AI agents call get_fee_info to retrieve information from Binance MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'get_' prefix and naming convention strongly suggest this retrieves fee structure data (trading fees, withdrawal fees, etc.) without modifying state. Although the description is absent, the tool's position among other non-destructive getters (balance queries, order book reads) and the nature of fee data (informational, read-only) place it in the Read category with low severity.
From the tool's definition Tool name 'get_fee_info' with 'get_' prefix indicates data retrieval. Description is empty, but context shows this server handles fee-related queries alongside read operations like 'get_account_snapshot', 'get_balance', 'get_order_book'.
Documented attack patterns abuse exactly the kind of access get_fee_info gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Binance MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_fee_info:
{
"version": "1",
"default": "deny",
"tools": {
"get_fee_info": {}
}
}get_fee_info is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
