Parameters from the server's own tool schema.

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "lookup_qr_code",
    "arguments": {}
  }
}
```

## Why lookup_qr_code is rated Critical

Although the tool's primary function (generating a QR code data URL) is a Read/Execute operation, every call incurs a real financial transaction in USDC on Base. Per the severity rules, Financial is the most severe applicable category and takes precedence. Severity is medium because the per-call cost is small but repeated or bulk misuse could accumulate meaningful charges.

From the tool's own definition: "Cost: $0.005–$0.05 USDC on Base per call. The server description states 'Pay-per-call' with 'x402 + USDC on Base', meaning each invocation commits a micropayment."

## Use case

AI agents use lookup_qr_code to commit financial operations through GoCreative Agent API, usually the final step of a payment, billing, or trading workflow. A call moves real money.

## Recommended policy (PolicyLayer)

Verdict: **Approval-gated**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches GoCreative Agent API:

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