What DescribeDeviceList does on Ioacloud
AI agents call DescribeDeviceList 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.

Why DescribeDeviceList is rated Low
Even though DescribeDeviceList 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
The rule that runs DescribeDeviceList 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 DescribeDeviceList, this is the rule to start with:
DescribeDeviceList 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 Ioacloud, apply this rule, and every DescribeDeviceList call is checked against it from then on.
Questions about DescribeDeviceList
[device] 查询满足条件的终端数据详情，私有化调用path为：/capi/Assets/Device/DescribeDeviceList 前置：DescribeRootGroupId 或 DescribeDeviceChildGroups 拿 GroupId (GroupId 与 OsType 必须匹配)。. It is categorised as a Read tool in the Ioacloud MCP Server, which means it retrieves data without modifying state.
DescribeDeviceList accepts 12 parameters: Sort, OsType, Status, Filters, GroupId, PageNum, GroupIds, NewScope, PageSize, Condition, DeviceIds, LoginType. The full parameter table on this page comes from the server's own tool schema.
Register the Ioacloud MCP server in PolicyLayer and add a rule for DescribeDeviceList: 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 Ioacloud. Nothing to install.
DescribeDeviceList 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 DescribeDeviceList 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 DescribeDeviceList. 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.
DescribeDeviceList is provided by the Ioacloud MCP server (@ioacloud/ioacloud-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
