About
Get and update Meta Box custom fields to the WordPress REST API responses.
What It Does
MB Rest API extends the WordPress REST API so that custom fields created with the Meta Box plugin appear in API responses and can be updated through API requests. In practice, it lets headless frontends, mobile apps, and other external clients read and write Meta Box field data without needing direct database access. Without it, those custom fields stay invisible to the REST API by default.
Who It's For
This plugin is for developers building headless WordPress sites, mobile apps, or decoupled frontends that already rely on Meta Box for custom fields and need that data exposed through REST endpoints. It is most useful on projects where Meta Box is the chosen field framework and the team needs read/write access to field values from outside WordPress. Smaller sites with no custom field needs or no headless setup will get little value from it.
Who Should Skip It
Anyone not already using Meta Box to manage custom fields should skip this plugin, as it provides no benefit without that dependency. Sites that do not consume the REST API externally have no reason to add it.
The Bottom Line
MB Rest API is a focused, well-maintained bridge for a specific stack: Meta Box plus a headless or external client. Its overall quality score of 60.93/100 is held back by a tiny install count and zero user ratings, but the maintenance and compatibility signals are strong. Use it if you are already committed to Meta Box and need REST access; otherwise, ACF or Pods will give you broader community support out of the box.

Pick Pods if you want an all-in-one custom content solution that already exposes its fields to the REST API without an add-on.
Pick Admin Columns if your goal is to display and edit custom fields in the WordPress admin rather than expose them through the REST API.
