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.

ACF

ACF is a WordPress plugin that allows developers to add custom fields to WordPress content. It's used by WordPress developers and website builders to create more flexible and dynamic websites. It simplifies content management by allowing users to easily input structured data.

Use action names and parameters as needed.

Working with ACF

This skill uses the Membrane CLI to interact with ACF. Membrane handles authentication and credentials refresh automatically — so you can focus on the integration logic rather than auth plumbing.

Install the CLI

Install the Membrane CLI so you can run membrane from the terminal:

npm install -g @membranehq/cli@latest

Authentication

membrane login --tenant --clientName=<agentType>

This will either open a browser for authentication or print an authorization URL to the console, depending on whether interactive mode is available.
