Delete a comment
AI agents call delete_comment to permanently remove resources in Todoist — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deleting a comment is an irreversible action that removes data from the Todoist system. While the blast radius is limited to a single comment (not catastrophic), it cannot be undone without manual intervention or API recovery. This qualifies as Destructive rather than Write (which covers reversible modifications).
From the tool's definition Tool name 'delete_comment' and description 'Delete a comment' indicate irreversible deletion of data. The verb 'delete' is characteristic of destructive operations that cannot be undone.
Attacks that exploit this kind of access
Delete a comment. It is categorised as a Destructive tool in the Todoist MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Todoist MCP server in PolicyLayer and add a rule for delete_comment: 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 Todoist. Nothing to install.
delete_comment 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_comment 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_comment. 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_comment is provided by the Todoist MCP server (sjvadrevu/todoist-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
