel.app/mcp
  • API key는 QR Agent Studio 대시보드의 Skills & MCP / Connect 패널에서 발급하며 qras_로 시작한다.
  • Claude Code·Codex: x-api-key 헤더 또는 QRCODING_API_KEY 환경변수로 인증한다. 키를 답변·로그·public URL에 노출하지 않는다.
  • ChatGPT: 헤더 인증을 지원하지 않으므로 키를 커스텀 커넥터 URL 경로(/mcp/<키>)에 넣고 No authentication으로 연결한다. 그 URL은 비밀번호처럼 취급한다(아래 ChatGPT 섹션).
  • 설치 스크립트는 내려받아 내용을 확인한 뒤 실행한다.
curl -fsSL https://raw.githubusercontent.com/contentscoin/qrcoding-skill-mcp/main/install.sh -o /tmp/qrcoding-install.sh
cat /tmp/qrcoding-install.sh

Claude Code

bash /tmp/qrcoding-install.sh --claude --mode=ops --skip-key

설치 후 Claude Code를 완전히 종료했다가 다시 시작한다. QRCODING_API_KEY를 환경에 설정한다.

Codex

bash /tmp/qrcoding-install.sh --codex --mode=ops --skip-key

설치 후 Codex를 재시작한다.

ChatGPT

유료 플랜 + 데스크톱 웹에서 커스텀 커넥터로 연결한다. OAuth/구글 로그인이나 별도 터널은 필요 없다.

  1. 대시보드 Connect 패널에서 키를 발급하고 ChatGPT용 커넥터 URL 전체를 복사한다. URL은 …/mcp/<발급키> 형태로 키가 경로에 포함된다.
  2. ChatGPT → 설정 → Connectors → Developer mode → Add custom connector.
  3. 복사한 URL을 붙여넣고 Authentication을 No authentication으로 선택한 뒤 Connect.
  4. 연결되면 새 대화에서 QR 생성·검증·수정을 자연어로 요청한다.

주의: 그 커넥터 URL은 키를 담고 있으므로 비밀번호처럼 다루고, 유출되면 대시보드에서 해당 키를 폐기한다. "Add custom connector"가 안 보이면 요금제·workspace 관리자 권한·데스크톱 웹 여부를 확인한다(모바일 미지원).

설치 구성

  • --mode=ops (기본): 운영 + 빠른시작 + 디자인 + 분석 + 연결 스킬.
  • --mode=dev: 연동 설계(integration-architect) + 연결 스킬.
  • --mode=full: 전체.

연결이 끝나면 "QR 만들어줘"는 qrcoding-quickstart, 분석은 qrcoding-analytics, 디자인은 qrcoding-designer가 받아 qrcoding-campaign-operator로 위임한다.

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.

qrcoding-connect is a skill published in the GitHub repository contentscoin/qrcoding-skill-mcp (0 stars, last pushed 2mo ago), licensed MIT. It adds 36 tokens to every session and 775 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
