Chrome DevTools Protocol + Claude Code: The Pattern Open Source Teams Spent Years On

I'll admit it, curiosity is both a flaw and a feature with me. Every app you use daily can do than what they show you. There's often beta features hidden behind a flag, undocumented endpoints, running, responding quietly. I pointed Claude Code at a local Ghost instance with Chrome DevTools as an MCP server. In one afternoon, the agent found 27 endpoints the official documentation mentions nowhere. Detailed member stats, a full audit log, a database export in a single call. All of that was there. From the start.
