cursor使用mcp

问题说明

mcp就相当于给AI安装了工具包，它可以调用获取接口文档，网页，数据库等，基本上所有的mcp都是node程序，少数需要python环境

使用说明

使用mcp-mysql举例，下面是配置json

"mysql": {"command": "cmd","args": ["/c","npx","-y","@f4ww4z/mcp-mysql-server"],"env": {"MYSQL_HOST": "","MYSQL_USER": "","MYSQL_PASSWORD": ".","MYSQL_DATABASE": ""}
}

可以看到启动命令就是 cmd /c npx -y @f4ww4z/mcp-mysql-server

npx 命令会去查找这个模块：

1. 先查当前项目的 node_modules/.bin
2. 找不到再临时下载到缓存目录
3. 执行脚本

npm config get prefix
可以查看当前node的缓存目录

查看启动日志，output选择mcp logs

我遇到的报错问题，就是缺少相关依赖，需要管理员cmd，所以我们可以手动进行全局安装

npm -g install @f4ww4z/mcp-mysql-server

在回到cursor就变成绿点就没有问题了

常用mcp

1. 获取浏览器控制台还需要安装浏览器插件
2. APIFOX文档获取
3. 读取MYSQL数据库

{"mcpServers": {"browser-tools-mcp": {"command": "cmd","args": ["/c","npx","-y","@agentdeskai/browser-tools-mcp@1.2.0"]},"API 文档": {"command": "cmd","args": ["/c","npx","-y","apifox-mcp-server@latest","--project="],"env": {"APIFOX_ACCESS_TOKEN": ""}},"mysql": {"command": "cmd","args": ["/c","npx","-y","@f4ww4z/mcp-mysql-server"],"env": {"MYSQL_HOST": "","MYSQL_USER": "","MYSQL_PASSWORD": ".","MYSQL_DATABASE": ""}}}
}
