Delete a comment.
AI agents call delete_comment to permanently remove resources in Notion MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes comment data from Notion, which cannot be undone. While the blast radius is scoped to individual comments (not the entire database), deletion is irreversible and represents a destructive action. Severity is high rather than critical because impact is limited to comment artifacts rather than core data structures like pages or databases.
From the tool's definition Tool name is 'delete_comment' with description 'Delete a comment.' The verb 'delete' indicates irreversible removal of data.
