WHAT IT DOES

What linear_addIssueToCycle does on Linear MCP Server

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

WHY IT NEEDS A POLICY

Why linear_addIssueToCycle needs a policy

This tool creates or modifies a relationship between an issue and a cycle within Linear's project management system. The action is reversible (the issue can be removed from the cycle), and it does not delete data or execute arbitrary code. It falls under the Write category as it modifies project state without destructive or executable side effects.

From the tool's definition Tool name 'linear_addIssueToCycle' and description 'Add an issue to a cycle' indicate a modification operation that associates an issue with a project cycle, changing issue metadata reversibly.
