Delete a task list (top-level container) from Microsoft Todo. This will remove the list and all tasks within it.
AI agents call delete-task-list to permanently remove resources in Microsoft Todo Safe — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes data (a task list and all its tasks) without the ability to reverse the operation. Although the server emphasizes 'backup, preview, confirmation, and audit safeguards' in its description, the tool itself performs irreversible deletion. Destructive is more severe than Write (which is reversible) and represents the most appropriate category.
From the tool's definition Tool description explicitly states 'Delete a task list' and 'will remove the list and all tasks within it.' The word 'Delete' combined with the irreversible removal of both the container and all contained data confirms destructive action.
Attacks that exploit this kind of access
Delete a task list (top-level container) from Microsoft Todo. This will remove the list and all tasks within it. It is categorised as a Destructive tool in the Microsoft Todo Safe MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Microsoft Todo Safe MCP server in PolicyLayer and add a rule for delete-task-list: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Microsoft Todo Safe. Nothing to install.
delete-task-list is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the delete-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 delete-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.
delete-task-list is provided by the Microsoft Todo Safe MCP server (saenai/microsoft-todo-safe-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
