Get candlestick data (klines) for a specific trading pair and interval.
AI agents call BinanceKlines 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 queries historical price/market data from Binance. It has no capability to execute trades, modify wallets, access private keys, or perform any irreversible action. The blast radius of misuse is minimal—an AI agent with access could only retrieve publicly available market data, which poses negligible security risk.
From the tool's definition Tool retrieves candlestick data (klines) for trading pairs without modifying any state. The verb 'Get' and the function of fetching historical market data indicates a read-only operation with no side effects.
Documented attack patterns abuse exactly the kind of access BinanceKlines 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 BinanceKlines:
{
"version": "1",
"default": "deny",
"tools": {
"BinanceKlines": {}
}
}BinanceKlines is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Yes. Add a rate_limit block to the BinanceKlines rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for BinanceKlines. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
BinanceKlines is provided by the BNB Chain MCP server (nirholas/bnbchain-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
