AI QA Agent MCP

A TypeScript-based Model Context Protocol server that analyzes Playwright test results and provides structured QA insights.

Project Goal

This project demonstrates how an AI agent can use MCP tools to:

• Discover Playwright test-result files
• Calculate test execution metrics
• Analyze failed and flaky tests
• Group similar failures
• Generate QA execution summaries
• Create draft bug reports
• Provide release-quality recommendations

Development Commands

Install dependencies:

npm install

Run the server during development:

npm run dev

Check TypeScript:

npm run typecheck

Run automated tests:

npm test

Build the project:

npm run build

Run all validations:

npm run check

Security Principles

• Read-only report access by default
• Restricted file-system access
• Input validation for every MCP tool
• No automatic issue creation
• No secret values in logs
• Human review required for AI-generated conclusions

Current Status

Version 0.1.0 is under development.
