A browser automation tool based on the MCP protocol, allowing AI applications to control your browser.

Browser MCP Project Detailed Introduction

Project Overview

Browser MCP is a browser automation tool based on the Model Context Provider (MCP) protocol. It consists of an MCP server and a Chrome browser extension, allowing AI applications (such as VS Code, Claude, Cursor, and Windsurf) to control and automate user browser operations.

Project Address: https://github.com/BrowserMCP/mcp

Core Features

⚡ Fast Execution

• Local Execution: Automated operations are executed on the local machine, eliminating network latency.
• High Performance: Directly operates the user's browser, avoiding the overhead of creating new browser instances.

🔒 Privacy Protection

• Local Processing: All browser activity is processed on the local device.
• Data Security: No browser activity data is sent to remote servers.
• User Control: Users have complete control over their data and privacy.

👤 Maintain Login Status

• Existing Profiles: Uses the user's existing browser profile.
• Session Persistence: Maintains the user's login status across various services.
• No Re-authentication: Avoids the hassle of repeated logins.

🥷 Strong Concealment

• Real Fingerprints: Uses real browser fingerprints.
• Anti-Detection: Effectively avoids basic bot detection mechanisms.
• Bypass CAPTCHA: Reduces the likelihood of encountering CAPTCHA verification.

Technical Architecture

Component Composition

1. MCP Server: Responsible for receiving and processing instructions from AI applications.
2. Chrome Extension: Executes specific automation operations in the browser.
3. Communication Bridge: The MCP protocol ensures reliable communication between the server and the extension.

Working Principle

AI -> MCP -> Browser MCP -> Chrome

Supported AI Applications

Browser MCP can be integrated with the following AI applications:

• VS Code: Integrated through the MCP extension.
• Claude: Supports browser automation commands.
• Cursor: AI code editor integration.
• Windsurf: Development environment integration.

Comparison with Other Solutions

Traditional Playwright Solution

• Playwright MCP: Creates a new browser instance.
• Browser MCP: Directly uses the user's existing browser.

Advantage Comparison

Avoid Bot Detection	✅	❌
Local Privacy Protection	✅	❌
Fast Execution	✅	❌

Technical Implementation

Based on Playwright MCP

Browser MCP is based on Microsoft's Playwright MCP server with improvements and adaptations, mainly including:

1. Execution Environment: Changed from creating a new browser instance to controlling an existing browser.
2. Session Management: Utilizes the user's existing login sessions.
3. Detection Evasion: Avoids automation detection through a real browser environment.

Development Status

• The current repository contains all core MCP code.
• Currently, it cannot be built independently due to its dependency on tools and types in the development monorepo.
• The project is under continuous development and improvement.

Application Scenarios

Development Automation

• Web Testing: Automate web functionality testing.
• Data Scraping: Intelligent web data extraction.
• Form Filling: Automate form operations.

Daily Office Work

• Repetitive Tasks: Automate repetitive browser operations.
• Information Collection: Intelligent information gathering and organization.
• Cross-Platform Operations: Unified management of multiple website operations.

AI-Assisted Work

• Intelligent Browsing: AI assistant performs browser tasks on behalf of the user.
• Context Awareness: Provides intelligent suggestions based on the current browser state.
• Workflow Integration: Integrates browser operations into AI workflows.

Installation and Usage

Prerequisites

• Chrome browser
• AI applications that support MCP (such as VS Code, Claude, etc.)
• Node.js environment (for running the MCP server)

Installation Steps

1. Install the Browser MCP extension from the Chrome Web Store.
2. Configure the MCP server.
3. Add the Browser MCP server to the supported AI application.
4. Start using the browser automation features.

Summary

Browser MCP is an innovative browser automation solution that cleverly combines the standardized advantages of the MCP protocol with the authenticity advantages of local browsers. By allowing AI applications to directly control the user's real browser environment, it not only provides better performance and privacy protection but also effectively avoids the detection problems faced by traditional automation tools. For developers and users who need browser automation, this is an excellent tool worth paying attention to and trying.
