AI agents call index_basic_info 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 or queries data about financial indices without creating, modifying, deleting, or executing any operations. It is a read-only data retrieval operation with minimal security risk even if misused by an agent, as it only returns publicly available market reference information.
From the tool's definition Tool name 'index_basic_info' and description '获取指数基本信息' (get index basic information) indicate a query operation that retrieves static metadata about stock indices. The single argument 'index_code' is a lookup parameter with no side effects.
Documented attack patterns abuse exactly the kind of access index_basic_info 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_basic_info:
{
"version": "1",
"default": "deny",
"tools": {
"index_basic_info": {}
}
}index_basic_info 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.
获取指数基本信息 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_basic_info: 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_basic_info 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_basic_info 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_basic_info. 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_basic_info 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.
