Why BinanceFuturesChangeMarginType needs a policy

This tool modifies margin configuration for futures trading positions. While it doesn't directly move money, changing margin type (ISOLATED vs CROSSED) fundamentally affects risk exposure and liquidation behavior for active futures positions. It's an operational change to trading infrastructure rather than a direct financial transaction, placing it in Execute.

From the tool's definition Change margin type between ISOLATED and CROSSED for a USD-M Futures symbol

POLICY

How to control BinanceFuturesChangeMarginType

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 BinanceFuturesChangeMarginType:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "BinanceFuturesChangeMarginType": {
      "limits": [
        {
          "counter": "binancefutureschangemargintype_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

BinanceFuturesChangeMarginType 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.
