Get the order book depth for an options contract. Shows current bids and asks at various price levels.
AI agents call BinanceOptionsDepth 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.
The tool retrieves and displays order book information (bids/asks) for options contracts. This is a read-only data retrieval operation with no ability to modify state, execute transactions, or cause destructive actions. While the BNB Chain server can handle financial operations, this specific tool only queries market depth data without moving funds or creating obligations.
From the tool's definition Tool description states it "Get[s] the order book depth for an options contract. Shows current bids and asks at various price levels." This is a query operation retrieving market data with no side effects.
Documented attack patterns abuse exactly the kind of access BinanceOptionsDepth 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 BinanceOptionsDepth:
{
"version": "1",
"default": "deny",
"tools": {
"BinanceOptionsDepth": {}
}
}BinanceOptionsDepth is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the BNB Chain MCP server in PolicyLayer and add a rule for BinanceOptionsDepth: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches BNB Chain MCP. Nothing to install.
BinanceOptionsDepth is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the BinanceOptionsDepth 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 BinanceOptionsDepth. 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.
BinanceOptionsDepth 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.
