The server implements a token bucket algorithm for rate limiting to comply with Trello's API limits:

• 300 requests per 10 seconds per API key
• 100 requests per 10 seconds per token

Rate limiting is handled automatically, and requests will be queued if limits are reached.

The server provides detailed error messages for various scenarios:

• Invalid input parameters
• Rate limit exceeded
• API authentication errors
• Network issues
• Invalid board/list/card IDs

• Node.js 16 or higher
• npm or yarn
