WHAT IT DOES

What create_cycle does on Plane

AI agents use create_cycle to create or update resources in Plane, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Plane environment.

RISK

Why create_cycle is rated Medium

This tool creates a new cycle (a project management construct, likely a time-boxed iteration or sprint) within a project. Creation is a Write operation—it adds data reversibly. Unlike destructive operations, a created cycle can be modified or deleted.

From the tool's definition Tool name 'create_cycle' and description 'Create a new cycle in a project' indicates a creation operation that adds a new entity to the project management system.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs create_cycle safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Plane, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For create_cycle, this is the rule to start with:

create_cycle Rate-limited

create_cycle stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about create_cycle

What does the create_cycle tool do? +

Create a new cycle in a project. It is categorised as a Write tool in the Plane MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on create_cycle? +

Register the Plane MCP server in PolicyLayer and add a rule for create_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.

What risk level is create_cycle? +

create_cycle is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit create_cycle? +

Yes. Add a rate_limit block to the create_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.

How do I block create_cycle completely? +

Set action: deny in the PolicyLayer policy for create_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.

What MCP server provides create_cycle? +

create_cycle is provided by the Plane MCP server (cmet7/plane-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
