Delete a work item type by ID.
AI agents call delete_work_item_type to permanently remove resources in Plane — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes a work item type from the Plane project management system. Deleting a work item type is an irreversible action that could affect multiple work items and project workflows. If an AI agent mistakenly deletes a critical work item type (e.g., 'Bug', 'Task', 'Feature'), it would cause significant disruption and data loss that cannot be easily recovered.
From the tool's definition The tool name explicitly contains 'delete' and the description states 'Delete a work item type by ID.' Deletion operations are inherently irreversible and destructive.
Attacks that exploit this kind of access
Delete a work item type by ID. It is categorised as a Destructive tool in the Plane MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Plane MCP server in PolicyLayer and add a rule for delete_work_item_type: 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 Plane. Nothing to install.
delete_work_item_type 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_work_item_type 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_work_item_type. 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_work_item_type is provided by the Plane MCP server (@makeplane/plane-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
