MySQL MCP Server

A Model Context Protocol (MCP) implementation that enables secure interaction with MySQL databases. This server component facilitates communication between AI applications (hosts/clients) and MySQL databases, making database exploration and analysis safer and more structured through a controlled interface.

Note: MySQL MCP Server is not designed to be used as a standalone server, but rather as a communication protocol implementation between AI applications and MySQL databases.

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

Manual Installation

pip install mysql-mcp-server

Installing via Smithery

To install MySQL MCP Server for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install mysql-mcp-server --client claude

Configuration

Set the following environment variables:

MYSQL_HOST=localhost # Database host MYSQL_PORT=3306 # Optional: Database port (defaults to 3306 if not specified) MYSQL_USER=your_username MYSQL_PASSWORD=your_password MYSQL_DATABASE=your_database

Usage

With Claude Desktop

Add this to your claude_desktop_config.json:

{ "mcpServers": { "mysql": { "command": "uv", "args": [ "--directory", "path/to/mysql_mcp_server", "run", "mysql_mcp_server" ], "env": { "MYSQL_HOST": "localhost", "MYSQL_PORT": "3306", "MYSQL_USER": "your_username", "MYSQL_PASSWORD": "your_password", "MYSQL_DATABASE": "your_database" } } } }

With Visual Studio Code

Add this to your mcp.json:

{ "servers": { "mysql": { "type": "stdio", "command": "uvx", "args": [ "--from", "mysql-mcp-server", "mysql_mcp_server" ], "env": { "MYSQL_HOST": "localhost", "MYSQL_PORT": "3306", "MYSQL_USER": "your_username", "MYSQL_PASSWORD": "your_password", "MYSQL_DATABASE": "your_database" } } } }

Note: Will need to install uv for this to work

Debugging with MCP Inspector

While MySQL MCP Server isn't intended to be run standalone or directly from the command line with Python, you can use the MCP Inspector to debug it.

The MCP Inspector provides a convenient way to test and debug your MCP implementation:

# Install dependencies pip install -r requirements.txt # Use the MCP Inspector for debugging (do not run directly with Python)

The MySQL MCP Server is designed to be integrated with AI applications like Claude Desktop and should not be run directly as a standalone Python program.

Development

# Clone the repository git clone https://github.com/designcomputer/mysql_mcp_server.git cd mysql_mcp_server # Create virtual environment python -m venv venv source venv/bin/activate # or `venv\Scripts\activate` on Windows # Install development dependencies pip install -r requirements-dev.txt # Run tests pytest

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 implementation 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.
