A Model Context Protocol (MCP) server for comprehensive OPNsense firewall management. This server enables AI assistants like Claude to directly manage firewall configurations, diagnose network issues, and automate complex networking tasks. It exposes MCP tools across firewall, NAT, network diagnostics, SSH/CLI execution, and additional capabilities such as VLAN management, DHCP lease viewing, DNS blocklists, and HAProxy support. NAT operations are SSH-based to support outbound NAT rule management and various NAT modes with automated DMZ resolution and XML config manipulation. The server provides routing diagnostics, ARP inspection with vendor IDs, interface configuration handling, and auto-fix capabilities. It also supports executing OPNsense CLI commands, manipulating configuration files, and managing services. The project emphasizes IaC readiness, configuration backups/restores, and workload automation. The MCP server is designed to be used with Claude Desktop or other LLM-driven automation pipelines to streamline firewall administration and troubleshooting.
