youtube_get_transcript
AI agents call youtube_get_transcript to retrieve information from YouTube MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

While the description is empty (lowering confidence slightly), the tool name and server context clearly indicate data retrieval rather than creation, modification, execution, or deletion. Confidence reduced from 0.90 to 0.85 due to missing description that could reveal unexpected capabilities.
