## Why delete_custom_field is rated Critical

This tool removes custom fields from the GoHighLevel CRM system. Deletion of custom fields is irreversible and could cascade impact (data loss, broken workflows, form dependencies). While not system-critical like deleting all contacts, it represents permanent data structure modification. High severity due to potential business process disruption and data loss if triggered inappropriately by an AI agent.

From the tool's own definition: "Tool name 'delete_custom_field' with description 'Delete a custom field' indicates irreversible deletion of data. The verb 'delete' is explicitly destructive."

## Use case

AI agents call 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)

Verdict: **Hidden**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches GoHighLevel MCP Server:

```json
{
  "version": "1",
  "default": "deny",
  "hide": [
    "delete_custom_field"
  ]
}
```
