Overview

What is MCP + openGauss?

MCP + openGauss is an MCP server that bridges the Model Context Protocol (MCP) with the openGauss database. It enables LLM agents to interact with openGauss through a standardized protocol, allowing natural‑language queries and database operations.

How to use MCP + openGauss?

Install Python 3 and uv.
Deploy openGauss (e.g., via container) and start it.
Download the openGauss_mcp_server source code (version 0.1.0).
In Claude Desktop’s configuration file, add a mcpServers entry that points uv to the server’s directory and sets the required environment variables (OPENGAUSS_HOST, PORT, USER, PASSWORD, DBNAME).
Restart Claude Desktop; the MCP tools become available, and you can run database queries by talking to Claude.
