通过 AI 助手管理 pfSense 防火墙，支持规则、DHCP、DNS 等配置与运维操作。

README

mcp-pfsense

MCP server for managing pfSense firewalls through AI assistants like Claude, ChatGPT, and Copilot.

Requires: pfrest package installed on your pfSense instance (provides the REST API).

Features

17 tools across 6 categories:

Category	Tools	Description
System	`get_system_status`, `get_interfaces`	Version, CPU, memory, uptime, temperature, network interfaces
Firewall	`list_firewall_rules`, `add_firewall_rule`, `delete_firewall_rule`, `list_firewall_aliases`	Rule management with interface filtering, alias listing
DHCP	`list_dhcp_leases`, `list_dhcp_static_mappings`, `add_dhcp_static_mapping`, `delete_dhcp_static_mapping`	Active leases, IP reservations
DNS	`list_dns_host_overrides`, `add_dns_host_override`, `delete_dns_host_override`	Unbound DNS Resolver host overrides
Monitoring	`get_gateway_status`, `get_arp_table`, `list_services`	Gateway health, connected devices, service status
Services	`restart_service`	Restart any pfSense service

Safety

All destructive operations (delete rules, delete mappings, restart services) require two-step confirmation — the tool returns a warning on first call and only executes when called again with confirm=true.

Installation

bash

# Using uvx (recommended)
uvx mcp-pfsense

# Using pip
pip install mcp-pfsense

Prerequisites

pfSense with pfrest package installed
A user account with API access (typically admin)

Configuration

Set environment variables:

Variable	Required	Default	Description
`PFSENSE_HOST`	Yes	—	pfSense hostname or IP
`PFSENSE_PASSWORD`	Yes	—	API user password
`PFSENSE_USERNAME`	No	`admin`	API username
`PFSENSE_PORT`	No	`443`	API port
`PFSENSE_SCHEME`	No	`https`	`http` or `https`
`PFSENSE_VERIFY_SSL`	No	`false`	Verify SSL certificate

Claude Desktop

Add to claude_desktop_config.json:

json

{
  "mcpServers": {
    "pfsense": {
      "command": "uvx",
      "args": ["mcp-pfsense"],
      "env": {
        "PFSENSE_HOST": "10.10.10.1",
        "PFSENSE_PASSWORD": "your-password"
      }
    }
  }
}

Claude Code

bash

claude mcp add pfsense -- uvx mcp-pfsense

Then set environment variables in your shell or .env file.

Usage Examples

Once connected, ask your AI assistant:

"What's the pfSense system status?"
"Show me all firewall rules on the LAN interface"
"List active DHCP leases"
"Add a DNS entry for nas.home.lan pointing to 10.10.10.50"
"What devices are connected to the network?" (ARP table)
"Show gateway health and latency"
"Create a firewall rule to allow TCP port 8080 on LAN"
"Reserve IP 10.10.10.60 for MAC aa:bb:cc:dd:ee:20"

API Compatibility

pfSense: 2.7.x (tested on 2.7.2)
pfrest: v2.x (REST API v2)
Python: 3.11+

Note: pfrest runs on nginx (port 80 by default), separate from the pfSense WebGUI (lighttpd on port 443). If your pfrest is configured on a non-standard port, set PFSENSE_PORT and PFSENSE_SCHEME accordingly.
