TDQS
Scored across 6 tools
Each tool targets a distinct resource or action: raw transcripts, video metadata, transcript summarization, transcript search, comments, and channel info. The three transcript tools are clearly differentiated by their verbs (get, summarize, search).
Most tools follow a get_* pattern (get_transcript, get_video_info, get_comments, get_channel_info), while summarize_transcript and search_in_transcript use action-specific verbs. This is a minor deviation but still follows a consistent verb_noun structure in snake_case.
Six tools is well-scoped for a YouTube MCP server, covering transcript handling (3 tools), video info, comments, and channel info without overloading the surface. Each tool serves a clear purpose.
The set covers core read-only video analysis workflows: metadata, transcript, comments, and channel details. Minor gaps exist, such as video search or listing videos by channel, but the apparent purpose is well-served.
