I Didn't Get MCP, So I Built My Way Through It

MCP is everywhere in AI tooling, but what actually is it? This talk follows one developer's honest journey: not understanding MCP, deciding to build an inspector to figure it out, and discovering something much bigger along the way. We'll walk through building a Ruby MCP inspector gem from scratch using Rails 8. Then comes the plot twist — what if your Rails app could read available MCP servers and generate its own UI dynamically? Add a new server, get a new interface. No redeploy.
