Delete a project and all its tasks.
AI agents call delete_project to permanently remove resources in Todoist MCP Helper — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes a project and all associated tasks, which cannot be undone. This is irreversible data loss, making it Destructive rather than Write. The blast radius is significant because a single misuse could erase an entire project's worth of work. High severity is appropriate given the irreversibility and potential loss of user data.
From the tool's definition Tool name is 'delete_project' and description explicitly states 'Delete a project and all its tasks.' The word 'Delete' combined with 'all its tasks' indicates irreversible removal of data.
Attacks that exploit this kind of access
Delete a project and all its tasks. It is categorised as a Destructive tool in the Todoist MCP Helper MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Todoist MCP Helper MCP server in PolicyLayer and add a rule for delete_project: 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 MCP Helper. Nothing to install.
delete_project 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_project 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_project. 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_project is provided by the Todoist MCP Helper MCP server (littlepeter52012/todoist-mcp-helper). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
