## Why ghl_delete_custom_field is rated Critical

This tool irreversibly deletes custom fields and associated data with no undo capability. It affects data structures that may be relied upon across contacts and workflows in the CRM. While not affecting financial records directly, the permanent loss of custom field data across potentially many records makes this a high-severity destructive action.

From the tool's own definition: "'Delete a custom field by ID. This will permanently remove the field and its data.' - the use of 'permanently remove' and 'delete' indicates irreversible deletion of data."

## Use case

AI agents call ghl_delete_custom_field to permanently remove resources in GoHighLevel MCP Server, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

## Recommended policy (PolicyLayer)
