WHAT IT DOES

What list_nfts does on Waiaas

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

RISK

Why list_nfts is rated Low

Despite the empty description creating some uncertainty, the tool name 'list_nfts' maps to the Read category—it retrieves or queries data without side effects. In a wallet context, listing NFTs is analogous to viewing account holdings, with no capacity to transfer, burn, or modify assets.

From the tool's definition Tool name 'list_nfts' indicates a retrieval operation that queries NFT holdings or metadata. The 'list' prefix strongly suggests a non-destructive read operation consistent with blockchain data queries.

RECOMMENDED RULE

The rule that runs list_nfts safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Waiaas, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For list_nfts, this is the rule to start with:

list_nfts Allowed

list_nfts is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

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

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Waiaas, apply this rule, and every list_nfts call is checked against it from then on.
