CloudBrowser MCP Server

Next Generation Browser Automation Platform for AI Developers

Product Introduction

A cloud-native solution specifically designed for LLM agents, providing anti-association fingerprint browser environments and automated interaction APIs. No need to deploy local environments, eliminating performance bottlenecks and operational burdens, allowing developers to focus on core logic development.

Core Capabilities

▷ Anti-association Cloud Environment: Multi-environment independent fingerprint isolation, supports stealth automation operations
▷ Browser Behavior Simulation: Precise execution of web access, element-level screenshots, dynamic data capture, intelligent form filling and other interactions
▷ LLM-specific Adaptation: Browser behavior trajectory simulation, DOM tree parsing optimization, structured data output
▷ Elastic Resource Scheduling: From single session debugging to large-scale concurrent collection, automatically matches computing needs

Typical Scenarios

▷ AI Agent Training: Browser operation behavior data generation
▷ Multi-source Data Collection: Supports JS dynamic rendering and anti-crawling strategy penetration
▷ Automated Testing: Visual element operations and process recording/playback
▷ Model Fine-tuning: Real-time web data cleaning and structured output

Anti-association Cloud Environment: Multi-environment independent fingerprint isolation, supports stealth automation operations
Simplify complex human-machine interaction scenarios into API calls, reducing 90% of browser environment adaptation costs, increasing data collection success rate to 99.9%+.

Register and Create Cloud Environment Key

Before using the platform, you need to register and create a cloud environment to obtain the cloud environment API Key, which allows you to call MCP services through API to execute tasks in the cloud environment.

Register Cloud Account

Visit the official website of the cloud fingerprint browser. If you haven't registered an account yet, you need to complete user registration first.

Obtain Cloud Environment API Key

Create and obtain the cloud environment API Key in the Cloud Login Management Center.

Copy the string between "APIKEY=" and "&sessionId" in the API Key content.

Installation and Deployment

Clients can access MCP services through Node.js I/O mode. The specific steps are as follows:

Install Node.js
Download the Node application suitable for your operating system, ensuring the local Node.js version is v22.14.0 or higher.
After installation, use the node -v command in the command line to check if the installation was successful. If the check fails, try restarting your computer and checking again.

Download MCP Server Source Files
Download the MCP Server source files from https://github.com/clpublic/mcp-server-cloudbrowser.
Open the command line tool, use the cd command to switch to the source code directory, then execute cd cloudbrowser.
Execute the npm i command to install dependencies. If this command cannot be executed, first use the cd command to switch to the installation directory, then execute npm i.
Finally, execute the npm run build command to package the service files.

Install Cursor
 It is recommended to use the latest version of the Cursor client
 Log in to your Cursor account to use the large model functionality

Enter the Cursor settings interface to configure MCP Server

Add a new MCP Server configuration

{
    "mcpServers": {
        "cloudbrowser": {
            "command": "node",
            "args": [
                "path_to_your_downloaded_files/mcp-server-cloudbrowser-main/cloudbrowser/dist/index.js"
            ],
            "env": {
                "API_KEY": "your_cloud_environment_API_Key"
            },
            "transportType": "stdio"
        }
    }
}

Return to the Cursor settings interface to check the MCP service tool status

As shown above, the MCP Server - Cloudbrowser tool status is normal and available

Note:
When a "Client closed" exception occurs, you can click the "Enabled" button to solve the problem, as shown below:

Select to configure the Cursor large model for a better service experience

Model Interaction Mode: Select Agent mode
Press CTRL/CMD + L shortcut key to open the dialog box on the right side of the editor

Start Using
Example: Open Baidu website and search for "Cloud Login Browser"
