A Python [Model Context Protocol](https://modelcontextprotocol.io/) server that exposes the OPNsense REST API to AI clients such as Claude Desktop and Claude Code.

## What it does

The server proxies 43 OPNsense API endpoints across eight domains as MCP tools, letting AI clients query and mutate firewall state through natural language.

| Domain | Tools | Capabilities |
|--------|-------|--------------|
| System | 3 | Status, firmware check, config backup |
| Firewall | 17 | Rule and alias CRUD, NAT port forwards, apply |
| Interfaces | 4 | Interface list, config, ARP/NDP tables |
| DHCP | 3 | Lease list, settings, static mappings |
| Routes | 5 | Static route CRUD and apply |
| DNS | 6 | Unbound settings and host override CRUD |
| IDS | 1 | Ruleset list |
| Services | 4 | Start/stop/restart/status for core modules |

Mutating operations follow OPNsense's staged-then-apply model: changes are staged by `_add`/`_update`/`_delete` tools and committed by the corresponding `_apply` tool.

## Requirements

- Python 3.12+
- [`uv`](https://docs.astral.sh/uv/)
- OPNsense **26.1+** with API access enabled

> **Compatibility**: Tested against OPNsense 26.1.10. The 26.x release series
> made breaking REST API changes — Kea replaced ISC DHCPv4 (`kea/*` paths),
> port-forward NAT moved to Destination NAT (`firewall/d_nat/*`), and the system
> status endpoint changed. Older releases are not supported.
