What delete_task_list does on VaultAssist
AI agents call delete_task_list to permanently remove resources in VaultAssist, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why delete_task_list is rated Critical
This tool permanently removes a task list and cascades deletion to all contained tasks. The operation is irreversible and represents data loss. Although scoped to a single user's task list (multi-user isolation mitigates blast radius), the destructive nature and inability to undo the action place it in the Destructive category rather than Write.
From the tool's definition 'Delete a task list' with explicit note 'This will also delete all tasks in the list' — irreversibly removes data and all associated child records without recovery option.
Attacks that exploit this kind of access
The rule that runs delete_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 delete_task_list, this is the rule to start with:
delete_task_list is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect VaultAssist, apply this rule, and every delete_task_list call is checked against it from then on.
