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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "wallet_proveCertificate",
    "arguments": {}
  }
}
```

## Why wallet_proveCertificate is rated High

Proving certificate fields to a verifier involves executing a cryptographic proof operation against the BSV blockchain/wallet system. This is not purely reading data (it generates and submits a proof to an external verifier), nor does it move funds or destructively alter data. It falls under Execute as it triggers an external operation whose effects depend on the certificate fields and verifier arguments.

From the tool's own definition: "'Proves select fields of a certificate to a verifier' — triggers an external cryptographic operation that interacts with wallet/blockchain infrastructure"

## Use case

AI agents invoke wallet_proveCertificate to trigger actions in Bitcoin SV MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

## Recommended policy (PolicyLayer)
