Get the ARP table from a CX switch.
AI agents call get_cx_arp_table to retrieve information from API-Central without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves network state information (ARP table entries) from a switch without creating, modifying, deleting, or executing any operations. ARP table queries are informational and pose minimal risk even if misused by an agent, as they cannot alter network configuration or state.
From the tool's definition Tool name 'get_cx_arp_table' and description 'Get the ARP table from a CX switch' indicate data retrieval with no modification or side effects. The verb 'get' and the read-only nature of querying ARP tables confirm this is a retrieval operation.
Attacks that exploit this kind of access
Get the ARP table from a CX switch. It is categorised as a Read tool in the API-Central MCP Server, which means it retrieves data without modifying state.
Register the API-Central MCP server in PolicyLayer and add a rule for get_cx_arp_table: 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 API-Central. Nothing to install.
get_cx_arp_table 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 get_cx_arp_table 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 get_cx_arp_table. 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.
get_cx_arp_table is provided by the API-Central MCP server (secure-ssid/centralmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
