Highgo MCP Server (瀚高数据库 MCP 服务)

这是一个基于 Model Context Protocol (MCP) 实现的瀚高数据库 (Highgo Database) 服务。它允许 AI 智能体（如 Claude Desktop, Gemini CLI 等）直接连接、查询和分析瀚高数据库中的数据。

特性

SQL 执行: 支持执行任意 SQL 语句，包括瀚高特有的 SM3 加密和语法。
Schema 管理: 支持通过 search_path 动态切换工作 schema。
元数据查询: 快速列出库中的表结构、字段类型及注释。
独立分发: 支持通过 npx 直接运行，无需全局安装。

快速开始

1. 前置条件

已安装 Node.js (建议 v18+)
瀚高数据库的连接信息

2. 数据库配置

在项目根目录下创建一个 .env 文件，或者在运行环境中设置以下环境变量：

HIGHGO_HOST=172.22.*.*
HIGHGO_PORT=5866
HIGHGO_USER=用户名
HIGHGO_PASSWORD=您的密码
HIGHGO_DATABASE=数据库名

3. 使用 npx 运行 (推荐)

如果您在本地开发，可以直接在项目目录运行：

npx .

如果您已将其发布到 NPM 或作为 Git 依赖引用，可以远程运行：

npx highgo-mcp-server

在 AI 智能体中配置

Claude Desktop

{
  "mcpServers": {
    "highgo": {
      "command": "npx",
      "args": ["-y", "/path/to/highgo-mcp"],
      "env": {
        "HIGHGO_HOST": "172.22.*.*",
        "HIGHGO_USER": "用户名",
        "HIGHGO_PASSWORD": "您的密码",
        "HIGHGO_DATABASE": "数据库名"
      }
    }
  }
}

Gemini CLI

在配置文件中添加类似的条目。
