Score Breakdown
⚙ Agent Friendliness
🔒 Security
Firewall API. Use read-only credentials. HTTPS required. Network security changes need human approval. API key is sensitive.
⚡ Reliability
Best When
A network administrator using OPNsense wants AI agents to assist with firewall management — querying rules, monitoring health, and analyzing traffic patterns in AI-assisted network operations.
Avoid When
You use pfSense, Palo Alto, or other firewalls. NEVER allow agents to autonomously modify firewall rules — always require human approval for security policy changes.
Use Cases
- • Querying firewall rules and network configuration from network management agents
- • Monitoring OPNsense system health and traffic from network operations agents
- • Analyzing security logs and alerts from SOC automation agents
- • Managing network interfaces and routing from infrastructure agents
Not For
- • Teams not using OPNsense (pfSense or commercial firewall users)
- • Automated firewall rule changes without human approval (network security risk)
- • Production network changes without change management process
Interface
Authentication
OPNsense API key required — generate in OPNsense System > Access > Users. Use least-privilege API key with read-only access for agents.
Pricing
OPNsense is free open source (BSD license). MCP server is free community tool.
Agent Metadata
Known Gotchas
- ⚠ CRITICAL: Firewall rule changes affect network security — never allow autonomous agent modifications
- ⚠ Use read-only API key for agent queries — never give agents write access to firewall rules
- ⚠ OPNsense API requires HTTPS — verify TLS certificate configuration
- ⚠ Community tool — test against your OPNsense version before deploying
