AI agents call get_margins to retrieve information from Zerodha without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'get_' prefix strongly indicates a read-only operation that retrieves margin information from a Zerodha trading account. Margin queries have no side effects—they simply return account data. Confidence is slightly reduced due to empty description, but the naming pattern and server context (financial queries, not transactions) support Read classification.
From the tool's definition Tool name 'get_margins' indicates retrieval of margin information. No description provided, but naming convention and context (sibling tools include get_holdings, get_positions, get_order_history) suggest this queries account margin data without modification.
Documented attack patterns abuse exactly the kind of access get_margins gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Zerodha, and nothing reaches the server without passing your rules. This is the rule we recommend for get_margins:
{
"version": "1",
"default": "deny",
"tools": {
"get_margins": {}
}
}get_margins is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

get_margins. It is categorised as a Read tool in the Zerodha MCP Server, which means it retrieves data without modifying state.
Register the Zerodha MCP server in PolicyLayer and add a rule for get_margins: 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 Zerodha. Nothing to install.
get_margins 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_margins 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_margins. 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_margins is provided by the Zerodha MCP server (mtwn105/zerodha-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Zerodha, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
