获取数据开发节点的依赖节点
AI agents call ListNodeDependencies to retrieve information from Alibabacloud Dataworks without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
Id | string | number | Yes | 数据开发节点的唯一标识符 |
PageSize | number | — | 每页显示的条数，默认为10条，最大100条 |
ProjectId | number | Yes | DataWorks工作空间的ID |
PageNumber | number | — | 页码，从1开始。默认值为1 |
Parameters from the server's own tool schema.
Even though ListNodeDependencies 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
获取数据开发节点的依赖节点. It is categorised as a Read tool in the Alibabacloud Dataworks MCP Server, which means it retrieves data without modifying state.
ListNodeDependencies accepts 4 parameters: Id, PageSize, ProjectId, PageNumber. Required: Id, ProjectId. The full parameter table on this page comes from the server's own tool schema.
Register the Alibabacloud Dataworks MCP server in PolicyLayer and add a rule for ListNodeDependencies: 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 Alibabacloud Dataworks. Nothing to install.
ListNodeDependencies 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 ListNodeDependencies 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 ListNodeDependencies. 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.
ListNodeDependencies is provided by the Alibabacloud Dataworks MCP server (alibabacloud-dataworks-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
