AI agents call blocktrans to retrieve information from Xueqiu MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves historical block transaction data from the Xueqiu stock market API. It performs a query operation with no side effects, no data modification, and no execution of arbitrary code. The blast radius of misuse is minimal—an AI could retrieve unnecessary stock data but cannot manipulate markets, delete information, or execute commands. Classified as Read with low severity.
From the tool's definition Tool name 'blocktrans' and description '获取大宗交易数据' (retrieve block/large transaction data) indicate data retrieval without modification. The verb '获取' (get/fetch) is a read operation.

PolicyLayer is an MCP gateway — it sits between your AI agents and Xueqiu MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for blocktrans:
{
"version": "1",
"default": "deny",
"tools": {
"blocktrans": {}
}
}blocktrans is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
