## Why verify-nft-ownership is rated Low

This tool performs a read-only verification of NFT ownership on the XRP Ledger. It retrieves and checks data (ownership status) but produces no side effects, no state changes, and no irreversible actions. It falls squarely within the Read category. Severity is low because misuse would only expose or confirm existing public ledger data about NFT ownership, with no financial impact or destructive capability.

From the tool's own definition: "Tool name 'verify-nft-ownership' and description 'Verify if an address owns a specific NFT' indicate a query operation that checks ownership status without modifying data, triggering transactions, or executing arbitrary code."

## Use case

AI agents call verify-nft-ownership to retrieve information from Xrpl mcp without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Xrpl mcp:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "verify-nft-ownership": {}
  }
}
```
