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

```json
{
  "jsonrpc": "2.0",

  "method": "tools/call",
  "params": {
    "name": "get_nft_metadata",
    "arguments": {}
  }

## Why get_nft_metadata is rated Low

The verb 'get' combined with 'nft_metadata' strongly indicates a read-only query operation. Metadata retrieval does not modify, delete, execute code, or commit financial transactions. While the description is empty (lowering confidence slightly), the tool name itself provides sufficient evidence for classification as a Read operation.

From the tool's own definition: "Tool name 'get_nft_metadata' indicates retrieval of NFT metadata. No description provided, but the naming pattern and context of a wallet MCP server suggest this is a query operation that retrieves immutable blockchain data about NFTs without modifying state."

## Use case

AI agents call get_nft_metadata 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.

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_nft_metadata": {}
  }
}
```
