WHAT IT DOES

What list_items does on Ha Nexus Agent

AI agents call list_items to retrieve information from Ha Nexus Agent 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_items is rated Low

This tool queries and retrieves todo list items without creating, modifying, deleting, or executing operations. It has no side effects and minimal blast radius even if misused by an AI agent—at worst, it exposes todo list contents the user already has access to.

From the tool's definition Tool name 'list_items' and description 'List items in a todo list' indicate data retrieval with no modification capability. The WebSocket endpoint reference 'todo/item/list' follows a standard read-only list pattern.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs list_items safely

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

list_items Allowed

list_items 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_items": {}
  }
}

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

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