Acf

This connects Claude to Advanced Custom Fields, the WordPress plugin for adding structured data to posts and pages. You get programmatic access to custom field groups and entries without touching the WordPress admin or writing API boilerplate. The Membrane integration handles auth and credential refresh automatically, so you can query and update ACF data through natural language action discovery or direct API proxy requests. Best for WordPress developers who want to automate content workflows or build tooling around custom fields. Free tier supported, which is nice since most ACF work happens in development environments anyway.
