Why BinancePutUserDataStream needs a policy

This tool updates/modifies an existing resource (a user data stream listen key's validity period) rather than reading, executing code, deleting, or moving funds. However, confidence is moderate because the description is terse and doesn't explicitly confirm the nature of the modification.

From the tool's definition Tool name 'BinancePutUserDataStream' with description 'Extend the validity of a user data stream listen key' indicates a PUT operation that modifies stream configuration state on Binance.

POLICY

How to control BinancePutUserDataStream

PolicyLayer is an MCP gateway — it sits between your AI agents and Sperax Ecosystem Crypto & DeFI MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for BinancePutUserDataStream:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "BinancePutUserDataStream": {
      "limits": [
        {
          "counter": "binanceputuserdatastream_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

BinancePutUserDataStream 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.
