In this video, I explain Model Context Protocol (MCP) with real practical examples instead of just theory. We will use Claude Code with different MCP tools while building a full-stack e-commerce project — from planning and architecture diagrams to AI-generated visuals and finally deploying the application live.

You will see how Claude Code can connect with external tools and use their capabilities through MCP.

We will cover three practical MCP examples:

🔹 Mermaid MCP — Generate and render architecture, flow and project diagrams directly from Claude Code.

🔹 Higgsfield AI MCP — Give Claude Code access to AI image/video generation capabilities and create professional visual assets for our e-commerce website.

🔹 Hostinger MCP — Connect Claude Code with hosting infrastructure and deploy our completed application to a live domain.

Most importantly, we will understand what is actually happening behind the scenes.

Claude Code itself does not magically become Mermaid, Higgsfield AI or Hostinger.

MCP provides a standardized way for an AI application to communicate with external tools, data and workflows and use the capabilities they expose.

In this video you'll learn:

• What is MCP?
• What is Model Context Protocol?
• Why do AI applications need MCP?
• How MCP gives Claude Code access to external tools
• MCP vs doing everything manually
• How to connect an MCP server with Claude Code
• Mermaid MCP practical example
• Higgsfield AI MCP practical example
• Hostinger MCP deployment example
• MCP permissions and security
• How MCP fits into modern AI Agents and coding workflows

This tutorial is explained in simple Hindi/Hinglish with practical demonstrations.
