POLICY

How to control BinanceSubAccountMarginSummary

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 BinanceSubAccountMarginSummary:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "BinanceSubAccountMarginSummary": {}
  }
}

BinanceSubAccountMarginSummary is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
