+#### Unix Domain Socket Mode
+
+Run the server on a Unix socket for integration with other tools:
+
+```bash
+# Start server on Unix socket
+julia --project -m LLMBenchMCPServer MyBenchmark --socket /tmp/mcp.sock
+
+# The server will listen on the socket for MCP protocol connections
+# Multiple clients can connect simultaneously
+```

 #### Programmatic Usage
