• server.py:45-63 (handler)

  Handler function for the show_video_tool MCP tool. Registered via @mcp.tool() decorator. Calls the chunk_video helper to create a video clip from the specified document between start_time and end_time, saves it, and returns a success message.

Args: document_name (str): The name of the document the chunk belongs to start_time (float): The start time of the chunk end_time (float): The end time of the chunk Returns: str: A message indicating that the video chunk was created successfully """ try: chunk_video(document_name, start_time, end_time) return "Video chunk created successfully" except Exception as e: return f"Failed to create video chunk: {str(e)}"
• main.py:111-126 (helper)

  Supporting helper function that implements the core video chunking logic using moviepy.VideoFileClip. Loads video from 'videos/{document_name}', extracts subclip from start_time to end_time (clamped to duration), saves as mp4 in 'video_chunks/' directory.
