Why querySubMemberDepositRecords needs a policy

This tool retrieves deposit records for a sub-account, which is a read-only operation with no side effects. However, the sensitivity is elevated to medium severity because: (1) it accesses financial transaction history that could reveal account activity, holdings, and user patterns; (2) it operates on a sub-account via main UID credentials, indicating privileged access; (3) misuse by an AI agent could leak sensitive…

From the tool's definition Tool name 'querySubMemberDepositRecords' and description 'Query on-chain deposit records' indicate data retrieval. The phrase 'Query' and 'deposit records' confirm a read operation that retrieves historical transaction data without modification.

How to control querySubMemberDepositRecords

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 querySubMemberDepositRecords:

policy.json

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

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

Create a free account and register Bybit MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
