What list_acl_rules does on Ikuai
AI agents call list_acl_rules to retrieve information from Ikuai without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why list_acl_rules is rated Low
This tool queries and retrieves ACL (access control list) rules from the router, which is a read-only operation with no side effects. However, severity is elevated to medium because ACL rules are security-critical configuration that could reveal network access policies and security posture to an AI agent, potentially enabling informed attacks or policy circumvention strategies.
From the tool's definition Tool name 'list_acl_rules' and description '列出 ACL 访问控制规则' (list ACL access control rules) indicate retrieval of existing access control configuration without modification.
Attacks that exploit this kind of access
The rule that runs list_acl_rules 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 list_acl_rules, this is the rule to start with:
list_acl_rules 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 Ikuai, apply this rule, and every list_acl_rules call is checked against it from then on.

Register the Ikuai MCP server in PolicyLayer and add a rule for list_acl_rules: 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 Ikuai. Nothing to install.
list_acl_rules 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 list_acl_rules 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.
