THE RISK

Why BinanceCheckDualInvestmentAccounts needs a policy

This tool retrieves account balance data without side effects. While it relates to a financial account, it performs only a read operation (balance lookup) rather than moving money, initiating trades, or modifying account state. The severity is low because unauthorized balance retrieval, while a privacy concern, does not directly result in asset loss or financial obligation.

From the tool's definition Tool name and description indicate retrieval of account balance information: 'Retrieve Dual Investment account balances'. No modification, deletion, or financial transaction occurs—only querying existing data.

POLICY

How to control BinanceCheckDualInvestmentAccounts

PolicyLayer is an MCP gateway — it sits between your AI agents and Sperax Ecosystem Crypto & DeFI MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for BinanceCheckDualInvestmentAccounts:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "BinanceCheckDualInvestmentAccounts": {}
  }
}

BinanceCheckDualInvestmentAccounts is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
