获取数据的大概情况，例如表头信息、表头对应的字段类型、数据条数等
AI agents call data_overview to retrieve information from Xtai Mcp Data Analysis without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs data introspection—querying headers, data types, and row counts. These are passive retrieval operations that do not modify, execute code on external systems, delete, or cause financial effects. It fits squarely within the Read category with low severity risk.
From the tool's definition Tool retrieves metadata about data structure: '获取数据的大概情况，例如表头信息、表头对应的字段类型、数据条数等' (get data overview, such as header information, field types corresponding to headers, row counts). These are read-only inspection operations with no modifications or side effects.
Attacks that exploit this kind of access
获取数据的大概情况，例如表头信息、表头对应的字段类型、数据条数等. It is categorised as a Read tool in the Xtai Mcp Data Analysis MCP Server, which means it retrieves data without modifying state.
Register the Xtai Mcp Data Analysis MCP server in PolicyLayer and add a rule for data_overview: 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 Xtai Mcp Data Analysis. Nothing to install.
data_overview 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 data_overview 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 data_overview. 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.
data_overview is provided by the Xtai Mcp Data Analysis MCP server (vaesonshu/xtai-mcp-data-analysis). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
