Get information about available WebSocket streams on Binance.US. Returns details about: - Market data streams (public) - User data streams (requires listen key) - Connection URLs and limits
AI agents call binance_us_websocket_info 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 retrieves metadata about WebSocket stream availability and configuration without executing trades, modifying data, or triggering external operations. Even though it mentions 'user data streams', it only exposes information about what streams exist and their connection details, not user data itself. This is a straightforward Read operation with minimal security risk.
From the tool's definition Tool provides information about 'available WebSocket streams' and 'details about market data streams (public)' and 'connection URLs and limits'. No modification, deletion, or execution of operations occurs; purely informational retrieval.
Documented attack patterns abuse exactly the kind of access binance_us_websocket_info 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 binance_us_websocket_info:
{
"version": "1",
"default": "deny",
"tools": {
"binance_us_websocket_info": {}
}
}binance_us_websocket_info is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get information about available WebSocket streams on Binance.US. Returns details about: - Market data streams (public) - User data streams (requires listen key) - Connection URLs and limits. It is categorised as a Read tool in the BNB Chain MCP MCP Server, which means it retrieves data without modifying state.
Register the BNB Chain MCP server in PolicyLayer and add a rule for binance_us_websocket_info: 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.
binance_us_websocket_info 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 binance_us_websocket_info 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 binance_us_websocket_info. 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.
binance_us_websocket_info 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.
