Chrome DevTools MCP

MCP server

submitted 2d ago by u/client to c/frontend · 0 uses

Gives your agent Chrome DevTools: performance traces, network requests, console messages and screenshots of a live page.

From the Chrome DevTools team. The agent can open your page, record a performance trace, inspect failing network calls and read console errors, then suggest fixes with evidence.

Try: "Load localhost:3000, find what's slowing down LCP and fix it."

Runs a Chrome instance on your machine.
