THE RISK

Medium Risk

Why setBatchCollateralSwitch needs a policy

This tool modifies account collateral settings in batch, which is a reversible configuration change (coins can be re-enabled or re-disabled). However, changing collateral status has significant side effects: disabling collateral could trigger liquidation risk or restrict trading capabilities, and enabling collateral exposes assets as loan backing.

From the tool's definition The tool name 'setBatchCollateralSwitch' and description 'Batch enable or disable multiple coins as collateral' indicate it modifies collateral settings.

POLICY

How to control setBatchCollateralSwitch

PolicyLayer is an MCP gateway — it sits between your AI agents and Bybit MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for setBatchCollateralSwitch:

policy.json

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

setBatchCollateralSwitch 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.
