MySQL MCP Server

A Model Context Protocol (MCP) server for MySQL databases that enables AI models to interact with MySQL databases through a structured interface.

Overview

The MySQL MCP Server provides a bridge between AI models and MySQL databases, allowing AI agents to query and analyze MySQL data. This implementation follows the Model Context Protocol specification and offers both web server and CLI modes of operation.

Features

• MySQL database connection management
• SQL query execution
• Table listing and structure inspection
• Database listing and selection
• Real-time status monitoring via SSE (Server-Sent Events)
• Web interface for testing MCP tools
• Support for both stdio and SSE transport methods
• Docker deployment ready

Installation

# Global installation
npm install -g mysql-mcp

# Local installation
npm install mysql-mcp

Using with AI Assistants

Using the Published Server on Smithery.ai

The MySQL MCP Server is published on Smithery.ai and can be easily used with various AI assistants:

1. Access the server: Visit https://smithery.ai/server/@sussa3007/mysql-mcp

2. Configure the server:

   • Set your MySQL database connection details:
     • MYSQL_HOST
     • MYSQL_PORT
     • MYSQL_USER
     • MYSQL_PASSWORD
     • MYSQL_DATABASE
     • MYSQL_READONLY (optional, set to True for read-only access)

3. Connect with supported AI platforms:

   • Anthropic Claude
   • Cursor AI
   • Windsurf
