THE RISK

Low Risk

Why getNFTs needs a policy

This tool retrieves and displays existing NFT data associated with a wallet—a read-only operation. It fetches collection information and images but does not create, modify, delete, or execute any transactions or code. While the server handles financial operations (trading, wallet management), this specific tool merely queries blockchain data about NFT ownership.

From the tool's definition Tool name 'getNFTs' and description 'Get NFT holdings for a wallet address including collection information and images' indicate a query operation that retrieves data without modification or side effects.

POLICY

How to control getNFTs

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

policy.json

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

getNFTs 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 Boosty MCP DeFi Platform — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
