Quarterly operation capability data.
AI agents call get_operation_data to retrieve information from A Share without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves historical quarterly operational metrics for A-shares (Chinese stocks). The API pattern matches standard financial data read operations—no modification, deletion, code execution, or financial transactions. The worst-case misuse is information disclosure of public financial statements, which has low real-world impact. Classified as Read with low severity.
From the tool's definition Tool name 'get_operation_data' and description 'Quarterly operation capability data' indicate data retrieval only. No write, execute, or destructive operations are mentioned.
Documented attack patterns abuse exactly the kind of access get_operation_data gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and A Share, and nothing reaches the server without passing your rules. This is the rule we recommend for get_operation_data:
{
"version": "1",
"default": "deny",
"tools": {
"get_operation_data": {}
}
}get_operation_data is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Quarterly operation capability data. It is categorised as a Read tool in the A Share MCP Server, which means it retrieves data without modifying state.
Register the A Share MCP server in PolicyLayer and add a rule for get_operation_data: 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 A Share. Nothing to install.
get_operation_data 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 get_operation_data 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 get_operation_data. 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.
get_operation_data is provided by the A Share MCP server (shouldnotappearcalm/a-share-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from A Share, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
