AI agents call scan_concepts_volume_anomaly 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.
This tool appears to scan and identify volume anomalies—a read-only query operation that retrieves analysis results without modifying data or triggering external actions.
From the tool's definition Tool name 'scan_concepts_volume_anomaly' suggests scanning/querying for anomalies in trading volume data across stock concepts.
Documented attack patterns abuse exactly the kind of access scan_concepts_volume_anomaly 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 scan_concepts_volume_anomaly:
{
"version": "1",
"default": "deny",
"tools": {
"scan_concepts_volume_anomaly": {}
}
}scan_concepts_volume_anomaly is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

scan_concepts_volume_anomaly. 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 scan_concepts_volume_anomaly: 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.
scan_concepts_volume_anomaly 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 scan_concepts_volume_anomaly 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 scan_concepts_volume_anomaly. 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.
scan_concepts_volume_anomaly 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.
