AI agents call nav_daily 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 or current net asset value (NAV) data for a portfolio identified by its symbol. It performs a read-only query against financial data without creating, modifying, executing, or deleting anything. The low severity reflects that misuse would only expose financial information, not cause transactions or data loss.
From the tool's definition Tool name 'nav_daily' and description '获取组合净值数据' (get portfolio net asset value data) indicate a data retrieval operation.
Documented attack patterns abuse exactly the kind of access nav_daily gives an agent:
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 nav_daily:
{
"version": "1",
"default": "deny",
"tools": {
"nav_daily": {}
}
}nav_daily is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
获取组合净值数据 Args: cube_symbol: 组合代码. It is categorised as a Read tool in the Xueqiu MCP MCP Server, which means it retrieves data without modifying state.
Register the Xueqiu MCP server in PolicyLayer and add a rule for nav_daily: 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 Xueqiu MCP. Nothing to install.
nav_daily 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 nav_daily 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 nav_daily. 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.
nav_daily is provided by the Xueqiu MCP server (liqiongyu/xueqiu_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Xueqiu MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
