AI agents call main_indicator 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 financial indicator data from the Xueqiu stock market API. It performs a read-only query operation with no side effects, no code execution, no data modification, and no financial transactions. The blast radius of misuse is minimal—an AI agent could retrieve unnecessary data or perform redundant queries, but cannot cause harm to data integrity, execute operations, or incur financial obligations.
From the tool's definition Tool name 'main_indicator' and description '获取F10主要指标数据' (Get F10 main indicator data) indicate data retrieval.
Documented attack patterns abuse exactly the kind of access main_indicator 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 main_indicator:
{
"version": "1",
"default": "deny",
"tools": {
"main_indicator": {}
}
}main_indicator is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

获取F10主要指标数据. 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 main_indicator: 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.
main_indicator 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 main_indicator 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 main_indicator. 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.
main_indicator 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.
