YouTube Gemini MCP Server

A Model Context Protocol (MCP) server that provides conversational YouTube video analysis capabilities using Gemini 2.5 Pro. Analyze videos through multi-turn conversations with advanced visual understanding.

🎯 What Problems Does This Solve?

Traditional Video Analysis Pain Points

❌ Transcript-only limitations - Missing visual context and scene understanding
❌ No conversation memory - Each analysis starts from scratch
❌ Manual workflows - Complex download/upload processes

Our Solution

✅ Full video analysis - Visual, audio, and contextual understanding
✅ Session memory - Builds on previous analysis automatically
✅ Integrated workflows - YouTube URL to analysis in one step

🚀 Key Capabilities

🔄 Session-Based Video Conversations

Create persistent sessions for multi-turn video analysis:

# Create session
create_video_session(
    description="Analyze machine learning lecture",
    video_source="https://youtube.com/watch?v=abc123",
    source_type="youtube_url"
)

# Continue conversation
analyze_video_in_session(session_id="uuid", prompt="What are the key concepts?")
analyze_video_in_session(session_id="uuid", prompt="Explain the neural networks part")

📹 Direct YouTube Processing

No downloads required - process YouTube videos directly:

analyze_youtube_video(
    youtube_url="https://youtube.com/watch?v=abc123",
    prompt="Summarize this video's main points"
)

💾 Local Video Support

Upload and analyze local video files (48-hour retention):

analyze_local_video(
    video_path="/path/to/video.mp4",
    prompt="What happens in this video?"
)
