Find interfaces by their current status
AI agents call find_interfaces_by_status to retrieve information from pfSense Enhanced 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 information about firewall interfaces and their operational status. It performs a read-only query with no side effects—it does not create, modify, delete, or execute operations. The blast radius is minimal; misuse would at worst reveal network interface configuration details, which is informational rather than actionable harm.
From the tool's definition Tool name 'find_interfaces_by_status' and description 'Find interfaces by their current status' indicate a query/retrieval operation.

Register the pfSense Enhanced MCP Server MCP server in PolicyLayer and add a rule for find_interfaces_by_status: 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 pfSense Enhanced MCP Server. Nothing to install.
find_interfaces_by_status 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 find_interfaces_by_status 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 find_interfaces_by_status. 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.
find_interfaces_by_status is provided by the pfSense Enhanced MCP Server MCP server (mmaxwellcb/pfsesen_mcp_2). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
