How to control binance_us_cust_transfer_history ↓

AI agents call binance_us_cust_transfer_history 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.

Low Risk

This tool only retrieves historical transfer records and does not initiate, modify, or delete any transfers. It is a read-only query of past transaction data. Severity is low as it only exposes transfer history, though it does require a custodial API key indicating sensitive access.

  "default": "deny",
  "tools": {
    "binance_us_cust_transfer_history": {}
