Retrieve a list of recent stock order history and their statuses
AI agents call stock_orders to retrieve information from Open Paper Trading MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only query of historical order data. It retrieves information about past transactions and their statuses without creating, modifying, deleting, or executing any trades. The action has no side effects on the trading account or market. While the server enables financial trading, this specific tool is limited to data retrieval, making it a Read category with low severity risk.
From the tool's definition Tool description explicitly states 'Retrieve a list of recent stock order history and their statuses' - a pure retrieval operation with no modification capability.
Documented attack patterns abuse exactly the kind of access stock_orders gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Open Paper Trading MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for stock_orders:
{
"version": "1",
"default": "deny",
"tools": {
"stock_orders": {}
}
}stock_orders is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Yes. Add a rate_limit block to the stock_orders 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 stock_orders. 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.
