Overview

What is VibeCheck Web tester?

VibeCheck Web tester is an intelligent security agent that integrates with AI coding assistants to analyze code for vulnerabilities and facilitate AI-driven remediation before insecure code reaches the codebase. It uses the Model Context Protocol (MCP) to interact with assistants like Cursor, GitHub Copilot, and Claude Code.

How to use VibeCheck Web tester?

Clone the repository, install dependencies (Python 3.10+, MCP, Playwright), configure a .env file with your LLM API key, and add the provided MCP server configuration to your AI coding assistant. Then use natural language commands to request security scans, record tests, or run regression tests.
