Delete a call and all associated data including recordings and transcripts.
AI agents call retell_delete_call to permanently remove resources in Retell AI MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly deletes data that cannot be recovered or undone. Deletion of call records, recordings, and transcripts represents permanent data loss with significant compliance and operational implications.
From the tool's definition Tool name contains 'delete' and description explicitly states 'Delete a call and all associated data including recordings and transcripts' — permanent removal of multiple data types (calls, recordings, transcripts).
