YouTube Marketing Skills — YouTube growth with live channel data

content

YouTube Marketing Skills is a set of skills with an MCP server for Claude Code, Cursor, Codex, Windsurf and Gemini CLI that helps grow a YouTube channel using real data. 21 commands cover ideas, scripts, SEO for titles, descriptions and tags, Shorts, thumbnails and analytics. Ten MCP tools read the channel's private analytics through OAuth (retention, traffic sources, demographics), can write the updated title, description and tags back to YouTube and publish a companion WordPress post with VideoObject markup so the topic ranks on both Google and YouTube. The chain is /youtube-ideate, /youtube-script, /youtube-seo, then publishing. It needs Node.js 18+ and a Google Cloud project with the YouTube Data API v3 and Analytics API. License: MIT.
