Your AI Doesn't Need Screenshots. It Needs DevTools.

Your AI Doesn't Need Screenshots. It Needs DevTools. Most AI coding agents are still debugging web apps in the dumbest possible way. They ask for a screenshot. Meanwhile the real answer is usually sitting in the browser console, the Network tab, the request payload, or the response body. That is not really an AI problem. It is a tooling problem. I got tired of watching agents guess from screenshots while I had DevTools open right next to them, showing the exact reason something failed. So I built mare-browser-mcp, a browser MCP designed less like "remote control for a webpage" and more like "give the model the same debugging signals I actually use." That changed the loop from this: AI writes code -> I test it -> I describe the bug -> AI guesses a fix -> repeat to this: AI writes code -> AI tests it -> AI reads the failure -> AI fixes it That difference matters more than people think. The Screenshot Trap Most browser MCPs start from the same assumption: if the model
