List all port forwarding rules configured on the UniFi gateway.
AI agents call list_port_forwards 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 queries and returns existing port forwarding configuration data without creating, modifying, deleting, or executing any operations. It is a read-only informational action. Severity is low because port forwarding rules are configuration metadata; exposure of this information has limited direct impact compared to tools that can modify network settings or trigger actions.
From the tool's definition Tool name 'list_port_forwards' and description 'List all port forwarding rules' indicate a retrieval operation with no modification or execution.

List all port forwarding rules configured on the UniFi gateway. 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 list_port_forwards: 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.
list_port_forwards 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 list_port_forwards 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 list_port_forwards. 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.
list_port_forwards is provided by the UniFi MCP Server MCP server (nathan-bw/unifi-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
