manage_sequences · Kit MCP: Risk & Policy

WHAT IT DOES

What manage_sequences does on Kit

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

WHY IT NEEDS A POLICY

Why manage_sequences needs a policy

Enrolling subscribers in email sequences creates new associations and modifies subscriber state. While the operation is reversible (subscribers can be unenrolled), it affects subscriber data and can trigger automated email campaigns. The 'list' and 'list_subscribers' actions are Read operations, but the most severe capability is Write (add_subscriber).

From the tool's definition Tool description states 'enroll a subscriber' and action 'add_subscriber', which creates or modifies subscriber enrollment state in email sequences. This is a reversible write operation.

Verdict

manage_sequences Rate-limited

manage_sequences 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.
