WHAT IT DOES

What DescribeNGNPolicyList does on Ioacloud

AI agents call DescribeNGNPolicyList to retrieve information from Ioacloud without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Parameter	Type	Required	Description
`UserId`	number	—	用户Id,与组Id二选一填写,且必须填写一个
`GroupId`	number	—	组Id,与用户Id二选一填写,且必须填写一个

Parameters from the server's own tool schema.

RISK

Why DescribeNGNPolicyList is rated Low

Even though DescribeNGNPolicyList only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs DescribeNGNPolicyList safely

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

DescribeNGNPolicyList Allowed

DescribeNGNPolicyList is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "DescribeNGNPolicyList": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

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