WHAT IT DOES

What add_ab_test_variant does on Sequenzy Mcp

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.

RISK

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 definition "Add a variant to a draft campaign or sequence A/B test" - creates a new test variant that modifies campaign/sequence structure.

RECOMMENDED RULE

The rule that runs add_ab_test_variant safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Sequenzy Mcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For add_ab_test_variant, this is the rule to start with:

add_ab_test_variant Rate-limited

add_ab_test_variant 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.
