linear_addIssueLabel · Linear MCP Server MCP: Risk & Policy

WHAT IT DOES

What linear_addIssueLabel does on Linear MCP Server

AI agents use linear_addIssueLabel 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_addIssueLabel needs a policy

Adding a label to an issue is a metadata modification that creates a new association but does not delete data and can be undone (label can be removed). It falls under Write category rather than Read (modifies state) or Destructive (reversible). Severity is medium because label manipulation could affect workflow categorization or visibility, but impact is localized to a single issue's metadata and fully reversible.

From the tool's definition Tool name 'linear_addIssueLabel' and description 'Add a label to an issue in Linear' indicate modification of issue metadata. This is a reversible write operation that changes existing issue state by adding an attribute.
