Delete a cycle by ID.
AI agents call delete_cycle 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 deletes a cycle resource by its ID, permanently removing it from the system. This is a destructive action that cannot be undone, matching the definition of the Destructive category. The severity is high because deleting a cycle likely cascades to associated work items and project data, representing significant blast radius if misused by an AI agent.
From the tool's definition Tool name 'delete_cycle' with description 'Delete a cycle by ID' explicitly performs deletion, which is an irreversible operation.
Attacks that exploit this kind of access
Delete a cycle 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_cycle: 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_cycle 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_cycle 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_cycle. 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_cycle 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.
