Get Kline/candlestick data for a trading pair. Returns OHLCV data.
AI agents call binance_us_klines 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 only queries and retrieves historical market data. It has no side effects—it does not execute trades, transfer funds, modify data, or trigger external operations.

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