WHAT IT DOES

What add_arp_binding does on Ikuai

AI agents use add_arp_binding to create or update resources in Ikuai, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Ikuai environment.

RISK

Why add_arp_binding is rated Medium

This tool creates or modifies ARP bindings, which are network layer mappings. While reversible (can be removed or updated), unauthorized ARP binding modifications can enable ARP spoofing, network hijacking, or denial-of-service attacks. The impact depends on what bindings are created, making it a Write-category risk rather than Execute.

From the tool's definition Tool name 'add_arp_binding' and description '添加 ARP 绑定' (Add ARP binding) indicate creation/modification of ARP table entries. ARP bindings map IP addresses to MAC addresses on a network.

RECOMMENDED RULE

The rule that runs add_arp_binding safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Ikuai, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For add_arp_binding, this is the rule to start with:

add_arp_binding Rate-limited

add_arp_binding stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

The button opens the PolicyLayer dashboard: create your workspace, connect Ikuai, apply this rule, and every add_arp_binding call is checked against it from then on.
