MCP + openGauss

随着AI从静态推理向动态交互演进,智能体(Agent)逐渐成为焦点。Agent不仅能够调用LLM进行推理,还能访问数据库、调用API、执行任务。然而,当前LLM和Agent之间缺乏标准化交互协议, 每个新数据源都需要自定义实现,使得真正互联的系统难以扩展。MCP(Model Context Protocol, 模型上下文协议)解决了这一挑战,MCP是为LLM和Agent系统设计的标准化交互框架,使LLM可以与外部数据库、API和工具进行高效交互。

快速搭建openGauss + MCP + LLM的AI Agent应用

环境准备

  • 安装python3环境,安装uv。
  • 通过容器部署并启动openGauss数据库。(openGauss官网:学习->文档->最新开发版本->安装指南->容器镜像安装)
  • 下载Claude Desktop配合MCP协议进行问答操作。

获取openGauss_mcp_server源码

访问链接, 获取openGauss_mcp_server源码,当前版本为(0.1.0)。

配置参数

  • 打开Claude Desktop设置,编辑配置文件。

  • 通过Edit Config增加配置
{
    "mcpServers": {
        "openGauss": {
            "command": "uv",
            "args": [
            "--directory",
            "path/to/openGauss_mcp_server",
            "run",
            "server.py"
            ],
            "env": {
                "OPENGAUSS_HOST": "localhost",
                "OPENGAUSS_PORT": "8888",
                "OPENGAUSS_USER": "your_username",
                "OPENGAUSS_PASSWORD": "your_password",
                "OPENGAUSS_DBNAME": "your_database"
            }
        }
    }
}
