AI agents call fund_growth 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 growth metrics for a mutual fund identified by its code. It is a read-only query operation with no side effects, consistent with the Read category. Severity is low because misuse would only expose financial market data already available through public sources, posing no destructive or operational risk.
From the tool's definition Tool name 'fund_growth' and description '获取基金增长数据' (get fund growth data) indicates data retrieval. The single argument 'fund_code' is a query parameter. No modification, deletion, or execution of external operations occurs.
Documented attack patterns abuse exactly the kind of access fund_growth 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 fund_growth:
{
"version": "1",
"default": "deny",
"tools": {
"fund_growth": {}
}
}fund_growth is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

获取基金增长数据 Args: fund_code: 基金代码. 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 fund_growth: 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.
fund_growth 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 fund_growth 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 fund_growth. 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.
fund_growth 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.
Free to start. No card required.
