List traffic matching lists at a site — named collections of ports or IPs reused in firewall/ACL rules. Returns: id, type (PORTS/IPV4_ADDRESSES/IPV6_ADDRESSES), name, items[]. Use for: finding the matching-list ID to reference from a firewall policy.
AI agents call unifi_list_traffic_matching_lists 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 performs a query operation to retrieve and display existing traffic matching lists from a UniFi site. It does not create, modify, delete, or execute any changes—it only reads and returns configuration data. The low severity reflects minimal blast radius: misuse retrieves network policy information but does not alter infrastructure or enable unauthorized access on its own.
From the tool's definition Tool description states 'List traffic matching lists' and 'Returns: id, type, name, items[]', with purpose to find IDs for reference. The verb 'list' and return-only operation indicate data retrieval with no side effects.

List traffic matching lists at a site — named collections of ports or IPs reused in firewall/ACL rules. Returns: id, type (PORTS/IPV4_ADDRESSES/IPV6_ADDRESSES), name, items[]. Use for: finding the matching-list ID to reference from a firewall policy. 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_list_traffic_matching_lists: 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_list_traffic_matching_lists 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_list_traffic_matching_lists 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_list_traffic_matching_lists. 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_list_traffic_matching_lists 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.
