linear_link_issues · Linearapp MCP: Risk & Policy

WHAT IT DOES

What linear_link_issues does on Linearapp

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

WHY IT NEEDS A POLICY

Why linear_link_issues needs a policy

Creating relationships between issues is a reversible modification operation that alters metadata/structure but does not delete data or execute arbitrary code. This falls under Write category. Severity is medium because unauthorized linking could confuse issue tracking and project management, but the effect is bounded to relationship metadata and easily correctable.

From the tool's definition Tool name 'linear_link_issues' and description 'Create a relationship between issues in Linear' indicate the tool modifies issue state by establishing or changing relationships between issues.
