WHAT IT DOES

What list_task_lists does on VaultAssist

AI agents call list_task_lists to retrieve information from VaultAssist 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_task_lists is rated Low

This tool retrieves task list metadata for the authenticated user. It performs a read-only query operation with no side effects, no data modification, and no execution of arbitrary commands. The blast radius of misuse is minimal — an attacker could enumerate a user's tasks but cannot modify, delete, or exfiltrate them through this tool alone.

From the tool's definition 'List all task lists for the user' — a retrieval operation that queries task data without modification, deletion, or execution of external code.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs list_task_lists safely

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

list_task_lists Allowed

list_task_lists 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_task_lists": {}
  }
}

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

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