Delete an annotation from a Google Analytics 4 property.
AI agents call ga4_admin_api_delete_annotation to permanently remove resources in Google Analytics 4 Admin MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deleting an annotation removes metadata that cannot be recovered without manual re-creation. While not as critical as deleting raw analytics data, annotations often document important analytical insights or business events tied to data interpretation. Once deleted, the annotation is permanently lost. This irreversible data removal qualifies as Destructive rather than Write (which is reversible).
From the tool's definition Tool name contains 'delete_annotation' and description states 'Delete an annotation from a Google Analytics 4 property.' The verb 'delete' indicates irreversible removal of data.
