WHAT IT DOES

What add_acl_rule does on Ikuai

AI agents use add_acl_rule 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_acl_rule is rated Medium

This tool creates new access control list (ACL) rules on the router, which is a reversible Write operation that modifies network policies. While it could potentially impact network security and operations significantly (justifying 'high' severity), it does not execute arbitrary code (Execute), delete data (Destructive), or move money (Financial).

From the tool's definition Tool name 'add_acl_rule' with description '添加 ACL 规则' (Add ACL rule). ACL rules control network access control, including port, protocol, and traffic filtering policies. This creates new security policy rules that modify router behavior.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs add_acl_rule 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_acl_rule, this is the rule to start with:

add_acl_rule Rate-limited

add_acl_rule 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_acl_rule call is checked against it from then on.
