mysql-mcp-server
Provides tools for executing SQL queries, retrieving database table structures, and checking database connection status in a MySQL database.
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@mysql-mcp-serverShow me the structure of the orders table"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.

主要功能
执行 SQL 查询(SELECT、INSERT、UPDATE、DELETE)
获取数据库表结构信息
检测数据库连接状态
SQL 语句和参数安全校验
优雅的服务启动与关闭
架构说明
入口文件:
src/index.js启动和管理 MCP 服务器实例服务实现:
src/server.js实现 MCP Server,注册工具、处理请求数据库管理:
src/database.js管理 MySQL 连接池、执行 SQL、获取表结构配置管理:
src/config.js支持 .env 环境变量和默认配置安全校验:
src/validators.js校验 SQL 语句和参数,防止危险操作和注入
安装与使用
克隆项目
git clone https://github.com/yourname/mcp-mysql-server.git cd mcp-mysql-server安装依赖
npm install配置数据库连接(可选,支持 .env 文件)
DB_HOST=localhost DB_PORT=3306 DB_USER=root DB_PASSWORD=yourpassword DB_NAME=yourdatabase启动服务
node src/index.js
配置说明
支持通过环境变量或
.env文件配置数据库和服务参数主要配置项见
src/config.js
主要实现细节
使用
mysql2/promise实现高效的连接池和异步 SQL 执行所有 SQL 语句和参数均经过安全校验,防止危险操作和 SQL 注入
MCP Server 支持三大工具:
execute_sql:执行 SQL 查询get_tables_info:获取所有表及字段结构get_connection_status:检测数据库连接
优雅处理进程信号,支持平滑关闭
安全性说明
禁止 DROP/TRUNCATE/ALTER 等危险操作
检查常见 SQL 注入模式
限制参数数量,防止滥用
禁用多语句执行
在 Cursor 中 验证 开发的 MCP Server 是否能运行
Cursor 添加 MCP Server
通过 Cursor Settings -> MCP Add new global MCP server,可以将 MCP 服务添加为全局可用。这意味着你配置的 MCP 服务将在所有项目中生效。
也可以只针对 项目级别 添加
在项目的 .cursor目录下,新建一个 mcp.json文件进行配置,这样的设置只会对特定项目生效。

mcp server 的格式是如何呢

配置 server 基本格式规范
{
"mcpServers": {
"<server-name>": {
"command": "<启动命令>",
"args": ["<参数1>", "<参数2>", ...],
"env": {
"<环境变量名1>": "<值1>",
"<环境变量名2>": "<值2>",
...
},
"transport": "<传输协议>",
"port": <端口号>,
"host": "<主机地址>"
}
}
}查询数据库表和字段信息

查看当前数据库是否连接
查询表里数据

看到这里,是不是觉得很神奇?我们用自然语言描述需求,AI助手自动生成并执行SQL,然后分析结果给出结论。
