🚨 Error Handling

Retry Strategy

• Automatic Retries: Up to 5 attempts by default (configurable)
• Exponential Backoff: 2s, 4s, 8s delays
• Rate Limiting: 500KB/s limit with 2-second sleep intervals
• Graceful Degradation: Return partial results when possible

Error Types

• YouTubeExtractorError: Extraction-specific errors
• InvalidURLError: Invalid YouTube URL format
• RuntimeError: General execution errors

Troubleshooting

Rate Limiting Issues

If you encounter rate limiting:

1. Increase sleep intervals in .env: YOUTUBE_RETRY_DELAY=3.0
2. Lower rate limit: YOUTUBE_RATE_LIMIT=300K
3. Reduce concurrent requests

yt-dlp Not Working

1. Ensure uv is installed: uv --version
2. Verify yt-dlp installation: uv run yt-dlp --version
3. The server automatically uses uv run yt-dlp if direct access fails

MCP Connection Issues

1. Restart your MCP client after code changes
2. Check logs for specific error messages
3. Verify environment variables are loaded correctly

🔧 Development

Running the Server

⚠️ Always use uv run to ensure proper dependency management:

# Start the MCP server (recommended)
uv run python -m src.youtube_mcp_server.server

# Or if you have a run_server.py file
uv run python run_server.py

Testing

# Run all tests
uv run pytest tests/

# Run specific test file
uv run pytest tests/test_basic.py

# Run with coverage
uv run pytest --cov=src tests/
