문제
노드 버전 하나로 정리 + 인텔리제이 2025 버전으로 업그레이드
+ 인텔리제이 전 버전 삭제했으나 폴더 남아있어서 다 삭제
그럼에도 2분 후 타임아웃이 자꾸 발생했다....
처음에 클로드 접속할 땐 괜찮았는데, 조금 있다가 자꾸 연결이 끊어지니까 토큰 문제인가 싶기도 했다.
근데 별로 안 썼는데... (진짠데...)
로그는 아래와 같다.

해결 시도
세션 타임아웃이 발생하는 이유:
- MCP 클라이언트 타임아웃 설정
- Claude 클라이언트가 약 1분(60초) 후에 "McpError: MCP error -32001: Request timed out" 에러를 발생시키고 있습니다
- 이는 Claude 측의 하드코딩된 타임아웃 설정으로 보입니다
- IntelliJ MCP 서버의 세션 관리 문제
- 세션이 끊어진 후 "Session not found" 404 에러가 발생
- IntelliJ MCP 서버가 세션을 적절히 유지하지 못하고 있음
- 프로토콜 버전 불일치
- Claude가 요청하는 프로토콜: "2025-06-18"
- IntelliJ가 응답하는 프로토콜: "2024-11-05"
- 버전 차이로 인한 호환성 문제 가능성
구체적인 문제점:
- 14:53:42: 연결 성공
- 14:54:42: 정확히 1분 후 타임아웃 발생
- 14:54:46: 세션이 이미 종료되어 404 에러 발생
이것도 체크해서 지웠더니
이번엔 전보다 조금 더 많이 작동된다!
근데 5분뒤에 다시 failed로 바뀌었다.
이번에 생긴 로그는 조금 다르길래, 분석해봤더니
연결 상태: 정상
초기 연결 성공
- 2025-09-03T15:08:18: 서버 시작 및 연결 성공
- MCP 프로토콜 handshake 완료 (initialize → initialized)
- IntelliJ IDEA MCP Server 2025.2.1과 정상 통신
도구 등록 완료
- 모든 JetBrains 도구들이 정상적으로 로드됨 (총 20개 도구)
- 파일 조작, 검색, 실행, 리팩토링 등 모든 기능 사용 가능
실제 작업 수행 기록
- 15:08:39~15:09:13: 약 5분간 지속적인 파일 작업
- 디렉토리 탐색, 파일 검색, 코드 읽기 등 14개 요청 성공
- Spring Boot 프로젝트의 Place/UserPlace 관련 코드 분석 완료
문제점: 일시적 타임아웃
타임아웃 발생
- 15:09:18: "Request timed out" 오류로 연결 끊김
- 15:13:21: 4분 후 다시 타임아웃 발생
원인 추정
- 대용량 파일 읽기 시도 (PlaceService.java)
- IDE 과부하 또는 일시적 응답 지연
- 네트워크나 프로세스 간 통신 지연
결론
연결 자체는 정상이며, 대부분의 기능이 잘 작동합니다. 간헐적 타임아웃은 IDE나 시스템 리소스 문제로 보이며, 재연결하면 다시 정상 작동할 것으로 예상됩니다.
라고한다.
잘 되는지 테스트해보려고 몇 번 시도한 게 다인데
......
클로드 pro 사용 이대로 괜찮을까?...
결론
생각보다 pro 토큰이 너무 적다. 다른 방법을 찾아봐야할듯...
클로드 code를 이용하면 어떨지 봐야겠다!
