🧙♂️ An intelligent Model Context Protocol (MCP) server that guides you through creating professional Playwright test suites with best practices built in.
Playwright Wizard MCP provides a structured, step-by-step approach to building comprehensive E2E test suites. Instead of starting from scratch or copying boilerplate, this MCP server guides you through industry best practices with intelligent prompts tailored to your application.
No installation required! Use npx to run the server on-demand:
{
"mcpServers": {
"playwright-wizard": {
"command": "npx",
"args": ["-y", "playwright-wizard-mcp"]
}
}
}This approach automatically uses the latest version without managing local installations.
For faster startup and offline use:
npm install -g playwright-wizard-mcpThen configure without npx:
{
"mcpServers": {
"playwright-wizard": {
"command": "playwright-wizard-mcp"
}
}
}Also available in the official MCP Registry for easy discovery.

}Playwright Wizard exposes 15 tools organized into three categories: core workflow, optional enhancements, and reference documentation.
These 5 tools guide you through creating a complete, production-ready test suite:
| Tool | Purpose | What It Creates | When to Use |
|---|---|---|---|
| analyze-app | Analyzes your application structure and tech stack | project-config.md, pages.md, selector-strategy.md | Start here - First step for any new test suite |
| generate-test-plan | Creates comprehensive test scenarios and acceptance criteria | test-plan.md with suites, flows, and edge cases | After analyzing the app |
| setup-infrastructure | Sets up Playwright config, fixtures, and folder structure | playwright.config.ts, fixtures, test helpers | After test plan is ready |
| generate-page-objects | Generates type-safe page object models with optimal selectors | Page object files in tests/pages/ | After infrastructure is set up |
| implement-test-suite | Writes actual tests with assertions and error handling | Complete test files in tests/ | Final step - implement all planned tests |
Add these capabilities after completing the core workflow:
| Tool | Purpose | What It Adds | When to Use |
|---|---|---|---|
| setup-ci-cd | Adds GitHub Actions for automated testing | .github/workflows/playwright.yml | When you need CI/CD integration |
| add-accessibility | Integrates axe-core for WCAG 2.1 AA compliance | Accessibility test helpers and examples | For accessibility requirements |
| add-api-testing | Adds REST/GraphQL/tRPC API testing | API test utilities and examples | When testing backend APIs |
| advanced-optimization | Deep performance optimization and auth state reuse | Advanced patterns and configs | For complex apps with performance needs |
Access these anytime for additional context and patterns:
| Tool | Content | Use When |
|---|---|---|
| reference-core-principles | Core testing principles and quality standards | You need guidance on best practices |
| reference-workflow-overview | Complete workflow explanation and prompt relationships | You want to understand the big picture |
| reference-mcp-setup | MCP server setup and usage patterns | Having installation or configuration issues |
| reference-selector-strategies | Selector best practices and HTML quality scoring | Need help choosing the right selectors |
| reference-fixture-patterns | Playwright fixture patterns for parallel execution | Working with fixtures or state management |
| reference-data-storage-patterns | Test data storage patterns (ORM, JSON, MSW) | Need guidance on test data management |
Simply ask your AI assistant to use them:
"Use the analyze-app tool to help me understand my application"
"Run the generate-test-plan tool to create test scenarios"
"Use setup-infrastructure to configure Playwright"The AI will call the appropriate tool, receive detailed instructions, and execute them automatically. You'll see the results (files created, analysis completed) without seeing the internal instructions.
Here's what a typical workflow looks like:
Step 1: Analyze Your Application
You: "Help me analyze my React app for Playwright testing"
AI: *Calls analyze-app tool*
- Detects React, TypeScript, Vite from package.json
- Browses key pages (/, /login, /dashboard)
- Evaluates DOM quality and accessibility
- Creates .playwright-wizard-mcp/ folder with analysis files
AI: "✅ Analysis complete! Your app uses React + TypeScript with Vite.
I found 5 key pages. HTML quality is good (score: 8/10).
Created project-config.md, pages.md, and selector-strategy.md."Step 2: Generate Test Plan
You: "Create a test plan based on the analysis"
AI: *Calls generate-test-plan tool*
- Creates comprehensive test scenarios
- Defines user flows and edge cases
- Specifies acceptance criteria
- Adds test data requirements
AI: "✅ Test plan created! I've defined 4 test suites:
- Authentication (5 scenarios)
- Dashboard (7 scenarios)
- User Profile (4 scenarios)
- Settings (3 scenarios)
See test-plan.md for details."Step 3: Set Up Infrastructure
You: "Set up the Playwright infrastructure"
AI: *Calls setup-infrastructure tool*
- Creates playwright.config.ts with optimal settings
- Sets up fixtures for parallel execution
- Creates folder structure (tests/, pages/, fixtures/)
- Adds test helpers and utilities
AI: "✅ Infrastructure ready!
- Created playwright.config.ts (3 browsers, parallel mode)
- Set up custom fixtures for test isolation
- Organized folder structure
Ready for page objects!"Step 4: Generate Page Objects
You: "Generate page object models"
AI: *Calls generate-page-objects tool*
- Creates type-safe page objects
- Uses optimal selectors (getByRole, getByLabel)
- Adds TypeScript types
- Implements reusable methods
AI: "✅ Page objects created!
- tests/pages/LoginPage.ts
- tests/pages/DashboardPage.ts
- tests/pages/ProfilePage.ts
All use accessible selectors and TypeScript."Step 5: Implement Tests
You: "Implement the test suite"
AI: *Calls implement-test-suite tool*
- Writes complete test files
- Adds proper assertions and error handling
- Verifies parallel execution
- Optimizes performance
AI: "✅ Test suite complete!
- Created 19 tests across 4 suites
- All tests pass ✓
- Average execution: 12s (parallel)
- 100% of tests use page objects
Run: npx playwright test"The wizard creates a complete test infrastructure in your project:

analyze-app toolYou see results, not prompts. The tools provide Copilot with expert-level instructions that it follows automatically.
# In your app project, ask Copilot:
"Help me set up Playwright testing for this app"
# Copilot will:
# 1. Call analyze-app → detect stack, browse pages
# 2. Call generate-test-plan → create test scenarios
# 3. Call setup-infrastructure → create config and fixtures
# 4. Call generate-page-objects → create page models
# 5. Call implement-test-suite → write actual testsAll workflow documentation files are created in .playwright-wizard-mcp/ folder in your project root:
project-config.md - Detected tech stackpages.md - Page analysis with DOM quality scoresselector-strategy.md - Selector approach per pagetest-plan.md - Test suites with progress trackingNote: The.playwright-wizard-mcp/folder is for workflow tracking only. You may want to add it to.gitignore.
