WHAT IT DOES

What backup_config does on OPNsense MCP Server

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

RISK

Why backup_config is rated Medium

This tool creates/writes a backup file but does not destructively modify or delete existing data. While backups are generally defensive, the creation of a backup file in a firewall system could be misused to exfiltrate sensitive configuration data (passwords, VPN keys, firewall rules) if the backup is then retrieved.

From the tool's definition Tool name 'backup_config' and description 'Create a backup of the OPNsense configuration' indicate creation of a new backup artifact.

RECOMMENDED RULE

The rule that runs backup_config safely

PolicyLayer is an MCP gateway: it sits between your AI agents and OPNsense MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For backup_config, this is the rule to start with:

backup_config Rate-limited

backup_config stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect OPNsense MCP Server, apply this rule, and every backup_config call is checked against it from then on.
