Chrome DevTools MCP
officialPerformance traces and network data from a live browser
What is Chrome DevTools MCP?
Built by the Chrome team, this answers a different question from Playwright. It records performance traces, lists network requests and reads console messages, turning a vague complaint about a slow page into something an agent can investigate. Free.
Requirements: Runs locally with Node.js and a Chrome installation. No credentials required.
Playwright drives a browser to do things. Chrome DevTools MCP watches a browser to explain things. Both are useful and they are not substitutes.
The practical use is performance debugging. An agent with access to real trace data can identify what is actually blocking render rather than guessing from the source.
Runs locally with no credentials.
