WHAT IT DOES

What list_tokens does on Tenzro Ledger MCP

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.

RISK

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 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.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs list_tokens safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Tenzro Ledger MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For list_tokens, this is the rule to start with:

list_tokens Allowed

list_tokens is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

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

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Tenzro Ledger MCP, apply this rule, and every list_tokens call is checked against it from then on.
