WHAT IT DOES

What update_cycle does on Plane

AI agents use update_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 update_cycle is rated Medium

The tool performs an update operation on cycle entities within a project management system. Updates are reversible modifications (Write category) rather than irreversible deletions (Destructive). The severity is medium because misuse could disrupt project timelines and team coordination, but changes can typically be reverted.

From the tool's definition Tool name 'update_cycle' combined with server description stating 'full CRUD operations' and presence of sibling tools like 'create_cycle' and 'delete_cycle' indicates this modifies cycle data reversibly.

RECOMMENDED RULE

The rule that runs update_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 update_cycle, this is the rule to start with:

update_cycle Rate-limited

update_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.
