What find_mac_on_switch does on Hpe Networking
AI agents call find_mac_on_switch to retrieve information from Hpe Networking without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why find_mac_on_switch is rated Low
This tool performs a read-only lookup of MAC address port associations on a switch. It queries existing data (which switch port has learned a given MAC address) with no side effects, no data modification, and no resource depletion. The only concern is information disclosure about network topology, which is low severity since network administrators typically have legitimate access to such diagnostics.
From the tool's definition Tool description states 'Find which port a MAC address is learned on' — a query operation that retrieves information about network topology without modifying any state.
Attacks that exploit this kind of access
The rule that runs find_mac_on_switch safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Hpe Networking, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For find_mac_on_switch, this is the rule to start with:
find_mac_on_switch is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Hpe Networking, apply this rule, and every find_mac_on_switch call is checked against it from then on.
Questions about find_mac_on_switch
Find which port a MAC address is learned on for a CX switch. It is categorised as a Read tool in the Hpe Networking MCP Server, which means it retrieves data without modifying state.
Register the Hpe Networking MCP server in PolicyLayer and add a rule for find_mac_on_switch: 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 Hpe Networking. Nothing to install.
find_mac_on_switch 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_mac_on_switch 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_mac_on_switch. 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_mac_on_switch is provided by the Hpe Networking MCP server (secure-ssid/hpe-networking-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
