Toolhouse MCP Server
# 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
```bash
pip install mysql-mcp-server
```
## Configuration
Set the following environment variables:
```bash
MYSQL_HOST=localhost
MYSQL_USER=your_username
MYSQL_PASSWORD=your_password
MYSQL_DATABASE=your_database
```
## Usage
### With Claude Desktop
Add this to your `claude_desktop_config.json`:
```json
{
"mcpServers": {
"mysql": {
"command": "uv",
"args": [
"--directory",
"path/to/mysql_mcp_server",
"run",
"mysql_mcp_server"
],
"env": {
"MYSQL_HOST": "localhost",
"MYSQL_USER": "your_username",
"MYSQL_PASSWORD": "your_password",
"MYSQL_DATABASE": "your_database"
}
}
}
}
```
### As a standalone server
```bash
# Install dependencies
pip install -r requirements.txt
# Run the server
python -m mysql_mcp_server
```
## Development
```bash
# Clone the repository
git clone https://github.com/yourusername/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 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](https://github.com/designcomputer/mysql_mcp_server/blob/main/SECURITY.md) 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.
