Claude Code Hooks + MCP Tutorial | Tavily, Notion, Substack MCP | Claude Code Full Course

Master Claude Code Hooks and MCP Integration in Lesson 3 of my Claude Code Full Course. Connect Tavily and Notion MCP servers plus Substack Custom MCP, then build deterministic hook behaviors that control how your AI system acts on files automatically. This is Lesson 3 of the Claude Code Full Course. The same content multiplier system from Lessons 1 and 2 gets a serious upgrade here. By the end, your AI system will access real-time web data, tap into your Notion workspace, and enforce quality rules automatically through hooks. 🎯 What You'll Learn • What MCP (Model Context Protocol) is and how it bridges AI to external data sources • How to set up Tavily MCP for real-time web search inside Claude Code • How to authenticate and configure Notion MCP for content and knowledge management • What Claude Code Hooks are and why they differ from skills and agents (hooks are guaranteed, not probabilistic) • All 29 hook events and when to use pre-tool vs post-tool use • How to build a hook that auto-formats content every time a file is edited • How to protect sensitive folders from accidental AI modifications • How to enforce consistent, automated behaviors across your full AI workflow 🛠 Tools Covered • Claude Code (Anthropic) • Tavily MCP: real-time web search API • Notion MCP: content and knowledge base management • JQ: command-line JSON processor used in hook scripts 📋 Prerequisites • Lessons 1 and 2 recommended for content multiplier system context • Claude Code installed and configured on your machine • Tavily account (free tier available) • Notion account (optional, required only for the Notion MCP section) ⚡ Key Insight From This Lesson Hooks are the most underused feature in Claude Code. Unlike skills or agents, which are probabilistic, hooks fire deterministically every single time. They are the foundation of any reliable, production-grade AI system. In this lesson you build two hooks from scratch and learn exactly when to use each of the 29 hook events. This is part of a full Claude Code series focused on building real content automation systems, not toy demos. 📺 CHAPTERS: 0:00 Introduction and Series Recap 2:07 What is MCP 5:10 Setting Up Tavily MCP in Claude Code 9:13 Testing Tavily Connection 11:15 Connecting Claude Code Notion MCP 15:33 Token Optimization and MCP Overview 19:46 Introduction to Claude Code Hooks 22:53 Claude Code Hook Lifecycle Explained 26:59 Building Your First Hook 32:14 Folder Protection Hook 40:24 Wrap Up and Key Takeaways 📥 Helpful Links: 🛠️ Check my AI Systems store → https://store.genaiunplugged.com/ ▶️ Watch the Full n8n Zero to Hero Course Playlist → https://tinyurl.com/3rw3x6hy 🌐 Subscribe to GenAI Unplugged Substack → https://genaiunplugged.substack.com/ 🤝 Let's connect on LinkedIn → https://www.linkedin.com/in/dheerajsharma14/ 📚 Browse all my courses → https://genaiunplugged.com/ 🙌 Like this video?
