[CUSTOM] Calls the Marketo REST API directly (not Adobe's native MCP).
AI agents call custom_discard_landing_page_template_draft to permanently remove resources in Marketo MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The verb 'discard' typically means to permanently remove or abandon without recovery. In a marketing automation context like Marketo, discarding a draft template state is an irreversible operation that cannot be undone—the draft changes are lost. This fits the Destructive category (irreversibly deletes or overwrites data). While not deleting the template entirely, it destroys the draft version's work.
From the tool's definition Tool name includes 'discard', which indicates removal or deletion. 'draft' suggests the action targets a specific version. Combined with 'landing_page_template', this tool appears to irreversibly discard a draft state of a template asset.
