常见报错排查与运行避坑 (Troubleshooting)FAQ

针对 MCP Retrieval 在 Cursor、Claude Code 中的常见连接错误与解决办法

在 Cursor / Claude Code 中配置 MCP Retrieval 提示 connection closed 或 exit code 1？

通常由本地运行时环境缺失或命令路径未被 IDE 继承引起。排查步骤： 1. 确认已安装 Node.js 18+（支持 npx）或 Python 3.10+（支持 uvx）； 2. 尝试在终端运行 which npx 或 which uvx，把配置文件中的 "command" 字段改为完整绝对路径； 3. 修改 mcp.json 后，必须完全重载或重启客户端窗口。

Fix Snippet
# 终端测试命令是否存在：
which npx
node -v
提示 spawn npx ENOENT 或 command not found？

这是因为编辑器后台进程未加载完整的终端环境变量（PATH）。解决方案：在全局安装该包（如 npm install -g 包名），或在配置文件中将 command 设置为系统的实际路径（如 Windows 下的 C:\Program Files\nodejs\npx.cmd，Mac 下的 /usr/local/bin/npx）。
