Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@mcp-qrgenerate a QR code for https://example.com"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
mcp-qr
텍스트/URL을 QR 코드 PNG로 생성해 반환하는 MCP 서버. Hermes에 "이거 QR로 보여줘"라고 하면 이미지를 돌려준다.
이 repo는 QR MCP인 동시에, 이후 Node 계열 MCP가 복사해 쓰는 레퍼런스 구조다. (표준:
00_MCP_표준_아키텍처_v1)
도구
generate_qr
QR 코드를 PNG로 생성한다.
파라미터 | 타입 | 필수 | 기본 | 설명 |
| string | ✅ | — | 인코딩할 텍스트/URL |
|
|
| 오류 정정 수준 | |
| number(px) |
| 출력 한 변 길이 (64–2048) | |
| number |
| 여백(모듈 단위, 0–20) | |
| string(hex) |
| 전경색 | |
| string(hex) |
| 배경색 |
출력: PNG image 콘텐츠 + 구조화 텍스트(인코딩한 원문, 적용된 옵션 요약).
예제 출력: examples/qr_example.png (https://zeolinex.com, 기본 옵션).

설치
git clone https://github.com/molpass/mcp-qr.git
cd mcp-qr
npm install && npm run build예제 PNG를 직접 생성해 보려면:
npm run example # examples/qr_example.png 재생성Hermes / MCP 등록
MCP 클라이언트 설정(JSON)에 등록한다. 서버명은 qr:
{
"mcpServers": {
"qr": {
"command": "node",
"args": ["/abs/path/mcp-qr/dist/index.js"]
}
}
}
/abs/path는 클론한 실제 절대경로로 바꾼다. Windows 예:"args": ["C:/Users/<you>/mcp-qr/dist/index.js"]기존 등록 MCP(korean-law-mcp 등)와 동일한 방식.
스택
Node 20+ / TypeScript
@modelcontextprotocol/sdk(stdio)qrcode(PNG 생성)
로고 합성·라운드 스타일 등 후처리(sharp 기반)는 v1.1로 분리한다. v1은 색상/크기/여백/정정수준 조합까지.
