Quest 7: Power Up Your AI Agent with MCP Server Tools
TheJS AI Build-a-thon is heating up, and Quest 7 is here to level up your AI game. If you’re a JavaScript or TypeScript dev eager to build smarter AI apps, this challenge is for you. Previously, you started with agentic development—giving AI the ability to act and reason. Now, it’s time to go deeper.
What’s New in Quest 7?
This quest introduces the Model Context Protocol (MCP), a fresh standard in agentic AI development. MCP lets your AI agents use external tools in a standardized, secure way. Instead of hardcoding every function, MCP defines tools consistently, enabling your AI to decide when and how to use them.
“You’re not just building with AI — you’re giving AI the tools to build with you.”
In practical terms, you’ll create and launch an MCP server using the official TypeScript SDK. This server connects your AI agent to real-world tools that can, for example, fetch details about your local operating system. Yes, your AI can now responsibly “snoop” your system for insights.
Major Updates: Building with MCP and AI Toolkit
Quest 7 guides you through:
- Setting up an MCP server with the MCP TypeScript SDK
- Connecting your AI agent to this server via the AI Toolkit extension in Visual Studio Code
- Testing and iterating your tool-augmented agent directly inside VS Code
The AI Toolkit extension offers a smooth playground for authoring, evaluating, and integrating MCP tools. This makes the development process seamless and interactive.
What You Need to Get Started
Before diving in, ensure you have:
- A GitHub account
- Visual Studio Code installed
- Node.js installed
- The AI Toolkit extension for VS Code
Also, it’s strongly recommended to complete Quest 6 first. It lays the foundation for creating and testing AI agents, making Quest 7 much easier to tackle.
Key Concepts to Master
During this quest, you’ll explore:
- Tool-Compatible Models: Agents that access external tools to retrieve system info.
- Model Context Protocol (MCP): A secure, structured way to extend AI abilities via external tools.
“MCP allows you to define tools through a consistent standard — and your agent figures out when and how to use them.”
Why This Matters
With MCP, AI agents gain real-world reach and flexibility. They’re no longer limited to pre-coded functions but can dynamically interact with tools. This approach aligns with emerging industry practices and sets the stage for more powerful AI applications.
