Zendriver-MCP
A powerful MCP (Model Context Protocol) server for browser automation using Zendriver - an undetectable, async-first browser automation framework. Built specifically for LLM-powered automation with a focus on token efficiency.
Why Zendriver?
Most browser automation tools (Selenium, Playwright, Puppeteer) use WebDriver protocol, which is easily detected by anti-bot systems. Zendriver is different:
| Feature | WebDriver-based | Zendriver |
|---|---|---|
| Detection | Easily detected via navigator.webdriver |
Undetectable - no WebDriver flags |
| Protocol | WebDriver (standardized, detectable) | CDP (Chrome DevTools Protocol) |
| Async | Sync-first, async bolted on | Async-first architecture |
| Bot Protection | Blocked by Cloudflare, PerimeterX, etc. | Bypasses most protections |
Use cases where Zendriver is better than others:
- Automating sites with bot protection (Cloudflare, Akamai, etc.)
- Scraping dynamic SPAs that block traditional automation
- Testing authenticated workflows on protected sites
- Building AI agents that interact with the real web
Features
- Undetectable - Uses Chrome DevTools Protocol, bypassing WebDriver detection
- Token-Optimized DOM Walker - 78% reduction in token usage vs raw HTML
- 35+ Essential Tools - Focused, powerful browser automation capabilities
- Modern Web Support - Works with contenteditable divs, SPAs, and dynamic content
- Smart Element Handling - Auto-skips hidden elements, provides selector suggestions
- CDP Network Logging - Real-time network request and console log capture, its super easy to create endpoint based scrappers as llms can directly access the network logs
- Security Auditing - Comprehensive security analysis tool
Usage with Claude Desktop
Add to your claude_desktop_config.json:
{
"mcpServers": {
"zendriver": {
"command": "python",
"args": ["path/to/Zendriver-MCP/run.py"]
}
}
}
Token Optimization Protocol
The Problem
Traditional approaches send raw HTML or verbose element trees to LLMs:
The Solution
Our DOM walker produces compact, semantic output:
{"id": 1, "t": "btn", "l": "Search", "r": "hdr"}
Optimization Techniques
| Technique | Before | After | Reduction |
|---|---|---|---|
| Compact Keys | tagName, label, region |
t, l, r |
~60% |
| Smart Labels | “(unlabeled)” everywhere | Inferred from aria/text/placeholder | ~40% fewer elements |
安装
This server does not publish a one-line install command.
