get_youtube_video_info
AI agents call get_youtube_video_info to retrieve information from Crawl4AI MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Retrieving publicly available YouTube video information (title, duration, description, thumbnails, etc.) is a read-only operation with no side effects, data modification, or external state changes. It fits the Read category. Severity is low as it only accesses public data without destructive or financial implications.
From the tool's definition Tool name 'get_youtube_video_info' and sibling tools like 'extract_youtube_transcript' on a web crawling/content extraction server indicate retrieval of public video metadata. Tool description is empty, lowering confidence slightly.
