Browser-use-MCP-Server MCP Server: Seamless Integration of AI Applications Through Model Context Protocol

Overview: What is Browser-use-MCP-Server?

Browser-use-MCP-Server is an advanced MCP server designed to empower AI applications, such as Claude Desktop, Continue, Cursor, and others, to control web browsers through a standardized protocol. This server leverages the versatile browser-control framework from browser-use and integrates with Model Context Protocol (MCP) clients for seamless communication between AI applications and web browsers. By adopting MCP, developers can ensure compatibility across various AI tools while maintaining robust performance.

🔧 Core Features & MCP Capabilities

Browser-use-MCP-Server offers a range of powerful features tailored to meet the demands of AI application development:

1. Dual Transport Protocols: Supports both Server-Sent Events (SSE) and stdio modes, enabling clients to communicate flexibly based on their requirements.

2. VNC Streaming: Provides real-time visualization of browser actions for debugging and monitoring purposes, ensuring transparency in complex operations.

3. Async Tasks Execution: Allows asynchronous execution of tasks within web browsers, improving efficiency and responsiveness during AI-driven interactions.

4. Envoy Compatibility: Integrates seamlessly with mcp-proxy, facilitating stdio mode communication between the server and clients.

5. Customizable Environments: Enables users to define custom environments through .env files for setting up specific configurations like API keys and browser paths.

⚙️ MCP Architecture & Protocol Implementation

The architecture of Browser-use-MCP-Server is meticulously designed to align with MCP standards, ensuring robust and scalable integration with various AI clients. The core protocol flow diagram outlines the communication process between an AI application, a server, and data sources/tools:

    style C fill:#f3e5f5
    style D fill:#e8f5e8

This protocol flow demonstrates how data and instructions are transmitted from an AI application to a web browser, facilitated by the MCP server. Key components include:

• MCP Client: The client-side software that interacts with the protocol.
• MCP Protocol: The standardized communication method used for interaction.
• MCP Server: The central server that facilitates communication between clients and data sources/tools.

🚀 Getting Started with Installation

To get started, follow these steps to install the necessary dependencies and set up your environment:

1. Prerequisites:

   • Install uv for package management.
   • Install Python packages such as Playwright for browser automation.

2. Environment Variables Setup:

   echo "OPENAI_API_KEY=your-api-key" > .env
   echo "CHROME_PATH=optional/path/to/chrome" >> .env
   echo "PATIENT=false" >> .env  # Set to true for waiting on API calls
   

3. Install Dependencies:

   uv sync
   uv pip install playwright
   uv run playwright install --with-deps --no-shell chromium
   

4. Run the Server:

   • For SSE mode:

     uv run server --port 8000
     

   • For stdio mode:

     uv build
     uv tool uninstall browser-use-mcp-server 2>/dev/null || true
     uv tool install dist/browser_use_mcp_server-*.whl
     
     # 2. Run with stdio transport
     browser-use-mcp-server run server --port 8000 --stdio --proxy-port 9000
     

Client Configuration Examples

1. SSE Mode Client Configuration:

   {
     "mcpServers": {
       "browser-use-mcp-server": {
         "url": "http://localhost:8000/sse"
       }
     }
   }
   

2. stdio Mode Client Configuration:

   {
     "mcpServers": {
       "browser-server": {
         "command": "browser-use-mcp-server",
         "args": [
           "run",
           "server",
           "--port",
           "8000",
           "--stdio",
           "--proxy-port",
           "9000"
         ],
         "env": {
           "OPENAI_API_KEY": "your-api-key"
         }
       }
     }
   }
   

3. Config Paths Across Different Clients:

   • Cursor: ./.cursor/mcp.json
   • Windsurf: ~/.codeium/windsurf/mcp_config.json
   • Claude (Mac): ~/Library/Application Support/Claude/claude_desktop_config.json
   • Claude (Windows): %APPDATA%\Claude\claude_desktop_config.json

💡 Key Use Cases in AI Workflows

Use Case 1: Real-Time Browser Automation with Claude Desktop

When integrating with Claude Desktop, users can request complex web interactions, such as navigating to a specific URL and extracting data. Below is an example of how this might work:

As Claude, open https://news.ycombinator.com and provide the top-ranked article.

This command utilizes the Browser-use-MCP-Server to trigger actions in Claude Desktop, ensuring accurate and efficient execution.

Use Case 2: Asynchronous Task Execution with Continue

For tasks requiring background processing, Continue can leverage the async capabilities of Browser-use-MCP-Server. For example:

Log into your email client at https://mail.google.com/, check for unread messages, and mark them as read asynchronously.

This operation would initiate a browser session via the MCP server, perform necessary actions, and return to an idle state until all tasks are completed.
