Delete a TickTick project by ID
AI agents call delete_project to permanently remove resources in TickTick MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deletion of a project is a destructive action that cannot be undone—it removes an entire project and likely all associated tasks. This is more severe than individual task deletion (delete_task) because projects typically contain multiple items and represent organizational structures. The high severity reflects the blast radius: an agent error could eliminate substantial user work.
From the tool's definition Tool name is 'delete_project' and description states 'Delete a TickTick project by ID'. The verb 'delete' combined with project-level scope indicates irreversible removal of data.
Attacks that exploit this kind of access
Delete a TickTick project by ID. It is categorised as a Destructive tool in the TickTick MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the TickTick MCP Server 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 TickTick MCP Server. 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 TickTick MCP Server MCP server (k-wakamatsu-tms/ticktick-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
