Complete Workflow Example

1. Configure Claude Desktop - Add the MCP server to your claude_desktop_config.json:

   {
     "mcpServers": {
       "youtube-mcp-tools": {
         "command": "/opt/homebrew/bin/uv",
         "args": [
           "--directory",
           "/Users/granludo/code/testing/youtube_download",
           "run",
           "start_server.py"
         ]
       }
     }
   }

2. Download a video in Claude:

   "Download this YouTube video: https://www.youtube.com/watch?v=jNQXAC9IVRw"

   The server will start the download and return a job ID immediately.

3. Check download status:

   "What's the status of that download?"

4. List all downloads:

   "Show me all my download jobs"
