# Playwright MCP Setup
This project includes Playwright MCP (Model Context Protocol) for AI-assisted browser automation.
## What is Playwright MCP?
Playwright MCP allows AI assistants (like Claude) to interact with a real browser through the Model Context Protocol. This enables:
- Automated browser testing
- Web scraping and data extraction
- Visual testing and screenshots
- Navigation and interaction with web pages
## Setup
All dependencies are already installed:
- `@playwright/mcp` - MCP server for Playwright
- `@playwright/test` - Playwright test framework
- `playwright` - Browser automation library
- Chromium browser (downloaded via `bunx playwright install`)
## Configuration
### Qwen Code MCP Config (`.qwen/settings.json`)
Qwen Code automatically loads this file on new session start:
```json
{
"mcpServers": {
"playwright": {
"command": "npx",
"args": ["@playwright/mcp@latest", "--headless"],
"timeout": 30000
}
}
}
```
### Playwright Config (`playwright.config.ts`)
Standard E2E test configuration with:
- Chromium browser
- Base URL: http://localhost:3000
- Auto-starts dev server for testing
## Usage
### Start MCP Server
```bash
bun run mcp:playwright
```
This starts the MCP server on port 3000 in headless mode. AI assistants can connect to this server to control the browser.
### Run E2E Tests
```bash
# Using Playwright's test runner
bunx playwright test
# Using the existing test suite
bun run test:e2e
```
### Install/Update Browsers
```bash
# Install all browsers
bunx playwright install
# Install specific browser
bunx playwright install chromium
```
## Integration with AI Assistants
When using an AI assistant that supports MCP:
1. Start your app: `bun run dev`
2. Start the MCP server: `bun run mcp:playwright`
3. The AI assistant can now:
- Navigate to your app
- Take screenshots
- Click elements and fill forms
- Test user flows
- Debug UI issues
## Available MCP Tools
The Playwright MCP server provides tools for:
- `browser_navigate` - Navigate to a URL
- `browser_screenshot` - Take a screenshot
- `browser_click` - Click an element
- `browser_type` - Type text into an element
- `browser_select_option` - Select dropdown options
- `browser_hover` - Hover over elements
- `browser_evaluate` - Execute JavaScript
- `browser_snapshot` - Get page accessibility snapshot
- And more...
