Get a custom field or folder by its ID. Supports custom objects and company (business) fields.
AI agents call ghl_get_custom_field_by_id to retrieve information from GoHighLevel MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves field definitions and metadata by ID, with no indication of side effects, modification, deletion, or execution capabilities. It is analogous to fetching configuration or schema information, which is a read-only operation. The context of a CRM system containing sensitive data suggests data could be returned, but the tool itself only retrieves what already exists without altering it.
From the tool's definition 'Get a custom field or folder by its ID' describes retrieval of field metadata without modification. The description indicates a query operation that fetches configuration/schema data about custom fields or folders.
