Query user delegation history.
AI agents call BinanceWalletQueryUserDelegationHistory 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 historical delegation data for a user on the BNB Chain ecosystem. It is a read-only operation that queries existing data without creating, modifying, deleting, or executing any state-changing operations. The low severity reflects that accessing historical delegation information poses minimal risk even if misused by an agent, as it does not move funds, execute code, or modify blockchain state.
From the tool's definition Tool name contains 'Query' and description states 'Query user delegation history' — indicates data retrieval with no modification or execution of transactions.

PolicyLayer is an MCP gateway — it sits between your AI agents and BNB Chain MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for BinanceWalletQueryUserDelegationHistory:
{
"version": "1",
"default": "deny",
"tools": {
"BinanceWalletQueryUserDelegationHistory": {}
}
}BinanceWalletQueryUserDelegationHistory is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
