AI agents call calculate_order_margin to retrieve information from Turtlestack Lite without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool calculates/estimates the margin required for an order. It performs a computation and returns information without placing any order, moving funds, or modifying state. Similar to the sibling tools 'calculate_kite_order_margins' and 'calculate_kite_order_charges', this is a read/query operation that retrieves margin requirements.
From the tool's definition Calculate order margin for Groww orders
Documented attack patterns abuse exactly the kind of access calculate_order_margin gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Turtlestack Lite, and nothing reaches the server without passing your rules. This is the rule we recommend for calculate_order_margin:
{
"version": "1",
"default": "deny",
"tools": {
"calculate_order_margin": {}
}
}calculate_order_margin 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.
Calculate order margin for Groww orders. It is categorised as a Read tool in the Turtlestack Lite MCP Server, which means it retrieves data without modifying state.
Register the Turtlestack Lite MCP server in PolicyLayer and add a rule for calculate_order_margin: 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 Turtlestack Lite. Nothing to install.
calculate_order_margin 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 calculate_order_margin 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 calculate_order_margin. 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.
calculate_order_margin is provided by the Turtlestack Lite MCP server (turtlehq-tech/turtlestack-lite). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Turtlestack Lite, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
