Vibetest Use is a Model Context Protocol (MCP) server that launches several Browser Use agents in parallel to test a website for UI bugs, broken links, accessibility problems, and other technical issues. It works against live sites and local development servers, so you can check a site as you build it from inside Claude Code or Cursor.
You register the vibetest-mcp binary as an MCP server with a Google API key, then prompt your coding assistant with a target URL, an agent count, and whether to run headless. The default is three agents in non-headless mode, and more agents cover more of the site. Agents run on gemini-2.0-flash via Playwright-installed Chromium.
Features
- Parallel agents: several Browser Use agents explore the site at once, with the count set in the prompt
- Issue types: UI bugs, broken links, accessibility issues, and other technical problems
- Target flexibility: any public URL or a local development server
- Headless option: run with visible browsers or headless
- MCP clients: Claude Code or Cursor, registered through each client's MCP settings
