Cancels a previously placed limit order using the orderId and returns the cancellation status along with the orderId.
AI agents use BinanceConvertCancelLimitOrder to create or update resources in BNB Chain MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your BNB Chain MCP environment.
While this tool modifies financial orders, it is classified as Write rather than Financial because the act of cancellation is reversible (the user can place a new order) and does not constitute a direct movement of funds. However, severity is high because cancelling limit orders has significant financial consequences for trading strategies and account state.
From the tool's definition Tool explicitly cancels a previously placed limit order, which is a financial transaction modification. The description states it 'Cancels a previously placed limit order using the orderId and returns the cancellation status.' This is a reversible…
Documented attack patterns abuse exactly the kind of access BinanceConvertCancelLimitOrder 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 BinanceConvertCancelLimitOrder:
{
"version": "1",
"default": "deny",
"tools": {
"BinanceConvertCancelLimitOrder": {
"limits": [
{
"counter": "binanceconvertcancellimitorder_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}BinanceConvertCancelLimitOrder stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Cancels a previously placed limit order using the orderId and returns the cancellation status along with the orderId. It is categorised as a Write tool in the BNB Chain MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the BNB Chain MCP server in PolicyLayer and add a rule for BinanceConvertCancelLimitOrder: 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.
BinanceConvertCancelLimitOrder is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the BinanceConvertCancelLimitOrder 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 BinanceConvertCancelLimitOrder. 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.
BinanceConvertCancelLimitOrder 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.
