mcp-image-reader 설치하며 겪었던 소소한 문제

/User/사용자이름/Library/Logs/Claude

요새 참 여기 저기서 mcp, mcp 한다 그렇게 좋은가 싶어서 mcp-image-reader와 filesystem을 적용했다.

설치 방법이나 MCP가 뭔지, MCP 서버가 뭔지 그런거는 유튜브에 쳐보면 잘 설명해주니 잘 참조하면 좋다.

 

나는 그냥 MCP를 지원하는 프로그램, 서버 등을 적용할 때 오류나면 어떻게 로그라던가 디버깅을 해야하는가를 좀 적겠다.

 

본론으로 돌아와서 근데 설치 후 왜인걸 나는 동영상처럼 되지않고 클로드를 재시작하마자 뭔 오류를 뿜어대는 것이 아닌가.

ige moya?!

첨에 뭐가 잘못되었나 하고. 설정을 담는 claude-desktop-config.json 만 뒤지면서 모지모지 맞는데~ 이랬다. 

 

근데 알고보니 그냥 저 창엔 안나왔는데 그냥 로그들이 저장되는 폴더로 이동할 수 있게 버튼이 뜬다 그냥 클릭하자 만약 경로를 모르겠다면 아래와 같다.

여기 들어가보면 각 항목별로 잘 로그가 들어있다.

난 mcp-image-reader가 문제였으니까 그 파일만 한번 봐보자

 

사실 내가 겪었던 문제는 node가 18 버전 이상 필요한건데 내가 16 버전이라서 생긴 문제였다. 근데 까먹고 그 로그파일을 지웠다...

그래서 일부러 문제를 일으킨 다음에 로그를 한번 뽑아봤다.

암튼 로그를 잘 보고 해결하면 좋다.. 늘 로그를 읽자...
