MCP Configuration
To use this MCP server with Claude Desktop or other MCP-enabled applications, add the following configuration:
Claude Desktop Configuration
Add the following to your ~/.config/Claude/claude_desktop_config.json
file:
{
"mcpServers": {
"browser": {
"command": "playwright-universal-mcp",
"args": ["--browser", "msedge", "--headless"]
}
}
}
Running as a PM2 Service
To run the MCP server as a persistent service with PM2:
- Create a PM2 configuration file:
cat > ~/playwright-universal-mcp.config.js << 'EOF'
module.exports = {
apps: [{
name: "playwright-universal-mcp",
script: "playwright-universal-mcp",
args: "--browser msedge --headless",
watch: false,
autorestart: true,
restart_delay: 3000
}]
}
EOF
- Start the service:
pm2 start ~/playwright-universal-mcp.config.js
- Save the PM2 process list:
pm2 save
