Description
chrome-devtools is an agent skill for debugging web pages and automating the browser through the Chrome DevTools MCP server. It covers the core workflow: starting Chrome automatically on the first tool call, using a persistent Chrome profile, and reading the page structure with a snapshot that gives each element a unique ID. The agent then clicks, fills or inspects elements by that ID, and it takes a fresh snapshot when an element cannot be found because the page has changed. Page-scoped tools need a page ID, which comes from listing the open pages or from creating a new one. Extra tooling can be turned on through command-line flags when the server starts. The extension flag adds tools for working inside an extension's background service worker, and the memory flag enables memory debugging. You can see the server's options by running its help command. The skill is a companion to the CLI version of the same tools. It is published in the chromedevtools/chrome-devtools-mcp repository, which has about 53,600 stars on GitHub. The listing shows it as free, and its security audits show passes from Gen Agent Trust Hub and Socket, with a warning from Snyk.…
