Manage field groups, register custom post types and taxonomies, create relationships, read/write meta values.
Meta Box registers post types, taxonomies, field groups and relationships in code-shaped configuration. Describing that structure is exactly what a language model is good at.
List every group with its fields, then define new ones against the post types you name.
Register both without writing a register_post_type() call by hand.
Create Meta Box relationships between post types, users and terms.
Read and write meta values through Meta Box, so field types are respected.
Scoped tokens and draft-mode keep large edits under control.
No exports, no SQL, no brittle scripts — just protocol.
Ask in plain language and the Meta Box integration turns it into typed calls — field groups, post types, taxonomies and relationships.
Turn a brief into post types, taxonomies and field groups in one pass.
Populate a field across an entire post type at once.
Find posts with empty or inconsistent fields and fix them in place.
Chain Meta Box actions into multi-step agent workflows.
The NibWP Meta Box integration exposes Meta Box to any MCP-compatible AI agent — Claude, Cursor, Claude Code and others. Field groups, post types, taxonomies and relationships become typed tool calls.
Meta Box describes a content model as configuration, which is precisely the kind of work that is tedious by hand and fast to describe in a sentence. An agent can scaffold a whole model — post types, taxonomies, the field groups that hang off them, and the relationships between them — then fill it with real content.
Reading and writing meta goes through Meta Box rather than raw post meta, so field types, clones and grouped fields are stored in the shape the plugin expects.
| Tool | Type | What it does |
|---|---|---|
| list_field_groups | read | Every Meta Box field group with its fields and locations. |
| create_field_group | write | Define a field group and its fields. |
| register_post_type | write | Register a custom post type with its labels and supports. |
| register_taxonomy | write | Register a taxonomy and bind it to post types. |
| create_relationship | write | Relate post types, users or terms to each other. |
| get_values | read | Read meta values through Meta Box, with field types respected. |
| update_values | write | Write meta values through Meta Box rather than raw post meta. |
Yes. Once Meta Box is active, NibWP detects it and its abilities go live instantly — no configuration needed.
Field groups, post types, taxonomies and relationships are covered. Anything registered through Meta Box is read from your install rather than assumed.
Yes. Values are read and written through Meta Box, so field types, clones and groups behave as they do in the admin.
No. Creating a group adds one; updating values touches only the fields you name. Destructive changes are never implied by a create call.
Activate the integration and it's live on your MCP endpoint instantly.
