Overview

From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.

Automated QA testing using Browser-Use agents.

https://github.com/user-attachments/assets/9558d051-78bc-45fd-8694-9ac80eaf9494

An MCP server that launches multiple Browser-Use agents to test a vibe-coded website for UI bugs, broken links, accessibility issues, and other technical problems.

Perfect for testing both live websites and localhost development sites.

Vibecode and vibetest until your website works.

Quick Start

# Install dependencies
uv venv
source .venv/bin/activate
uv pip install -e .

# Install the browser
playwright install chromium --with-deps --no-shell

1) Claude Code

# Add MCP server via CLI
claude mcp add vibetest /full/path/to/vibetest-use/.venv/bin/vibetest-mcp -e GOOGLE_API_KEY="your_api_key"

# Test in Claude Code
> claude

> /mcp 
⎿  MCP Server Status

• vibetest: connected

2) Cursor (manually)

  1. Install via MCP Settings UI:
  2. Open Cursor Settings
  3. Click on "MCP" in the left sidebar
  4. Click "Add Server" or the "+" button
  5. Manually edit config:
{
"mcpServers": {
"vibetest": {
"command": "/full/path/to/vibetest-use/.venv/bin/vibetest-mcp",
"env": {
"GOOGLE_API_KEY": "your_api_key"
}
}
}
}

Basic Prompts

Questions

What is the Vibetest Use MCP server?

Vibetest MCP - automated QA testing using Browser-Use agents

What tools does Vibetest Use expose?

2 in total: 0 read-only, 2 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.

Is Vibetest Use safe to connect to an agent?

The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.

What credentials does Vibetest Use need?

It reads GOOGLE_API_KEY from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.

How current is this page?

The grade is for one exact copy of the source (e013ffcc35c1), read on 2026-09-27. The repository is watched and re-audited when it changes.
