What create_task_list does on VaultAssist
AI agents use create_task_list to create or update resources in VaultAssist, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your VaultAssist environment.
Why create_task_list is rated Medium
This tool creates new data (a task list) without permanent destruction or financial impact. It is a Write operation because it modifies state reversibly. Severity is medium rather than low because creating task lists in a shared workspace could affect other users' workflows, and an AI agent could spam task list creation. Confidence is high given the clear description and typical Google Tasks API behavior.
From the tool's definition Tool name 'create_task_list' and description 'Create a new task list' indicate data creation. The action is reversible (task lists can be deleted), and the scope is limited to a user's Tasks workspace within Google Workspace.
Attacks that exploit this kind of access
The rule that runs create_task_list 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 create_task_list, this is the rule to start with:
create_task_list stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect VaultAssist, apply this rule, and every create_task_list call is checked against it from then on.

create_task_list is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the create_task_list rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for create_task_list. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
