delete_location_custom_field

THE RISK

Critical Risk

The tool performs an irreversible deletion of data (a custom field). This is a destructive operation that cannot be reversed. While the blast radius may be limited to a single custom field rather than an entire location, the deletion is permanent and data loss is the outcome.

HOW TO CONTROL DELETE_LOCATION_CUSTOM_FIELD

PolicyLayer is an MCP gateway — it sits between your AI agents and GoHighLevel MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for delete_location_custom_field:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "delete_location_custom_field"
  ]
}

delete_location_custom_field disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register GoHighLevel MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
