Create a new user data stream to receive account updates via WebSocket.
AI agents invoke BinanceNewUserDataStream to trigger actions in Binance MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
BinanceNewUserDataStream triggers real processes with real consequences. An agent gone sideways doesn't fire it once — it starts dozens of builds, sends mass notifications, or burns through compute before anyone looks up.
Documented attack patterns abuse exactly the kind of access BinanceNewUserDataStream gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Binance MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for BinanceNewUserDataStream:
{
"version": "1",
"default": "deny",
"tools": {
"BinanceNewUserDataStream": {
"limits": [
{
"counter": "binancenewuserdatastream_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}BinanceNewUserDataStream stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Create a new user data stream to receive account updates via WebSocket. It is categorised as a Execute tool in the Binance MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Binance MCP Server MCP server in PolicyLayer and add a rule for BinanceNewUserDataStream: 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 Binance MCP Server. Nothing to install.
BinanceNewUserDataStream is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the BinanceNewUserDataStream 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 BinanceNewUserDataStream. 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.
BinanceNewUserDataStream is provided by the Binance MCP Server MCP server (nirholas/binance-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
