获取任务列表
AI agents call ListTasks 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 |
|---|---|---|---|
Ids | array | — | 任务的ID列表，可根据任务Id批量查询任务 |
Name | string | — | 名称，支持模糊查询 |
Owner | string | — | 任务的责任人的账号ID |
SortBy | string | — | 排序字段。支持修改时间、创建时间等字段，格式为"排序字段+排序方式(Desc/Asc)"（Asc可以缺省）。排序字段的枚举值如下：- `ModifyTime (Desc/Asc)`- `CreateTime (Desc/Asc)`- `Id (Desc/Asc)` 默认值：`Id Desc` |
PageSize | number | — | 每页的条目数，默认为10 |
TaskType | string | — | 任务类型。例如：- ODPS_SQL- SPARK- PY_ODPS- PY_ODPS3- ODPS_SCRIPT- ODPS_MR- COMPONENT_SQL- EMR_HIVE- EMR_MR- EMR_SPARK_SQL- EMR_SPARK- EMR_SHELL- EMR_PRESTO- EMR_IMPALA |
ProjectId | number | Yes | 项目ID |
PageNumber | number | — | 页码，从1开始，默认为1 |
ProjectEnv | string | — | 项目环境 |
WorkflowId | number | — | 所属工作流的ID |
TriggerType | string | — | 触发方式类型 |
RuntimeResource | string | — | 资源组信息，这里请填入调度资源组标识符 |
Parameters from the server's own tool schema.
Even though ListTasks 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
获取任务列表. It is categorised as a Read tool in the Alibabacloud Dataworks MCP Server, which means it retrieves data without modifying state.
ListTasks accepts 12 parameters: Ids, Name, Owner, SortBy, PageSize, TaskType, ProjectId, PageNumber, ProjectEnv, WorkflowId, TriggerType, RuntimeResource. Required: 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 ListTasks: 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.
ListTasks 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 ListTasks 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 ListTasks. 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.
ListTasks 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.
