MCP-MongoDB-MySQL-Server
这是一个基于 enemyrr/mcp-mysql-server 项目的二次开发版本，添加了MongoDB支持。 This is a fork of enemyrr/mcp-mysql-server with added MongoDB support.
项目简介 | Introduction
这是一个Model Context Protocol服务器，提供MySQL和MongoDB数据库操作功能。该服务器使AI模型能够通过标准化接口与MySQL和MongoDB数据库交互。
A Model Context Protocol server that provides MySQL and MongoDB database operations. This server enables AI models to interact with MySQL and MongoDB databases through a standardized interface.
二次开发说明 | About This Fork
作者 | Author: yaoxiaolinglong
二次开发原因 | Reason for Fork: 原项目只支持MySQL数据库，但在实际应用中经常需要使用MongoDB。由于找不到现成的MongoDB MCP工具，因此在原项目基础上添加了MongoDB支持，使其成为一个同时支持MySQL和MongoDB的数据库服务器。
The original project only supports MySQL database, but MongoDB is often needed in practical applications. Due to the lack of ready-made MongoDB MCP tools, MongoDB support was added to the original project, making it a database server that supports both MySQL and MongoDB.

});MongoDB配置 | MongoDB Configuration
您可以通过以下三种方式配置MongoDB数据库连接：
You can configure the MongoDB database connection in three ways:
- .env文件中的MongoDB URL（推荐）| MongoDB URL in .env (Recommended):
