This tool retrieves NFT ownership data from the XRP Ledger. It is a read-only operation that queries existing data without modifying, deleting, executing code, or committing financial transactions. The blast radius is minimal—an AI agent using this tool can only view NFT holdings of a specified account, not alter them or trigger external operations.

From the tool's definition Tool name 'get_account_nfts' and description 'Get the NFTs owned by an XRP Ledger account' indicate a query/retrieval operation with no data modification or state-changing side effects.

POLICY

How to control get_account_nfts

PolicyLayer is an MCP gateway — it sits between your AI agents and XRPL MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_account_nfts:

policy.json

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

get_account_nfts 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 XRPL 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.
