## Why wallet_listCertificates is rated Low

This tool retrieves and displays certificate data based on filter parameters. It does not create, modify, delete, or execute any operations that would change blockchain state or trigger financial transactions. The operation is purely informational and read-only in nature, with minimal blast radius if misused.

From the tool's own definition: "Tool name 'wallet_listCertificates' and description 'Lists identity certificates filtered by certifiers and types' indicate a query/retrieval operation with no side effects. The word 'Lists' explicitly denotes a read-only action."

## Use case

AI agents call wallet_listCertificates 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",
