List firewall policies from the v2 API. These may include traffic rules with bandwidth limits. Raw response for discovery.
AI agents call unifi-firewall-policies to retrieve information from UniFi 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 firewall policy data without creating, modifying, or deleting policies. It is fundamentally a Read operation. Severity is medium (not low) because firewall policies are sensitive security configurations whose disclosure to an unauthorized AI agent could enable reconnaissance for network attacks, but the tool itself performs no network changes or enforcement actions.
From the tool's definition Tool explicitly 'List firewall policies' and returns 'Raw response for discovery' — retrieval without modification.
Attacks that exploit this kind of access
List firewall policies from the v2 API. These may include traffic rules with bandwidth limits. Raw response for discovery. It is categorised as a Read tool in the UniFi MCP Server MCP Server, which means it retrieves data without modifying state.
Register the UniFi MCP Server MCP server in PolicyLayer and add a rule for unifi-firewall-policies: 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 MCP Server. Nothing to install.
unifi-firewall-policies 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-firewall-policies 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-firewall-policies. 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-firewall-policies is provided by the UniFi MCP Server MCP server (philipvanlewis/unifi-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
