## Why remove_subscribers_from_list is rated Critical

Removing subscribers from a list is a destructive operation in that it severs the association between subscribers and the list. While subscribers remain in the account, the list membership removal is not described as reversible through this tool, making it closer to Destructive than Write.

From the tool's own definition: "'Remove subscribers from a list' — removes list membership; 'only the list membership is removed' suggests partial reversibility, but the removal action itself is not explicitly undoable via this tool"

## Use case

AI agents call remove_subscribers_from_list to permanently remove resources in Sequenzy Mcp, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

## Recommended policy (PolicyLayer)

```json

  "version": "1",
