Category & Scope
Tools & Capabilities Breakdown
MCP Pfsense Tools (19)
get_system_status
Get pfSense system status including version, CPU, memory, uptime, and temperature.
get_interfaces
List all network interfaces with status and configuration.
list_firewall_rules
List firewall rules, optionally filtered by interface.
add_firewall_rule
Add a firewall rule. Type is 'pass', 'block', or 'reject'.
The rule is staged (not active) until apply_changes('firewall') is called
or apply=true is passed here.
delete_firewall_rule
Delete a firewall rule by its ID (the `id` from list_firewall_rules). Requires confirm=true.
Staged until apply_changes('firewall') is called or apply=true is passed.
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
MCP Pfsense is categorized under Cloud Platforms and uses a local stdio subprocess. In contrast, Liveblocks MCP Server belongs to Cloud Platforms using local stdio subprocess. Select MCP Pfsense when you need capabilities focused on cloud platforms and Liveblocks MCP Server when you require tools for cloud platforms.
List firewall aliases (IP groups, port groups, URL lists).
list_dhcp_leases
List active DHCP leases showing IP, MAC, hostname, and lease times.
list_dhcp_static_mappings
List DHCP static mappings (IP reservations), optionally filtered by interface.
Each mapping carries `parent_id` (its DHCP server / interface) — pass that as
`interface` to delete_dhcp_static_mapping.
add_dhcp_static_mapping
Create a DHCP static mapping (IP reservation) for a MAC address.
Staged until apply_changes('dhcp') is called or apply=true is passed.
delete_dhcp_static_mapping
Delete a DHCP static mapping. Requires confirm=true.
`interface` is the mapping's DHCP server — the `parent_id` value returned by
list_dhcp_static_mappings; `mapping_id` is its `id` there. Staged until
apply_changes('dhcp') is called or apply=true is passed.
list_dns_host_overrides
List DNS Resolver host overrides (local DNS entries).
add_dns_host_override
Create a DNS host override entry in Unbound DNS Resolver.
Staged until apply_changes('dns') is called or apply=true is passed.
