Security Considerations

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:

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