AI agents call list_datasets to retrieve information from Xmo Data without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a query/retrieval operation that lists existing datasets and returns metadata. It has no capability to modify, delete, execute, or commit financial actions. The read-only nature and informational output clearly places it in the Read category with low severity since listing datasets poses minimal security risk when an AI agent invokes it.
From the tool's definition Tool name 'list_datasets' combined with description indicating it 'lists all datasets created by user' and 'returns basic information including ID, name and time range' - purely retrieves data with no modifications or side effects.
Attacks that exploit this kind of access
列出用户创建的所有数据集。返回数据集的基本信息，包括ID、名称和时间范围。. It is categorised as a Read tool in the Xmo Data MCP Server, which means it retrieves data without modifying state.
Register the Xmo Data MCP server in PolicyLayer and add a rule for list_datasets: 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 Xmo Data. Nothing to install.
list_datasets 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 list_datasets 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 list_datasets. 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.
list_datasets is provided by the Xmo Data MCP server (xmo-data-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
list_datasets is one line of Xmo Data's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
