Do You Actually Need an MCP Server? (Tested With Claude Code)

You already have REST APIs. Claude Code can already call them. So why is everyone suddenly building MCP servers? In this video I build a tiny order service with a normal REST API, connect Claude Code to it directly, and then build an MCP server on top of the exact same service, so you can see, side by side, what MCP actually changes and what it doesn't. What you'll learn: - Why Claude Code can already call your REST APIs directly (and when that's enough) - What breaks when an agent needs to ta
