AI agents call quote_detail 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 stock market quotation details from the Xueqiu API. It queries and returns financial data without modifying, executing commands, or performing any irreversible actions. The low severity reflects minimal risk even if misused—an AI agent can only read market data, not execute trades, move funds, or alter data.

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