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

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

## Why taproot_get_pubkey is rated Low

This tool derives and returns a public key, which is a read-only operation with no side effects. Public keys are meant to be publicly known and exposing them carries minimal security risk. The operation is informational only—it does not modify wallet state, execute transactions, or perform destructive actions.

From the tool's own definition: "Tool name 'taproot_get_pubkey' and description 'Derive the x-only Taproot public key' indicates retrieval of a cryptographic public key from the wallet."

## Use case

AI agents call taproot_get_pubkey to retrieve information from Aibtc 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 Aibtc:

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