Why this server?
Provides tools for managing OPNsense firewall operations, including ARP, DHCP, logs, rules, interfaces, system status, and packet capture.
AlicenseBqualityBmaintenanceOPNsense firewall operations via API & mcp. Query ARP, DHCP, firewall rules, logs, interfaces, system status, and packet capture via STDIO or SSE.1412MITWhy this server?
Provides comprehensive firewall operations for OPNsense appliances: reading firmware, health, interfaces, gateways, rules, NAT, aliases, VPN (WireGuard/OpenVPN/IPsec), DHCP, and firewall logs, plus governed writes such as toggling rules, editing aliases, restarting services, applying staged changes, and rebooting.
AlicenseAqualityBmaintenanceGoverned OPNsense + pfSense firewall operations — gateway-health, rule-shadow, and blocked-traffic RCA, with guarded rule/alias writes, unbypassable audit logging (MCP + CLI), budget/runaway guards, dry-run, and undo/rollback.351MITWhy this server?
Provides bounded access to OPNsense using a URL and API key/secret for exact-object reads, with writes enabled only when explicitly turned on.
AlicenseAqualityBmaintenanceProvides a secure, job-oriented MCP connector for NetBox device lookup, enabling retrieval of device identity, status, site, role, and primary IP by name or ID without write access or bulk enumeration.5Apache 2.0Why this server?
Provides tools to manage firewall rules, view network interfaces, manage DHCP leases, and monitor system status on an OPNsense firewall.
AlicenseAqualityDmaintenanceEnables interaction with OPNsense firewalls through MCP tools for managing firewall rules, interfaces, DHCP leases, and system monitoring.26MITWhy this server?
Provides a safety-first MCP server for OPNsense firewalls, with read-only tools for firewall rules and aliases, interfaces, services, ARP and routing tables, firewall states and logs, system information/resources, Suricata status, and DHCP leases. It also supports policy-checked planning and applying of firewall rule and alias changes, including diffs, human approval, verification, automatic revert, rollback, and a hash-chained audit log.
AlicenseBqualityBmaintenanceEnables AI clients to inspect OPNsense 26.7+ firewall state and, with policy and a separate write-capable API user, plan, approve, apply, verify, and automatically revert firewall rule and alias changes under hash-chained auditing.2148 PyPI1MITWhy this server?
Provides tools for interacting with the OPNsense firewall API, covering all core and plugin endpoints (searchable/describable index of ~2469 endpoints and 169 models). Supports generic API calls, model CRUD operations on any controller (search, get, add, set, delete, toggle, then apply), reading and writing a whole settings model, and curated tools for a system overview, service management, neighbor discovery, firewall log inspection, and ping. Writes are disabled unless explicitly enabled.
AlicenseAqualityBmaintenanceEnables agents to search and call the full OPNsense core and plugin API, perform model-validated CRUD and settings operations, and use curated firewall, service, and network tools with optional auto-revert writes.14BSD 2-Clause "Simplified"Why this server?
