Last Updated: October 12, 2026

🤖 AI Snapshot / TL;DR: The invisible_playwright_mcp is a production-ready, open-source Model Context Protocol (MCP) server that enables AI agents (like Claude Desktop, Cursor, and Claude Code) to securely interact with browser systems. It features local execution, standardized tool definitions, and is actively maintained with ⭐ 2,758 GitHub stars.

🔍 What is invisible_playwright_mcp?

Playwright mcp server undetected by anti-bots and captchas: ai agent browses the web on anti-detect stealth firefox, python, undetected browser automation, scraping, computer use.. By bridging the gap between large language models and your local or remote browser environment, it allows you to automate complex workflows using natural language prompts. Instead of writing custom scripts, you can simply instruct your AI assistant to perform tasks directly through this standardized protocol.

✨ Key Features

• --openrouter-key your key, or the openrouter_api_key variable.**
• --model an openrouter model id, or invisible_mcp_model. defaults to z-ai/glm-5.3-flash.**
• --proxy optional. http://user:pass@proxy.example.com:8080 or**
• --binary an engine binary you already have. it must be the build the seal**
• --seed an integer. same seed, same browser identity, every run.**

🎯 Real-World Use Cases for invisible_playwright_mcp

• Competitor Price Monitoring: Automatically scrape pricing pages daily and alert you to changes.
• Automated QA Testing: Navigate complex web flows, take screenshots, and verify UI elements without writing custom scripts.
• Data Extraction for RAG: Crawl documentation sites or blogs and convert them into clean Markdown for AI knowledge bases.
• Lead Generation: Extract contact information or company details from directories into structured CSV/JSON formats.

⚙️ Installation & Configuration

Prerequisites

• Node.js (v18+) or Python (v3.10+) installed locally.
• Claude Desktop, Cursor, or another MCP-compatible client.

Step 1: Install the Server

```bash

Recommended: Run directly via npx (no global install needed)

npx -y feder-cr/invisible_playwright_mcp

Alternative: Clone and run locally

git clone https://github.com/feder-cr/invisible_playwright_mcp.git cd invisible_playwright_mcp npm install # or pip install -r requirements.txt ```

Step 2: Update Your MCP Config

Add the following to your claude_desktop_config.json (Mac: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\) or .cursor/mcp.json:

```json { "mcpServers": { "invisible-playwright-mcp": { "command": "npx", "args": ["-y", "feder-cr/invisible_playwright_mcp"] } } } ``` (Note: Restart your AI client after saving the configuration file.)

⚙️ Advanced Configuration Options

For production environments, you may need to customize the server behavior. You can pass environment variables in your MCP config:

```json { "mcpServers": { "invisible_playwright_mcp": { "command": "npx", "args": ["-y", "feder-cr/invisible_playwright_mcp"], "env": { "API_KEY": "your_api_key_here", "TIMEOUT_MS": "30000" } } } } ``` Note: Always use environment variables for sensitive credentials. Never hardcode API keys directly in the JSON.

💡 Real-World Example Prompts

Once connected, try these high-value prompts in Claude or Cursor:

1. "Use invisible_playwright_mcp to extract structured data or automate a specific browser workflow."
2. "Configure the invisible_playwright_mcp MCP server to optimize for speed and reliability."
3. "Analyze the output from invisible_playwright_mcp and format it into a comprehensive Markdown report."
