AI agents call get_positions to retrieve information from Moomoo Api without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool name 'get_positions' and its placement among read-only accessors (get_account_summary, get_assets, get_deals, get_historical_klines) indicates it queries current trading positions without modifying state. Even on a financial trading platform, retrieving position data is a Read operation.
From the tool's definition Tool name 'get_positions' with context from sibling tools (get_account_summary, get_assets, get_deals, get_historical_klines) indicates this retrieves trading position data.
Documented attack patterns abuse exactly the kind of access get_positions gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Moomoo Api, and nothing reaches the server without passing your rules. This is the rule we recommend for get_positions:
{
"version": "1",
"default": "deny",
"tools": {
"get_positions": {}
}
}get_positions is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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