AI agents call get_orders to retrieve information from Fyers MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves past order information from the Fyers trading platform without modifying, executing, or affecting any financial transactions. It is purely informational, examining existing data rather than creating, modifying, or deleting records. The blast radius of misuse is minimal—an attacker could only view order history, not place trades or move funds.
From the tool's definition Tool name 'get_orders' and description 'Get order history' indicate a retrieval operation with no side effects. The verb 'Get' and context of querying historical data confirms this is a read-only action.
Documented attack patterns abuse exactly the kind of access get_orders gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Fyers MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_orders:
{
"version": "1",
"default": "deny",
"tools": {
"get_orders": {}
}
}get_orders is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get order history. It is categorised as a Read tool in the Fyers MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Fyers MCP Server MCP server in PolicyLayer and add a rule for get_orders: 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 Fyers MCP Server. Nothing to install.
get_orders 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_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 get_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.
get_orders is provided by the Fyers MCP Server MCP server (quantabox/fyers-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Fyers MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
