## Why pfsense_create_services_haproxy_frontend_acl is rated Medium

This tool creates new HAProxy frontend ACL entries, which are configuration objects that control traffic behavior and access policies. This is a Write operation (creates/modifies configuration reversibly). The severity is high because misconfigured ACLs on a pfSense firewall could disrupt network security policies, block legitimate traffic, or accidentally expose systems.

From the tool's own definition: "Tool name contains 'create' and operates on pfSense HAProxy frontend ACLs (access control lists) via REST API. The server description states it provides 'full control over pfSense firewalls' with tools covering 'firewall rules, NAT, VPN, services' and more."

## Use case

AI agents use pfsense_create_services_haproxy_frontend_acl to create or update resources in Pfsense, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Pfsense environment.
