Read-onlyList all registered ACF field groups — keys, labels, types
Requires ACF or Secure Custom Fields (SCF). Field groups must have Show in REST API enabled in ACF settings.
Description
Before any ACF read or write operation, you need field keys — not field names — and wp_acf_list_field_groups is the discovery step that surfaces them. It returns every registered field group with keys, labels, and field types, giving your AI client the schema map it needs before calling any update tool. Easy MCP AI makes this the natural first step in ACF-driven workflows: an AI client like Cursor or Windsurf calls wp_acf_list_field_groups through Easy MCP AI, maps the field structure, then proceeds to read or update content — all without opening WordPress.
