I wanted to build a simple price comparison tool. What I ended up with made me rethink how AI agents interact with the real world.

Every AI assistant I tried had the same blind spot. Ask it "what is the cheapest iPhone 17 in Singapore right now?" and it would hallucinate a price or tell you to check Amazon.

I wanted an AI that could actually look at real prices across real stores and give me a straight answer.

What is an MCP Server?

Model Context Protocol (MCP) lets AI models call external tools. Think of it as a USB port for AI. Plug in an MCP server, and suddenly your AI can search databases, query APIs, and interact with the real world.
