WHAT IT DOES

What machines_list does on Todos

AI agents call machines_list to retrieve information from Todos without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why machines_list is rated Low

This tool retrieves and displays a list of registered machines. It is a read-only operation with no capability to modify, execute, or delete data. The low severity reflects minimal risk even if misused—an AI agent could only enumerate machines, not interact with them harmfully.

From the tool's definition Tool name 'machines_list' and description 'List all registered machines' indicate a query operation that retrieves information without side effects.

RECOMMENDED RULE

The rule that runs machines_list safely

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

machines_list Allowed

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

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

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

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