ONOS MCP Server

Overview

A Model Context Protocol (MCP) server implementation that provides network control and management capabilities through the ONOS SDN controller. This server enables AI assistants to access ONOS network management, OpenFlow device control, and comprehensive analytics through a structured API interface. The server is ideal for educational environments, network operations, SDN research, and AI-assisted network management.
