Get the evaluation order of user-defined firewall policies for a specific (source zone, destination zone) pair. Returns: beforeSystemDefined[] and afterSystemDefined[] arrays of policy IDs. System-defined rules sit between these two arrays.
AI agents call unifi_get_firewall_policy_ordering to retrieve information from UniFi Network MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries the ordering/configuration of existing firewall policies. It returns data about policy evaluation order but does not create, modify, delete, or execute any policies. It is a pure read operation with no blast radius if misused by an AI agent, as it only exposes existing configuration information.
From the tool's definition Tool name includes 'get' and description states 'Get the evaluation order...Returns: beforeSystemDefined[] and afterSystemDefined[] arrays' - explicitly a retrieval operation with no modifications or side effects.

Get the evaluation order of user-defined firewall policies for a specific (source zone, destination zone) pair. Returns: beforeSystemDefined[] and afterSystemDefined[] arrays of policy IDs. System-defined rules sit between these two arrays. It is categorised as a Read tool in the UniFi Network MCP Server MCP Server, which means it retrieves data without modifying state.
Register the UniFi Network MCP Server MCP server in PolicyLayer and add a rule for unifi_get_firewall_policy_ordering: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches UniFi Network MCP Server. Nothing to install.
unifi_get_firewall_policy_ordering is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the unifi_get_firewall_policy_ordering rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for unifi_get_firewall_policy_ordering. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
unifi_get_firewall_policy_ordering is provided by the UniFi Network MCP Server MCP server (owine/unifi-network-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
