发生场景
Source(s): https://github.com/anthropics/claude-code/issues/15112 Status: reported fixed by source, not reproduced by us.
问题
claude --mcp-config <file> (or --settings) with the file in /tmp crashes inside the VS Code/Cursor terminal.
报错原文（已脱敏/规范化）
Error: ENXIO: no such device or address, watch '/tmp/<...>.sock'
如何确认是这个问题
Error names a .sock file under /tmp and the config path is in /tmp.
根因
Claude Code watches the directory of the passed config; socket files in /tmp (IDE IPC, other tools) cannot be watched.
修复步骤
- Use a project
.mcp.json, or runclaudefrom a terminal outside the IDE (the reporter confirmed these work). - Or store the config outside /tmp (e.g. ~/.cache/<app>/) - suggested by a commenter, not confirmed.
TMPDIR=/tmp/claude-tmp(create it first): reports conflict - the OP says it did not help, another user says it worked.
如何验证
The same command starts without ENXIO.
