A powerful browser automation MCP (Model Context Protocol) server that provides persistent browser sessions with advanced automation capabilities through Playwright.

Key Differences from playwright-mcp

🔒 Persistent Data Directory

PlayWriter MCP maintains a persistent user data directory between runs. This enables:

Login sessions with Google and other OAuth providers
Website authentication that persists across sessions
Test automation without repeated logins
Preserved cookies, local storage, and browser state

🛡️ Anti-Detection Features

Built-in detection prevention mechanisms allow automation on websites with bot protection:

Works seamlessly with Google and other major platforms
User-agent rotation
Automation flag removal
Realistic browser fingerprinting

🌐 Shared Chrome Instance

Single Chrome instance shared between all agents
Each agent operates in its own tab
Can reuse existing pages/tabs via context.pages() in the execute tool
Find and switch between pages by URL or other criteria
Efficient resource usage
Better performance for multi-agent workflows

🚀 Single Powerful Execute Tool

Instead of many granular tools, PlayWriter provides one flexible execute tool:

Direct access to Playwright page and context objects
Write complex automation logic with loops and conditions
Full JavaScript execution capabilities
Custom wait conditions and complex interactions

Example:

// Complex wait logic with custom conditions
while (!(await page.isVisible('.success-message'))) {
    await page.click('.retry-button');
    await page.waitForTimeout(1000);
}

🔧 Additional Tools

new_page - Create a new browser tab/page
accessibility_snapshot - Get page structure as JSON
console_logs - Retrieve browser console messages
network_history - Monitor network requests
