Browser Devtools Mcp

Gives Claude programmatic control over a Playwright browser instance with a reference-based interaction model. You can capture screenshots, navigate pages, and interact with elements using ARIA references instead of raw selectors. The ref-based approach means you grab an accessible element reference and pass it to click, fill, or other interaction commands. Useful when you want Claude to debug web UIs, run visual regression checks, or automate browser workflows without maintaining brittle CSS selectors. Runs over stdio or streamable HTTP, so you can host it remotely or run it locally alongside your Node.js environment.
