## Configuration

The application will create a default configuration file at `~/.config/youtube_cli/config.json` if one doesn't exist. You can customize:

```json
{
  "download_dir": "~/Downloads/youtube",
  "default_locations": [
    "~/Downloads/youtube",
    "~/Movies/youtube",
    "/tmp/youtube"
  ],
  "max_videos_per_page": 15,
  "yt_dlp_args": {
    "format": "bestvideo[height=1080]+bestaudio/bestvideo[height<=1080]+bestaudio",
    "write_thumbnail": true,
    "extractor_args": "youtube:player-client=default,-tv_simply"
  },
  "network_share_path": "/Volumes/MediaServer/Youtube/",
  "default_network_subfolder": "General"
}
```

## How to Use

2. Videos will be displayed with:
   - Title (short videos marked with "(short)")
   - Author
   - Duration
   - Type indicator (Video, Short, Playlist)
3. Choose an option:
   - `n` for next page of results

```bash
pip install yt-dlp
```

## API Development

The application includes a Flask-based REST API for programmatic access:

```bash
# Run the API server
python app.py
```

The API will be available at `http://localhost:4096`

## Docker Support

The application can be run in Docker:

```bash
docker-compose up
```

This will start the API server on port 4096.

## Contributing

1. Fork it
2. Create your feature branch (`git checkout -b feature/AmazingFeature`)
3. Commit your changes (`git commit -m 'Add some AmazingFeature'`)
4. Push to the branch (`git push origin feature/AmazingFeature`)

## MCP Integration

This project supports Model Context Protocol (MCP) integration, allowing it to work with AI agents and tools that require MCP-compliant interfaces. The API endpoints provide capabilities that can be used by MCP servers to interact with YouTube content.

## Network Share Support

The application supports copying downloaded videos to network shares. Configure the `network_share_path` in your configuration file to enable this feature.

## Download Archive

The application maintains an archive of downloaded videos to prevent duplicate downloads. This archive is stored in `~/.config/youtube_cli/downloaded_videos.json`.

## Advanced Usage

### Download Multiple Videos
```
youtube-cli "python tutorial"
# When prompted, enter: 1,2,3
```

### Download Video Range
```
youtube-cli "python tutorial"
# When prompted, enter: 1-5
```

### Custom Download Locations
```
youtube-cli --download "https://www.youtube.com/watch?v=xyz123"
# When prompted, enter a network folder name to copy to network share
```

### Update Management
```
youtube-cli --check-update
youtube-cli --update
```

## Troubleshooting

### JavaScript Challenges
If you encounter JavaScript challenge solving errors:
```bash
yt-dlp --remote-components ejs:github
```

### Permission Issues
Ensure proper permissions for download directories:
```bash
mkdir -p ~/Downloads/youtube
chmod 755 ~/Downloads/youtube
```

### API Issues
If the API server fails to start:
```bash
pip install -r requirements-api.txt
```
