AI agents call index_perf_7 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 performance metrics for a financial index—a read-only query operation. It has no capability to modify, execute code, delete data, or move money. The blast radius of misuse is minimal; an agent could only retrieve public market data.
From the tool's definition Tool name 'index_perf_7' and description '获取指数最近7天收益数据' (fetch index performance data for the last 7 days) indicate data retrieval. The argument 'index_code' is a query parameter, not a destructive or executable operation.
Documented attack patterns abuse exactly the kind of access index_perf_7 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 index_perf_7:
{
"version": "1",
"default": "deny",
"tools": {
"index_perf_7": {}
}
}index_perf_7 is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

获取指数最近7天收益数据 Args: index_code: 指数代码. 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 index_perf_7: 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.
index_perf_7 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 index_perf_7 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 index_perf_7. 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.
index_perf_7 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.
