Get kline/candlestick data for an options contract. Returns OHLCV data for technical analysis.
AI agents call BinanceOptionsKlines 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 performs a read-only query operation to fetch historical price data. It has no side effects, cannot modify data, execute transactions, or trigger financial operations. The blast radius of misuse is minimal—an agent could only retrieve existing market data, not cause financial loss or irreversible changes.
From the tool's definition Tool retrieves historical candlestick (OHLCV) data for options contracts for 'technical analysis' purposes. No modification, deletion, or execution of trades/operations is performed—purely data retrieval.
Documented attack patterns abuse exactly the kind of access BinanceOptionsKlines gives an agent:
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 BinanceOptionsKlines:
{
"version": "1",
"default": "deny",
"tools": {
"BinanceOptionsKlines": {}
}
}BinanceOptionsKlines is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
