Get the ARP table.
AI agents call get_arp_table to retrieve information from 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 queries and retrieves local network state information (ARP table) without side effects. It is a diagnostic read operation that does not modify data, execute commands, delete resources, or involve financial transactions. The low severity reflects that ARP table disclosure has limited direct blast radius—it reveals local network topology but does not enable direct system compromise or data destruction.
From the tool's definition Tool name 'get_arp_table' and description 'Get the ARP table' indicate a read-only operation that retrieves the Address Resolution Protocol table from the local system. No modification, execution, deletion, or financial operations are performed.
Attacks that exploit this kind of access
Get the ARP table. It is categorised as a Read tool in the Network MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Network MCP Server MCP server in PolicyLayer and add a rule for get_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 Network MCP Server. Nothing to install.
get_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_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_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_arp_table is provided by the Network MCP Server MCP server (labeveryday/network-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
