TL;DR
browser-tools-mcpBrowser Automation · ★ 7.3k
When to choose:
- You use Cursor or a similar IDE agent and want it to read console logs, network activity, screenshots and the currently selected DOM element from your own Chrome.
- You want Lighthouse-based audits for accessibility, performance, SEO and best practices from within the agent.
- You want browser logs kept local: the README says logs are stored on your machine and never sent to a third-party service.
When to skip:
- You want the agent to click through and drive pages; this tool is aimed at monitoring and auditing, not full automation.
- You do not want to install a Chrome extension and run a separate local Node server alongside the MCP server.
- You want the most actively developed option: the latest release in the data we checked was v2.0.2 on 2026-08-12.
