Plugin: Advanced Custom Fields Advanced Custom Fields

Update one or more ACF field values on a post/page

Requires ACF or Secure Custom Fields (SCF). Field groups must have Show in REST API enabled in ACF settings.

Description

Writing to ACF-powered content — updating property prices, flipping feature flags, populating spec sheets — is what wp_acf_update_fields does for posts and pages across any post type. Field keys (e.g. field_abc123) are required rather than field names, so run wp_acf_list_field_groups first to get them; Easy MCP AI makes that two-step workflow seamless within a single AI client session. With Easy MCP AI's 162-tool library running over pure PHP, clients like Claude Desktop or ChatGPT can update multiple ACF fields on multiple posts in one conversation without any admin panel involvement.
