Test with Cursor by asking it to search YouTube content

Custom Project Integration

For custom applications or other MCP clients:

from youtube_mcp_server import (
    get_video_details,
    search_videos,
    evaluate_video_for_knowledge_base
)

# Example usage
async def example():
    # Search for videos
    results = await search_videos("machine learning", max_results=5)
    print(results)

    # Evaluate video for knowledge base
    evaluation = await evaluate_video_for_knowledge_base("dQw4w9WgXcQ")
    print(evaluation)

Environment Variables Setup

You can also use environment variables instead of the credentials file:

export YOUTUBE_API_KEY="your_api_key_here"

📖 Usage Examples

Basic Video Information

# Get detailed video information
result = await get_video_details("https://www.youtube.com/watch?v=dQw4w9WgXcQ")

# Also works with video IDs
result = await get_video_details("dQw4w9WgXcQ")

Search and Discovery

# Search for recent Python tutorials
tutorials = await search_videos(
    query="Python tutorial",
    max_results=10,
    order="date"
)

# Get trending videos in the US
trending = await get_trending_videos(region_code="US", max_results=5)

Channel Analysis

# Get channel information
channel_info = await get_channel_details("@3Blue1Brown")

# Get recent videos from a channel
recent_videos = await get_channel_videos("@3Blue1Brown", max_results=5)

# Get all playlists from a channel
playlists = await get_channel_playlists("@3Blue1Brown")

Content Evaluation (Special Feature)

# Evaluate if a video is worth adding to knowledge base
# Includes technology freshness scoring for educational content
evaluation = await evaluate_video_for_knowledge_base("Z6nkEZyS9nA")

# Example output:
# 🟢 HIGHLY RECOMMENDED - Strong indicators of valuable content
# ⏰ Content Freshness: Very Recent (2 days old)
