## Why wallet_listOutputs is rated Low

This tool retrieves and lists blockchain outputs (UTXOs) from a wallet, which is a read-only operation. It does not spend, transfer, or modify any funds—it only queries the state of available outputs. While it reveals financial information (spendable funds), it causes no side effects and does not commit any financial transactions.

From the tool's own definition: "Tool name 'wallet_listOutputs' and description 'Lists spendable outputs in a basket, optionally filtered by tags' indicates a query/retrieval operation with no modification or spending of funds."

## Use case

AI agents call wallet_listOutputs to retrieve information from Bitcoin SV MCP Server 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 Bitcoin SV MCP Server:

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