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

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

## Why list_tokens is rated Low

This tool retrieves or queries information about registered tokens, optionally filtered by VM type. It performs no data creation, modification, deletion, code execution, or financial transactions. It is a straightforward read operation with minimal blast radius if misused by an AI agent, as it only exposes token metadata.

From the tool's own definition: "Tool name 'list_tokens' and description 'List registered tokens with optional VM type filter' indicate a retrieval operation with no side effects. The verb 'list' is a classic read operation that queries data without modification."

## Use case

AI agents call list_tokens to retrieve information from Tenzro Ledger MCP 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 Tenzro Ledger MCP:

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