## Why add_ab_test_variant is rated Medium

This tool creates or modifies A/B test variants within marketing campaigns and sequences. While it doesn't delete data (not Destructive) or execute arbitrary code (not Execute), it does modify marketing campaign configurations reversibly. The requirement for confirmation on live sequences and the ability to add variants to active sequences suggest significant operational impact.

From the tool's own definition: "'Add a variant to a draft campaign or sequence A/B test' - creates a new test variant that modifies campaign/sequence structure."

## Use case

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