POLICY

How to control BinancePortfolioMarginCmChangeLeverage

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 BinancePortfolioMarginCmChangeLeverage:

policy.json

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

BinancePortfolioMarginCmChangeLeverage 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.
