Enable Abilities for MCP
Enable Abilities for MCP gives you full control over which WordPress Abilities are available to AI assistants through the MCP (Model Context Protocol) Adapter. WordPress 6.9 introduced the Abilities API, allowing external tools to discover and execute actions on your site. This plugin extends that functionality by registering a comprehensive set of content management abilities and providing a simple admin interface to toggle each one on or off. Connect from claude.ai with just a URL Since version 2.1 the plugin ships an embedded OAuth 2.1 server built for claude.ai custom connectors. Add your site in claude.ai → Settings → Connectors, log in with your WordPress user, approve the consent screen — connected. No Client ID, no Application Password, no local configuration. Works from the claude.ai web app, mobile apps, and Claude Desktop Each team member authenticates with their own WordPress account and role — a subscriber can never do what only an editor should Every ability execution lands in the activity log under the real user’s name Works on single sites, subdirectory installs, and multisite networks (network-activate so the main site serves the OAuth discovery documents for every subsite) Prefer tokens? Application Passwords (per-user) and a single-admin Bearer token connect Claude Desktop / Claude Code, OpenAI Codex CLI, and Google Antigravity — the Connection tab generates ready-to-paste configuration for each client, and fills in your credentials automatically. Features 91 abilities organized in 18 categories: Core, Read, Write, SEO (Rank Math), SEO (SEOPress), SEO (Yoast), Navigation Menus, Utility, Multilanguage, Custom Post Types, WooCommerce, The Events Calendar, Code Snippets, JetEngine Options Pages, Elementor, LearnDash, Tutor LMS, and AI Agent Readiness (llms.txt) WooCommerce integration — dedicated abilities to manage products, orders, and customers using the native WooCommerce API (HPOS-compatible, formally declared) The Events Calendar integration — list, get, create, and update events with venue, organizer, and date filters claude.ai OAuth custom connector — connect from claude.ai (web, mobile, or desktop) with zero local setup: an embedded OAuth 2.1 server with Client ID Metadata Document (CIMD) support lets each user log in with their own WordPress account and role Admin dashboard with toggle switches for each ability Per-ability control — expose only what you need Third-party ability control — abilities registered by other MCP-ready plugins (e.g. Fluent Forms) appear in the same dashboard, grouped by plugin, with the same per-ability toggles; disabling one removes it from every MCP server on the site Secure by design — proper capability checks, input sanitization, and per-post permission validation WPCS compliant — fully passes WordPress Coding Standards (phpcs) MCP-ready — all abilities include show_in_rest and mcp.public metadata Available Abilities Read (safe, query-only): Get posts with filters (status, category, tag, search) Get single post details (content, SEO meta, featured image) Get categories, tags, pages, comments, media, and users Write (create & modify): Create, update, and delete posts Create categories and tags Create pages Moderate comments Reply to comments as the authenticated user Upload images from external URLs to the media library (with optional auto-assign as featured image) Duplicate any post, page, or custom post type item — including all post meta (ACF, SEO, featured image) and taxonomy terms;
