Project description
mysql-mcp-pro
一个生产级的 MySQL MCP Server,让 AI 助手(Claude Desktop / WorkBuddy / Cursor / Cline 等)通过标准化协议安全高效地操作 MySQL 数据库。
✨ 为什么选 mysql-mcp-pro?
相比社区其他 MySQL MCP 实现,本项目提供了更完整的能力集:
| 特性 | mysql-mcp-pro | 其他 MCP |
|---|---|---|
| 连接池(减少握手开销) | ✅ | ❌ |
| 事务支持(begin/commit/rollback) | ✅ | ❌ |
| EXPLAIN 自动解读 | ✅ | ❌ |
| 结果导出 CSV/JSON(Excel 友好 BOM) | ✅ | ❌ |
| ER 关系图数据(nodes/edges) | ✅ | 少数 |
| 视图 / 存储过程 / 函数 / 触发器 浏览 | ✅ | 少数 |
| 查询历史 & 审计日志 | ✅ | ❌ |
| MCP Prompts 模板(生成/优化/对比/概览) | ✅ | ❌ |
| 安全分级(只读/DDL/危险语句/超时/行限/参数化) | ✅ | 基础 |
| 多传输模式(stdio / SSE / streamable-http) | ✅ | 部分 |
🚀 快速开始
1. 安装
# 从源码(推荐先 clone 再使用)
git clone https://github.com/CCCT173/mysql-mcp-pro.git
cd mysql-mcp-pro
pip install -e .
# 或从 PyPI(待发布)
pip install mysql-mcp-pro
2. 配置环境变量
复制 .env.example 为 .env 并编辑:
MYSQL_HOST=localhost
MYSQL_PORT=3306
MYSQL_USER=root
MYSQL_PASSWORD=your_password
MYSQL_DATABASE=your_database
READ_ONLY=false # 只读模式
ALLOW_DDL=false # 是否允许 CREATE/ALTER/DROP
MAX_RESULT_ROWS=1000 # 单次查询最大返回行数
QUERY_TIMEOUT=30 # 查询超时(秒)
POOL_SIZE=5
AUDIT_LOG=true # 审计日志
EXPORT_DIR=./exports # 导出目录
3. 在你的 MCP 客户端注册
WorkBuddy
编辑 ~/.workbuddy/mcp.json:
{
"mcpServers": {
"mysql": {
"command": "python",
"args": ["-m", "server"],
"cwd": "D:/path/to/mysql-mcp-pro",
"env": {
"MYSQL_HOST": "localhost",
"MYSQL_PORT": "3306",
"MYSQL_USER": "root",
"MYSQL_PASSWORD": "your_password",
"MYSQL_DATABASE": "your_database"
}
}
}
}
或者如果你已经 pip install -e .:
{
"mcpServers": {
"mysql": {
"command": "mysql-mcp-pro",
"env": {
"MYSQL_HOST": "localhost",
"MYSQL_PORT": "3306",
"MYSQL_USER": "root",
"MYSQL_PASSWORD": "your_password",
"MYSQL_DATABASE": "your_database"
}
}
}
}
Claude Desktop
编辑 ~/Library/Application Support/Claude/claude_desktop_config.json(macOS)或 %APPDATA%/Claude/claude_desktop_config.json(Windows):
{
"mcpServers": {
"mysql": {
"command": "mysql-mcp-pro",
"env": {
"MYSQL_HOST": "localhost",
"MYSQL_PORT": "3306",
"MYSQL_USER": "root",
"MYSQL_PASSWORD": "your_password",
"MYSQL_DATABASE": "your_database",
"READ_ONLY": "true"
}
}
}
}
Cursor / Cline
在项目根目录创建 .cursor/mcp.json(Cursor)或在 Cline 设置中添加,格式同上。
Tools
Tools are automatically extracted by MCP registries (Smithery, mcp.so, glama, etc.).
- ping — Test MySQL connection; returns server version and connection-pool stats.
- get_server_status — Key MySQL status metrics (connections, QPS, slow queries, InnoDB rows, traffic).
- list_databases — List all databases (system vs user).
- list_tables — List tables with engine, row count, size, comment. Optional
databaseargument. - describe_table — Show table schema: columns, primary key, indexes, foreign keys, CREATE SQL. Arguments:
table(required),database(optional). - list_views — List views in the database.
- list_routines — List stored procedures or functions. Arguments:
routine_type(PROCEDURE/FUNCTION),database. - list_triggers — List triggers in the database.
- er_graph — Cross-table foreign-key graph as nodes + edges, ready for ER diagrams.
- execute_query — Execute any SQL (read/write/DDL, safety-guarded), parameterized. Arguments:
sql,database,params,session_id. - execute_select — Read-only SELECT/SHOW/DESCRIBE/EXPLAIN with extra safety layer. Arguments:
sql,database,params,limit. - get_table_data — Quick paginated table fetch. Arguments:
table,columns,where,order_by,limit,offset. - count_rows — Count rows in a table with optional WHERE. Arguments:
table,database,where. - explain_query — Run
EXPLAINon a query and return plain-language performance insights. Arguments:sql,database,params,format. - export_query — Export SELECT results to a CSV (UTF-8 BOM, Excel-friendly) or JSON file. Arguments:
sql,filename,format(csv/json),database,params. - list_query_history — Recent SQL executed in this session (duration, row count, errors). Argument:
limit. - begin_transaction — Start a new transaction; returns a
session_idfor chained calls. Argument:database. - commit_transaction — Commit an open transaction. Argument:
session_id. - rollback_transaction — Rollback an open transaction. Argument:
session_id. - show_processlist — Show the current MySQL process list (
SHOW FULL PROCESSLIST). - kill_query — Kill a MySQL process (requires SUPER privilege). Argument:

🛠 工具一览(25 个)
连接 & 状态
ping— 测试连接、返回服务器版本与连接池状态get_server_status— MySQL 关键指标(连接数、QPS、慢查询、流量等)

begin_transaction— 开启事务,返回 session_idcommit_transaction— 提交事务rollback_transaction— 回滚事务
监控 & 管理
show_processlist— 当前 MySQL 进程列表kill_query— Kill 指定进程(需要 SUPER 权限)
MCP Resources(4 个)
mysql://databases— 数据库列表mysql://tables/{database}— 表列表mysql://schema/{database}/{table}— 表结构mysql://er/{database}— ER 关系图数据
MCP Prompts(4 个模板)
generate_query— 根据自然语言和表信息生成 SQLoptimize_sql— 分析并优化现有 SQL 性能compare_schema— 对比两张表的结构差异database_summary— 数据库整体概览报告
🔒 安全模型
危险语句(GRANT/REVOKE/SHUTDOWN/KILL/FLUSH/RESET)→ 永远禁止
DDL(CREATE/ALTER/DROP/RENAME/TRUNCATE) → 由 ALLOW_DDL 控制
写操作(INSERT/UPDATE/DELETE) → 由 READ_ONLY 控制
读操作(SELECT/SHOW/DESCRIBE/EXPLAIN) → 永远允许
- 参数化查询
%s占位符,杜绝 SQL 注入 - 结果集默认 1000 行上限,防止意外返回海量数据
- 服务端
MAX_EXECUTION_TIME强制查询超时 - 所有执行 SQL 落盘到
exports/audit.log
