Delete a label from a project.
AI agents call plane-label-delete 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.
The tool performs an irreversible deletion operation on project metadata (labels). While not as critical as deleting issues or pages, label deletion cannot be undone and affects project organization. Misuse by an AI agent could disrupt project workflows by removing classification labels that issues depend on.
From the tool's definition Tool name contains 'delete' and description states 'Delete a label from a project' — this irreversibly removes data.
Attacks that exploit this kind of access
Delete a label from a project. 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 plane-label-delete: 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.
plane-label-delete 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 plane-label-delete 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 plane-label-delete. 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.
plane-label-delete is provided by the Plane MCP server (philipvanlewis/plane-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
