THE RISK

Critical Risk

Why SmallAssetQuote needs a policy

This tool initiates a financial conversion process (currency/asset conversion on a crypto exchange) by applying for a batch conversion quote. While it only returns a quote (not yet executing the trade), it is the first step in committing to a financial transaction and is categorized under 'Convert' permissions. The quote ID returned can be used to execute the actual conversion.

From the tool's definition Apply for batch conversion quote for a small asset list. Returns quote ID and per-coin conversion details. API key permission: Convert

POLICY

How to control SmallAssetQuote

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 SmallAssetQuote:

policy.json

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

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