MySQL MCP Server
Allows AI to execute SQL queries, list tables, and describe table structures in a MySQL database.
Click on "Deploy 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 Serverlist all tables in the database"
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.
MySQL MCP Server
MySQL MCP Server 是一个为 Cursor 编辑器设计的 Model Context Protocol (MCP) 服务器,让 AI 助手能够直接查询 MySQL 数据库。
✨ 功能特性
🔍 执行 SQL 查询
📋 列出所有数据表
📊 查看表结构
🔒 安全的环境变量配置
⏱️ 可配置查询超时,防止SQL卡死
🚀 开箱即用,通过 npx 快速启动

📦 安装
方式 1: 使用 npx (推荐)
无需安装,直接在 mcp.json 中配置:
{
"mcpServers": {
"mysql": {
"command": "npx",
"args": ["-y", "@keevor/mysql-mcp-server"],
"env": {
"DB_HOST": "localhost",
"DB_PORT": "3306",
"DB_USER": "root",
"DB_PASSWORD": "your_password",
"DB_DATABASE": "your_database",
"DB_QUERY_TIMEOUT": "10"
}
}
}
}方式 2: 全局安装
npm install -g @keevor/mysql-mcp-server然后在 mcp.json 中配置:
{
"mcpServers": {
"mysql": {
"command": "mysql-mcp-server",
"env": {
"DB_HOST": "localhost",
"DB_PORT": "3306",
"DB_USER": "root",
"DB_PASSWORD": "your_password",
"DB_DATABASE": "your_database",
"DB_QUERY_TIMEOUT": "10"
}
}
}
}🔧 配置说明
通过环境变量配置数据库连接:
环境变量 | 必需 | 默认值 | 说明 |
| ✅ 是 | - | 数据库主机地址 |
| ❌ 否 | 3306 | 数据库端口 |
| ✅ 是 | - | 数据库用户名 |
| ❌ 否 | "" | 数据库密码 |
| ✅ 是 | - | 数据库名称 |
| ❌ 否 | utf8mb4 | 字符集 |
| ❌ 否 | 10 | 查询超时时间(秒) |
🛠️ 可用工具
在 Cursor 中,AI 可以调用以下工具:
1. query - 执行 SQL 查询
// 示例
query({ sql: "SELECT * FROM users LIMIT 10" })2. list_tables - 列出所有数据表
// 示例
list_tables()3. describe_table - 查看表结构
// 示例
describe_table({ table: "users" })📍 配置文件位置
在 Cursor 中,mcp.json 配置文件的位置:
Windows:
%APPDATA%\Cursor\User\globalStorage\rooveterinaryinc.roo-cline\settings\mcp.jsonmacOS:
~/Library/Application Support/Cursor/User/globalStorage/rooveterinaryinc.roo-cline/settings/mcp.jsonLinux:
~/.config/Cursor/User/globalStorage/rooveterinaryinc.roo-cline/settings/mcp.json
🚀 使用示例
在 Cursor 中配置好 MCP 服务器后,你可以这样与 AI 对话:
"查询 users 表中的所有数据"
"列出数据库中的所有表"
"查看 orders 表的结构"
🔒 安全提示
⚠️ 不要在公开的代码仓库中提交包含数据库密码的
mcp.json文件⚠️ 建议使用只读账户或限制权限的数据库账户
⚠️ 在生产环境中使用时要特别小心
