AI agents call macro_scan to retrieve information from Tushare MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Based on the Tushare MCP Server's purpose and sibling tools, 'macro_scan' most likely retrieves macroeconomic or market scan data without modifying state. The absence of destructive keywords (delete, drop) and financial transaction language (pay, transfer) supports Read classification. However, confidence is reduced to 0.7 due to the empty tool description providing no direct evidence.
From the tool's definition Tool name 'macro_scan' and server context (Tushare financial data API) suggest querying macroeconomic or market data.
Documented attack patterns abuse exactly the kind of access macro_scan gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Tushare MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for macro_scan:
{
"version": "1",
"default": "deny",
"tools": {
"macro_scan": {}
}
}macro_scan is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

macro_scan. It is categorised as a Read tool in the Tushare MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Tushare MCP Server MCP server in PolicyLayer and add a rule for macro_scan: 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 Tushare MCP Server. Nothing to install.
macro_scan 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 macro_scan 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 macro_scan. 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.
macro_scan is provided by the Tushare MCP Server MCP server (zhewenzhang/tushare_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
