AI agents call get_order to retrieve information from Paper 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 existing order information by identifier. It performs no modifications, deletions, executions, or financial transactions—merely querying and returning data about an order that already exists. The low severity reflects minimal blast radius: misuse would at worst expose order details the user already has access to, with no capability to alter state or commit financial actions.
From the tool's definition Tool name 'get_order' and description 'Get order details by ID' indicate a retrieval operation with no side effects. The description explicitly uses the verb 'Get', which is a read-only query action.
Documented attack patterns abuse exactly the kind of access get_order gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Paper MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_order:
{
"version": "1",
"default": "deny",
"tools": {
"get_order": {}
}
}get_order is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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