README

dm8-mcp-server

基于 Spring AI MCP 实现的达梦数据库(DM8)MCP Server,支持通过 AI 助手(如 Claude)查询 DM8 数据库的 Schema、表结构等信息。

功能

工具 描述
listSchemas 列出数据库中所有 Schema
listTables 列出指定 Schema 下的所有表名
describeTable 查询指定表的列信息(列名、类型、长度、是否可空、注释)
getTableDdl 获取指定表的 DDL 建表语句
listTableIndexes 查询指定表的索引信息(索引名、是否唯一、索引类型、索引列)
listTableConstraints 查询指定表的约束信息(主键/唯一键/外键/检查约束)
listViews 列出指定 Schema 下的所有视图及其定义
executeQuery 执行只读 SELECT 查询(禁止任何写操作)

环境要求

  • Java 17+
  • Maven 3.6+
  • 达梦数据库 DM8
  • DM8 JDBC 驱动(DmJdbcDriver18.jar)

构建步骤

1. 克隆项目

git clone https://github.com/KaKaLuoTeSun/dm8-mcp-server.git
cd dm8-mcp-server

2. 放入 DM8 驱动

将 DmJdbcDriver18.jar 复制到项目 lib/ 目录下:

dm8-mcp-server/
└── lib/
    └── DmJdbcDriver18.jar   ← 放这里

驱动文件可从达梦数据库安装目录的 drivers/jdbc/ 下找到。

3. 打包

mvn clean package -DskipTests

打包成功后,在 target/ 目录下生成 dm8-mcp-1.0.0.jar。

配置 Claude Desktop

编辑 Claude Desktop 配置文件:

  • Windows:%APPDATA%\Claude\claude_desktop_config.json
  • macOS:~/Library/Application Support/Claude/claude_desktop_config.json

在 mcpServers 中添加以下配置:

{
  "mcpServers": {
    "dm8": {
      "command": "java",
      "args": ["-jar", "C:\\path\\to\\dm8-mcp-1.0.0.jar"],
      "env": {
        "DM8_URL": "jdbc:dm://127.0.0.1:5236",
        "DM8_USERNAME": "SYSDBA",
        "DM8_PASSWORD": "your_password"
      }
    }
  }
}

将 args 中的路径替换为实际的 jar 文件路径,将 env 中的连接信息替换为实际的数据库连接信息。

配置完成后,重启 Claude Desktop 使配置生效。

使用示例

配置成功后,可以在 Claude 对话中直接提问:

  • "列出数据库中所有的 schema"
  • "查看 DMHR 下有哪些表"
  • "描述一下 DMHR.CITY 表的结构"
  • "获取 DMHR.CITY 表的 DDL"
  • "查看 DMHR.DEPARTMENT 表有哪些索引"
  • "查看 DMHR.EMPLOYEE 表的约束信息"
  • "列出 DMHR 下所有视图"
  • "执行 SELECT * FROM DMHR.CITY WHERE ROWNUM <= 10"

技术栈
