Permanently delete a plan and all its tasks.
AI agents call delete_plan to permanently remove resources in Todos — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly deletes data (a plan and associated tasks) with no undo capability. This is a core characteristic of the Destructive category. The scope (deleting an entire plan and all its tasks) creates a significant blast radius if misused by an AI agent, warranting high severity. Confidence is high because the description explicitly confirms permanent deletion.
From the tool's definition Tool name is 'delete_plan' and description states it 'Permanently delete a plan and all its tasks' — uses 'Permanently delete', indicating irreversible data destruction.
Attacks that exploit this kind of access
Permanently delete a plan and all its tasks. It is categorised as a Destructive tool in the Todos MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Todos MCP server in PolicyLayer and add a rule for delete_plan: 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 Todos. Nothing to install.
delete_plan 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_plan 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_plan. 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_plan is provided by the Todos MCP server (@hasna/todos). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
