OPNsense FAQs

Question 1

What is OPNsense MCP Server?

Accepted Answer

OPNsense MCP Server is a Python application that allows you to manage your OPNsense firewall using natural language through AI clients like Claude Desktop. It acts as an intermediary, translating AI requests into OPNsense API calls.

Question 2

What key features does OPNsense MCP Server offer?

Accepted Answer

It provides full access to OPNsense API functionality, including firewall rule and alias management, network interface and system health monitoring, DHCP and service management, and basic firewall security audits. You can also execute custom API calls.

Question 3

Is it secure to manage my firewall with AI using this tool?

Accepted Answer

Yes, the Model Context Protocol (MCP) is designed for security and audibility. You maintain control over what the AI can access, and all actions are logged. It's recommended to use dedicated API users with minimal required privileges on your OPNsense firewall.

Question 4

What are the requirements to run OPNsense MCP Server?

Accepted Answer

You need Python 3.10 or higher, an OPNsense firewall with API access configured, and an MCP-compatible AI client such as Claude Desktop. Basic command-line tools like Git and `uv` are also required for installation.

Question 5

How does it enable AI to manage my OPNsense firewall?

Accepted Answer

It implements Anthropic's Model Context Protocol (MCP), a standard that lets AI models securely interact with external tools. The server translates natural language commands from the AI client into precise OPNsense API actions, enabling tasks like firewall rule creation or system monitoring.
