原文外掛簡介
Seeb Abilities adds 100 new abilities to WordPress, so AI agents can write and edit posts, build pages block by block, manage patterns, templates, menus and users, moderate comments, audit your content and more, instead of only reading information about your site.
WordPress 6.9 introduced the Abilities API: a standard way for plugins to describe what they can do, with typed inputs and outputs and permission checks, so that AI assistants, Model Context Protocol (MCP) clients and automation tools can discover and use them. Core registers only a few read-only abilities, such as site and environment information. Seeb Abilities fills the gap with the everyday content-management tasks.
Seeb Abilities is best used with the free MCP Adapter plugin, which turns these abilities into MCP tools that Claude, ChatGPT, Cursor, VS Code and other MCP clients can use directly.
Every ability:
Uses WordPress’s own functions (wp_insert_post(), wp_update_post(), wp_set_object_terms() and so on), so hooks, caches, revisions and other plugins behave exactly as they do in the admin.
Checks the current user’s capabilities for that specific object. An agent connected as an Author can edit their own posts, but not someone else’s and not the site settings.
Declares input and output schemas, and annotations (read-only, destructive, idempotent) that clients use to decide when to ask before acting.
Is available through the WordPress REST API (/wp-json/wp-abilities/v1/) and, when the MCP Adapter plugin is active, as MCP tools.
100 new abilities

Safe by default
Deleting moves to the trash. Permanent deletion needs force: true and is marked as destructive.
Settings can only be read and changed from a fixed allowlist. Arbitrary options are never touched.
Protected post meta (keys starting with _) cannot be written.
Password-protected content is only returned to users who can edit it.
No ability runs PHP or SQL, edits files, or installs, updates or activates plugins.
Users are created with a random password that is never returned; they set their own via email. Roles can only be given if the connected user may assign them, and nobody can change their own role.
Find and replace runs as a dry run unless told otherwise, saves a revision of each changed post, and skips posts whose block structure would break.
Query results are paginated with a maximum page size.
Site owners can turn off any ability, or a whole category, under Settings → Seeb Abilities.
For developers
Filter seeb_abilities_ability_args to change an ability’s arguments before it is registered.
