WHAT IT DOES

What BinanceNewUserDataStream does on Binance MCP Server

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.

RISK

Why BinanceNewUserDataStream is rated High

While the tool itself reads data (account updates), it executes an operation that initiates and maintains an external service connection (WebSocket stream). This goes beyond passive Read (which would be getting historical data or snapshots). The tool triggers an active, stateful operation on Binance's servers.

From the tool's definition Tool creates a new user data stream, which initiates a WebSocket connection to receive account updates. This is an active operation that establishes a persistent connection to Binance's infrastructure with side effects beyond simple data retrieval.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs BinanceNewUserDataStream safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Binance MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For BinanceNewUserDataStream, this is the rule to start with:

BinanceNewUserDataStream Rate-limited

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.

        }
      ]
    }
  }
}

RATE-LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Binance MCP Server, apply this rule, and every BinanceNewUserDataStream call is checked against it from then on.
