MCP server for managing pfSense firewalls through AI assistants

개요

MCP server for managing through AI assistants like Claude, ChatGPT, and Copilot. : pfrest package installed on your pfSense instance (provides the REST API). - for destructive operations (delete rules, delete mappings, restart services, apply changes): the tool returns a warning on first call and only executes when called again with confirm=true. - Like the pfSense WebGUI, add_* and delete_* store the change in the config but do not activate it. The tool response says so (applied: false, plus a pending note). Activate with apply_changes(subsystem, confirm=true) — which reloads that subsystem, including anything a human left staged in the WebGUI — or pass apply=true on the write itself when you explicitly want a one-shot change. Nothing the assistant does reaches the packet filter without one of those two explicit steps. - delete_dhcp_static_mapping takes the mapping's interface (its parent_id in list_dhcp_static_mappings) and mapping_id; a mapping is addressed by both. 1.

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

20 tools across 7 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
Pending changes	`get_pending_changes`, `apply_changes`	See what is staged per subsystem (firewall, dhcp, dns) and apply it
Monitoring	`get_gateway_status`, `get_arp_table`, `list_services`, `get_firewall_logs`	Gateway health, connected devices, service status, recent raw firewall log entries
Services	`restart_service`	Restart any pfSense service

Safety

Two-step confirmation for destructive operations (delete rules, delete mappings, restart services, apply changes): the tool returns a warning on first call and only executes when called again with confirm=true.
Writes are staged, not live. Like the pfSense WebGUI, add_* and delete_* store the change in the config but do not activate it. The tool response says so (applied: false, plus a pending note). Activate with apply_changes(subsystem, confirm=true) — which reloads that subsystem, including anything a human left staged in the WebGUI — or pass apply=true on the write itself when you explicitly want a one-shot change. Nothing the assistant does reaches the packet filter without one of those two explicit steps.
delete_dhcp_static_mapping takes the mapping’s interface (its parent_id in list_dhcp_static_mappings) and mapping_id; a mapping is addressed by both.
