Delete a draft campaign
AI agents call delete_campaign to permanently remove resources in Campaign Monitor MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool permanently removes a campaign, which cannot be undone. Although it specifies 'draft' campaigns (limiting the business impact compared to deleting sent campaigns), deletion is inherently destructive and irreversible. This warrants the Destructive category with high severity due to the potential loss of campaign work and configuration, even if only affecting drafts.
From the tool's definition Tool name is 'delete_campaign' and description states 'Delete a draft campaign'. The verb 'delete' indicates irreversible removal of data.
