WHAT IT DOES

What create_list does on Sequenzy Mcp

AI agents use create_list 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 create_list is rated Medium

Creating a new list is a write operation that adds a new entity to the system. It is reversible (the list can be deleted), so it does not qualify as Destructive. The blast radius is medium because miscreation of lists could disrupt email marketing workflows, but the impact is limited to data organization rather than financial transactions or irreversible data loss. This fits squarely in the Write category.

From the tool's definition Tool name is 'create_list' and description states 'Create a new subscriber list' — this creates a new data structure within the email marketing system.

RECOMMENDED RULE

The rule that runs create_list 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 create_list, this is the rule to start with:

create_list Rate-limited

create_list 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.
