af-jupyterlab-mcp

AF 사용자가 UChicago ATLAS Analysis Facility Kubernetes 클러스터에서 자신의 사용자별 JupyterLab 서버를 생성, 검사, 삭제할 수 있게 해주는 MCP 서버입니다. 현재 af-portal이 배포하는 것과 동일한 노트북을 LLM용 도구로 노출합니다.

아키텍처

LLM <--MCP/HTTP--> af-jupyterlab-mcp <--k8s API--> notebook namespace (Pod/Service/Secret/Ingress)
                         ^
                         | Authorization: Bearer <broker-issued JWT>
                         |
              af-mcp-platform credential broker

1단계(현재 이 저장소)는 af-portal의 portal/jupyterlab.py와 네 개의 Jinja 템플릿에서 포팅한, 노트북의 Pod/Service/Secret/Ingress 4중 항목을 관리하는 여섯 가지 도구를 제공합니다. 2단계(추적 중, 아직 구축되지 않음)는 노트북 내부에서 실행되는 Datalayer jupyter-mcp-server에 대한 타입 프록시를 추가합니다 — maniaclab/af-mcp-platform#189 참조.
