The MySQL MCP Server provides a secure interface for AI assistants to interact with MySQL databases by listing tables, reading data, and executing queries. It focuses on safe and structured database exploration with comprehensive logging and minimal permission requirements.

MySQL MCP Server

A Model Context Protocol (MCP) server that enables secure interaction with MySQL databases. This server allows AI assistants to list tables, read data, and execute SQL queries through a controlled interface, making database exploration and analysis safer and more structured.

Features

  • List available MySQL tables as resources
  • Read table contents
  • Execute SQL queries with proper error handling
  • Secure database access through environment variables
  • Comprehensive logging

Installation

git clone https://github.com/he426100/mysql-mcp-server
cd mysql-mcp-server
composer install

Configuration

Set the following environment variables:

DB_HOST=localhost     # Database host
DB_PORT=3306         # Optional: Database port (defaults to 3306 if not specified)
DB_USERNAME=your_username
DB_PASSWORD=your_password
DB_DATABASE=your_database

Usage

As a standalone server

# Install dependencies
composer install

# Run the server
php bin/console

docker

docker build -t mysql-mcp-server .
docker run -i --rm mysql-mcp-server --host 127.0.0.1

Security Considerations

  • Never commit environment variables or credentials
  • Use a database user with minimal required permissions
  • Consider implementing query whitelisting for production use
  • Monitor and log all database operations

Security Best Practices

This MCP server requires database access to function. For security:

  1. Create a dedicated MySQL user with minimal permissions
  2. Never use root credentials or administrative accounts
  3. Restrict database access to only necessary operations
  4. Enable logging for audit purposes
  5. Regular security reviews of database access

See MySQL Security Configuration Guide for detailed instructions on:

  • Creating a restricted MySQL user
  • Setting appropriate permissions
  • Monitoring database access
  • Security best practices

⚠️ IMPORTANT: Always follow the principle of least privilege when configuring database access.
