Why accountRepay needs a policy

Repaying liabilities on a trading account directly moves cryptocurrency assets to settle financial obligations, making this a Financial category action. Misuse could result in unintended fund movements or premature repayment of loans, hence high severity.

From the tool's definition 'Manually repay the liabilities of Unified account' — repaying liabilities commits a financial obligation by moving funds to settle debt on the exchange.

POLICY

How to control accountRepay

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 accountRepay:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "accountRepay": {
      "deny_if": [
        {
          "conditions": [],
          "on_deny": "Requires human approval."
        }
      ]
    }
  }
}

Any call to accountRepay is blocked until a human approves it. The rest of the server keeps working.
