Delete a label by ID.
AI agents call delete_label 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 labels. While the blast radius is scoped to a single label (not system-wide), deletion cannot be undone and permanently removes the label from the system. This is clearly a Destructive operation, which is more severe than Write.
From the tool's definition Tool name is 'delete_label' and description states 'Delete a label by ID' - uses the verb 'Delete' which is an irreversible operation that removes data.
Attacks that exploit this kind of access
Delete a label 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_label: 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_label 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_label 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_label. 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_label 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.
