AI agents call BinanceDeliveryBalance to retrieve information from BNB Chain MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves account balance data (a read operation) with no side effects, modifications, or triggering of external actions. While it accesses financial account information, it does not move money, commit financial obligations, or perform financial transactions—it merely queries existing data.

{
"version": "1",
"default": "deny",
"tools": {
"BinanceDeliveryBalance": {}
}
}BinanceDeliveryBalance is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
