Practical Lesson 5 of 7

MCP, Hooks, and Tools

Claude Code has a ridiculous amount of features. Most people use 10% of what's available. If you're not experimenting, you're leaving value on the table.

MCP (Model Context Protocol)

Connect Claude to external services: Slack, GitHub, databases, APIs.

Rule of thumb: If you're constantly copy-pasting from somewhere, there's probably an MCP for it. Check marketplaces or build your own.

  • Fetch data from databases directly
  • Read/write to external services
  • Query APIs without manual copying

Hooks

Run code automatically before or after Claude makes changes.

  • Run Prettier on every file save
  • Type-check after edits
  • Lint before commits
  • Auto-format imports

Good for reducing technical debt automatically.

Custom Slash Commands

Create reusable prompts as /commands.

Add markdown files to .claude/commands/ folder. Each file becomes a slash command. Package repeated prompts:

  • /debug - Your debugging workflow
  • /review - Code review checklist
  • /deploy - Deployment preparation

The Mindset

If you're paying for Pro Max, try everything. Don't give up if something doesn't work the first time. Models improve weekly—re-test things that failed before.

The people getting the most value from Claude aren't smarter—they experiment more. Every new feature is worth trying at least once.

Key Takeaways

  • MCP connects Claude to external services
  • Hooks automate quality checks
  • Custom commands package repeated prompts
  • Experiment with features—they improve constantly
