RoxyBrowser MCP Server [Beta]

English | 中文

⚠️ BETA VERSION NOTICE

This project is currently in beta testing and active development. While we strive for stability, please exercise caution when using this tool in production environments or with critical assets. We recommend closely monitoring software and browser operations when using it with MCP clients to avoid unnecessary losses.

For more details, please refer to: RoxyBrowser Now Supports MCP — AI Can Finally Do the Work for You

Quick Start

Prerequisites

1. RoxyBrowser installed and running
2. RoxyBrowser API enabled in settings:
   • Open RoxyBrowser → API
   • Set "API Status" to "Enable"
   • Copy your API Key
   • Note the API port (default: 50000)

MCP Client Configuration

Add both RoxyBrowser OpenAPI and PlayRoxy MCP to your MCP client configuration:

Claude Desktop / VS Code / Cursor:

{
  "mcpServers": {
    "roxybrowser-openapi": {
      "command": "npx",
      "args": ["@roxybrowser/openapi@latest"],
      "env": {
        "ROXY_API_KEY": "YOUR API KEY",
        "ROXY_API_HOST": "http://127.0.0.1:50000"
      }
    },
    "roxybrowser-playwright-mcp": {
      "command": "npx",
      "args": ["@roxybrowser/playwright-mcp@latest"]
    }
  }
}

Note: Replace YOUR API KEY and YOUR API HOST with your actual RoxyBrowser credentials.

Complete Workflow Examples

Example 1: Quick Browser Automation Setup

1. AI: "Create a browser in workspace 1 with name 'Test Browser'"
   → Uses roxy_create_browser
   → Returns browser ID ready for use

2. AI: "Open the browser I just created"
   → Uses roxy_open_browsers with the returned ID
   → Returns CDP WebSocket URL like: ws://127.0.0.1:52314/devtools/browser/xxx

3. AI: "Navigate to gmail.com, login, and send emails"
   → Uses PlayRoxy MCP tools (browser_navigate, browser_type, browser_click, etc.)
   → PlayRoxy MCP connects to the opened browser via CDP endpoint

4. AI: "Close the browser when done"
   → Uses roxy_close_browsers

Example 2: Browser with Proxy

1. AI: "Detect my proxy before creating browsers"
   → Uses roxy_detect_proxy
   → Confirms proxy is available

2. AI: "Create a browser with SOCKS5 proxy and 1920x1080 in workspace 2"
   → Uses roxy_create_browser with proxy configuration
   → Returns configured browser ID

3. AI: "Open the browser and start automation"
   → Uses roxy_open_browsers → gets CDP endpoint
   → PlayRoxy MCP connects and begins automation

Integration with Playwright MCP

RoxyBrowser MCP is designed to work seamlessly with PlayRoxy MCP, our customized Playwright MCP server built specifically for RoxyBrowser compatibility.

PlayRoxy MCP is based on Microsoft's Playwright MCP with enhancements for RoxyBrowser's fingerprint browser features.

Workflow

1. Use RoxyBrowser OpenAPI MCP to create and open browsers
2. Get CDP WebSocket endpoints from opened browsers
3. Use PlayRoxy MCP to automate browser tasks with full Playwright capabilities

Both servers work together seamlessly when configured in your MCP client (see configuration above).

Development

# Development mode with auto-rebuild
npm run dev

# Build for production
npm run build

API Reference

Environment Variables

| Variable | Required | Default | Description | |----------|----------|---------|-------------| | ROXY_API_KEY | ✅ Yes | - | API key from RoxyBrowser settings | | ROXY_API_HOST | ✅ Yes | http://127.0.0.1:50000 | RoxyBrowser API endpoint | | ROXY_TIMEOUT | No | 30000 | Request timeout in milliseconds |

Troubleshooting

Connection Issues

Error: "Failed to connect to RoxyBrowser API"

Check:

1. RoxyBrowser is running
2. API is enabled: RoxyBrowser → API → API Status = Enable
3. Correct API key: Copy from RoxyBrowser → API → API Key
4. Correct port: Check RoxyBrowser → API → Port Settings (default: 50000)
5. No firewall blocking http://127.0.0.1:50000

Authentication Issues

Error: "Configuration Error: API key is required"

Set the environment variable:

export ROXY_API_KEY="your_actual_api_key_from_roxybrowser"

Browser Opening Issues

Error: "Insufficient profiles quota" (Code 101 or 409)

Solutions:

• Purchase more profiles in RoxyBrowser Billing Center
• Delete unused browser profiles using roxy_delete_browsers (closing alone does NOT free quota)
• Upgrade your subscription plan
• Check current quota usage in workspace settings

Some browsers fail to open:

• Check that the browser profiles exist and are not corrupted
• Ensure sufficient system resources (RAM, CPU)
• Verify the dirIds are valid (use roxy_list_browsers first)
• Run roxy_health_check for connectivity and health diagnostics
