AI agents call rebalancing_history 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 queries and returns historical trading records for a portfolio. It performs a read-only operation that retrieves past transaction data without any side effects, modifications, or ability to execute trades. The minimal blast radius of misuse is limited to exposure of historical transaction information, which is why severity is low.
From the tool's definition The tool description is '获取组合历史交易信息' (retrieve portfolio historical transaction information). The function retrieves historical data with a single read-only parameter (cube_symbol: portfolio code).

{
"version": "1",
"default": "deny",
"tools": {
"rebalancing_history": {}
}
} rebalancing_history is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
