What DescribeDataLibrary does on Ioacloud
AI agents call DescribeDataLibrary 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 |
|---|---|---|---|
OsType | number | — | 系统类型（0: win，1：linux，2: mac，3: win_srv，4：android，5：ios 默认值0）(只支持32位) |

Parameters from the server's own tool schema.
Why DescribeDataLibrary is rated Low
Even though DescribeDataLibrary 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 DescribeDataLibrary 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 DescribeDataLibrary, this is the rule to start with:
DescribeDataLibrary 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 DescribeDataLibrary call is checked against it from then on.

DescribeDataLibrary accepts 3 parameters: OsType, Condition, DomainInstanceId. 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 DescribeDataLibrary: 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.
DescribeDataLibrary 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 DescribeDataLibrary 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 DescribeDataLibrary. 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.
DescribeDataLibrary 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.
