Create a new custom field folder for organizing fields within an object.
AI agents use ghl_create_custom_field_folder to create or update resources in GoHighLevel MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your GoHighLevel MCP Server environment.
This tool creates a new data structure (a custom field folder) within a CRM system. Creation is a reversible write operation — the folder can be deleted or modified later. It does not execute arbitrary code, delete irreversibly, or move money, so it falls into the Write category.
From the tool's definition Tool description states 'Create a new custom field folder' — the verb 'create' and the action of organizing fields indicates data creation/modification rather than retrieval or deletion.

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 ghl_create_custom_field_folder:
{
"version": "1",
"default": "deny",
"tools": {
"ghl_create_custom_field_folder": {
"limits": [
{
"counter": "ghl_create_custom_field_folder_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}ghl_create_custom_field_folder stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
