Test connectivity to Binance API. Returns empty object if successful. Use to verify API is reachable.
AI agents call bn_ping to retrieve information from Node2flow/binance without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a health-check or diagnostic tool that performs a GET request to test connectivity. It retrieves no sensitive data, makes no state changes, executes no trades, and has no side effects. The worst-case misuse is a minor resource waste or denial-of-service attempt against Binance's infrastructure, not a direct security impact to the user's account or funds.
From the tool's definition Tool name 'bn_ping' and description 'Test connectivity to Binance API. Returns empty object if successful.' indicates a read-only diagnostic operation that queries API status without modifying or executing any trading logic.
Attacks that exploit this kind of access
Test connectivity to Binance API. Returns empty object if successful. Use to verify API is reachable. It is categorised as a Read tool in the Node2flow/binance MCP Server, which means it retrieves data without modifying state.
Register the Node2flow/binance MCP server in PolicyLayer and add a rule for bn_ping: 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 Node2flow/binance. Nothing to install.
bn_ping 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 bn_ping 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 bn_ping. 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.
bn_ping is provided by the Node2flow/binance MCP server (node2flow-th/binance-mcp-community). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
