Selenix MCP Server

Connect Claude Desktop to Selenix via the Model Context Protocol. Chat with Claude to create, run, debug, and manage browser automation tests — just like using the built-in AI Assistant, but powered by Claude.

Prerequisites

• Selenix desktop app installed
• Claude Desktop installed
• Node.js 18 or later

Enable the Bridge in Selenix

Before using any setup method below, enable the bridge inside Selenix:

1. Open Selenix
2. Go to System Settings (gear icon in the sidebar)
3. Scroll to the MCP Server section
4. Set Enable MCP Server to Yes

This starts a local bridge server that the MCP server connects to.

Setup

Choose one of the following methods:

Option A: Install via npm (recommended)

npm install -g @selenix/mcp-server

Then find your global npm path:

npm root -g

Open your Claude Desktop config file:

• Windows: Press Win+R, paste %APPDATA%\Claude\claude_desktop_config.json, press Enter
• macOS: Open ~/Library/Application Support/Claude/claude_desktop_config.json

Add the Selenix MCP server, replacing the path with the output from npm root -g:

{
  "mcpServers": {
    "selenix": {
      "command": "node",
      "args": ["<npm-root-path>/@selenix/mcp-server/dist/bundle.js"]
    }
  }
}

Example (Windows with nvm):

{
  "mcpServers": {
    "selenix": {
      "command": "node",
      "args": ["C:/Users/YourName/AppData/Local/nvm/v18.20.8/node_modules/@selenix/mcp-server/dist/bundle.js"]
    }
  }
}

Example (macOS/Linux):

{
  "mcpServers": {
    "selenix": {
      "command": "node",
      "args": ["/usr/local/lib/node_modules/@selenix/mcp-server/dist/bundle.js"]
    }
  }
}

If you already have other MCP servers configured, add "selenix" alongside them inside the existing "mcpServers" object.

Option B: Use the bundled version (no npm required)

If you installed Selenix as a desktop app, the MCP server is already bundled. No need to install anything — just point Claude Desktop to the bundled file.

Find your Selenix install folder and look for resources/mcp-server/index.js, then add to your Claude Desktop config:

{
  "mcpServers": {
    "selenix": {
      "command": "node",
      "args": ["C:/path/to/Selenix/resources/mcp-server/index.js"]
    }
  }
}

Typical Windows path:

C:/Users/YourName/AppData/Local/Programs/Selenix/resources/mcp-server/index.js

Option C: Manual download

1. Download bundle.js from the npm package page or from the releases page
2. Save it somewhere on your machine (e.g., C:/selenix-mcp/bundle.js)
3. Add to your Claude Desktop config:

{
  "mcpServers": {
    "selenix": {
      "command": "node",
      "args": ["C:/selenix-mcp/bundle.js"]
    }
  }
}

Node.js is still required — the MCP server is a single JavaScript file with no other dependencies.

Verify

Restart Claude Desktop after editing the config. You should see the Selenix tools icon (hammer) in the chat input area.

Try asking Claude:

• "What tests are in my Selenix project?"
• "Create a test that opens google.com and searches for 'selenium automation'"
• "Run the current test and fix any failures"
• "Take a screenshot of the browser"

How It Works

Claude Desktop <--stdio--> MCP Server <--HTTP--> Bridge Server (inside Selenix)

The MCP server translates Claude's tool calls into HTTP requests to a bridge server running inside Sele
