Delete a field from a table
AI agents call delete_field to permanently remove resources in Airtable MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deleting a field from a table is irreversible and destroys the column and all its associated data across all records in that table. This cannot be undone without a backup restore, making it a destructive operation. While not as severe as deleting an entire base, field deletion permanently eliminates data at scale and affects the integrity of the table structure.
From the tool's definition Tool name is 'delete_field' and description states 'Delete a field from a table'. The verb 'delete' indicates irreversible removal of data structure.
