MCP server running parallel browser agents for automated website QA testing

From the Xiry library · Updated 10 October 2026

Visit github.com ↗

vibetest-use is an MCP server that uses Browser-Use and Playwright to launch multiple AI agents that crawl local or live websites. It identifies UI bugs, 404 errors, dead links, and accessibility issues directly inside AI coding tools like Claude Code and Cursor. This enables developers to run an automated test-fix-retest cycle without leaving their coding assistant.

What it's for

  • Run automated browser QA tests on localhost development servers
  • Detect broken links, 404s, and dead buttons across a website
  • Verify visual fixes and regressions directly through Claude Code or Cursor

Features

  • Model Context Protocol (MCP) server integration for Cursor and Claude Code
  • Multi-agent parallel testing with configurable agent counts
  • Supports both headless and visible browser testing via Playwright Chromium
  • Works on both localhost environments and public live websites
  • Powered by Gemini 2.0 Flash for automated browser navigation

Pricing

Open source. Free and open-source (requires user's Google Gemini API key)
