If a plugin supports the Abilities API, your AI can use it out of the box. One-Click Connect with OAuth 2.0/2.1 Skip manual token copy-paste. Your WordPress MCP endpoint ships with a full OAuth 2.0/2.1 authorization server — PKCE, refresh-token rotation, and Dynamic Client Registration (RFC 7591) built in. Compatible MCP clients like Claude Desktop can connect with a single click: they register themselves, you approve the scopes on a consent screen, and you’re done. Bearer tokens still work for power users and automation. Built for Security Giving an AI access to your site is serious — so security is built into every layer: Bearer token authentication with SHA-256 hashing — the raw token is never stored Per-token permissions — create a read-only token for one AI, a full-access token for another WordPress capability checks on every single tool call Rate limiting per token (default 60 requests/min, configurable) Full audit trail — every tool call is logged in a searchable user activity log with the token used, arguments, result, and client IP IP whitelisting — optionally restrict which IPs can use the MCP endpoint Simple Admin Interface Dashboard — your MCP endpoint URL and one-click connection configs for every major AI client API Tokens — create and manage tokens with a checkbox-based tool permission tree Audit Log — a paginated, searchable user activity log of every AI action taken on your site Change History — a dedicated page with before/after snapshots of every MCP-originated write, inline diff expand, and user / object / date filtering Settings — tune rate limits, audit and change-history retention, IP whitelist, and more External services This plugin connects to the following third-party services only after a site administrator explicitly enables them in Easy MCP AI → External Data (by saving their own external account credentials). Nothing is contacted on a default install. Ahrefs Domain Rating API — api.ahrefs.com When: only after an administrator saves an Ahrefs APIv3 key and enables the tool under Easy MCP AI → External Data → Ahrefs (it is OFF by default — nothing is contacted on a default install). Thereafter: when an authorized MCP client calls the wp_ahrefs_domain_rating_free tool, and once each time an administrator saves the key or presses Test Connection on the External Data screen (both validate the key against Ahrefs). What is sent: your Ahrefs APIv3 key, as an Authorization: Bearer header, plus the target domain or URL supplied with the call. No WordPress credentials or personal data are transmitted. Terms: https://ahrefs.com/legal/domain-rating-license Privacy: https://ahrefs.com/legal/privacy-policy Semrush API — api.semrush.com, www.semrush.com When: only if an admin saves a Semrush API key. What is sent: the configured Semrush API key plus the parameters supplied per call (target domain, target URL, keyword/phrase, database/region code, display limits). Terms: https://www.semrush.com/company/legal/terms-of-service/ Privacy: https://www.semrush.com/company/legal/privacy-policy/ DataForSEO — api.dataforseo.com When: only if an admin saves a DataForSEO account login + API password. What is sent: the configured DataForSEO login + API password (HTTP Basic auth), plus the parameters supplied per call (keyword, target domain, target URL, location code, language code). Terms: https://dataforseo.com/terms-of-use Privacy: https://dataforseo.com/privacy-policy SE Ranking API — api.seranking.com When: only if an admin saves a SE Ranking API key. What is sent: the configured SE Ranking API key (sent as an Authorization token) plus the parameters supplied per call (target domain, target URL, keyword, region/source code, search engine, display limits). Terms: https://seranking.com/legal/terms-of-service.html Privacy: https://seranking.com/legal/privacy-statement.html Google Analytics 4 Data API & Google Search Console API — analyticsdata.googleapis.com, searchconsole.googleapis.com / www.googleapis.com/webmasters/v3 (token exchange via oauth2.googleapis.com) When: only if an admin uploads a Google service-account JSON. What is sent: a signed JWT minted from the service-account key, plus the chosen target and per-call parameters — for Analytics, the GA4 property id and report definition (dimensions, metrics, date range, filters); for Search Console, the site URL and query parameters (date range, dimensions, URL to inspect, sitemap URL). Terms: https://policies.google.com/terms Privacy: https://policies.google.com/privacy Easy MCP AI connection diagnostics (optional) — easymcpai.com When: only if you click the Diagnose Connection button on the Easy MCP AI dashboard. The plugin never contacts this service on its own — it simply opens the page in a new browser tab. What is sent: only your site’s address (its hostname), so the diagnostic page can check that your MCP endpoint is reachable. No credentials, content, or personal data are sent.

The most complete WordPress MCP server — 200+ tools, OAuth 2.0, WebMCP-ready, and nothing leaves your site. Royal MCP gives Claude, ChatGPT, Google Gemini, Perplexity, DeepSeek, Mistral, and every other MCP-compatible AI structured access to your WordPress site: 85 WordPress core tools plus 120 integration tools that auto-load for WooCommerce, Elementor, Divi, ACF, Yoast SEO, UpdraftPlus, WPForms, Solid Security, Contact Form 7, MonsterInsights, W3 Total Cache, Duplicator, BuddyPress, and more. Connect Claude to WordPress Royal MCP connects your WordPress site directly to Claude Code, Claude Desktop, or Claude.ai. Setup takes a minute or less: install the connector, authorize, and start your chat. Edit Elementor with Claude First-time setup walkthrough: royalplugins.com/support/royal-mcp/connecting-to-claude/ Plugins with dedicated MCP tools WooCommerce, Elementor, Divi, Advanced Custom Fields, Yoast SEO, UpdraftPlus, WPForms, Solid Security, Contact Form 7, MonsterInsights, W3 Total Cache, Duplicator, BuddyPress, Redirection — plus every Royal Plugin (Royal AI Firewall, GuardPress, SiteVault, ForgeCache, Royal Ledger, Royal Links). Not seeing yours? MCP still works. WordPress core operations (posts, pages, media, users, taxonomies, custom fields, menus, options) cover most day-to-day AI workflows for any plugin — read/write ACF via wp_get_post_meta even without ACF-specific tools, edit posts on any custom post type, moderate any plugin’s comments. Shared SEO meta tools automatically work with Rank Math, AIOSEO, SEOPress, and SEObolt. A dedicated integration layers specialized tools on top when that plugin exposes its own data model, request features/plugins support here on the wp.org support forum. Connect ChatGPT to WordPress ChatGPT on the web, desktop, and iOS supports MCP servers natively. Add Royal MCP in ChatGPT’s Plugins panel, authorize once, and ChatGPT can read your posts, publish drafts, update product prices, moderate comments, and audit SEO across your site — all through ordinary conversation. First-time setup walkthrough: royalplugins.com/support/royal-mcp/connecting-to-chatgpt/ Works with every MCP-compatible AI client Royal MCP is not vendor-locked. Claude/Anthropic, ChatGPT/OpenAI, Gemini/Google, Grok/xAI, Llama/Meta, Mistral, DeepSeek, Qwen/Alibaba, Cohere, and Perplexity all work through MCP-compatible clients like Cursor, Windsurf, Cline, Continue, Zed, JetBrains AI Assistant, OpenCode, Warp, Ollama, and LM Studio, all connecting through the same endpoint. Switch AI vendors without rewriting a single connection. Ready for browser-based AI agents (WebMCP) Royal MCP supports the W3C WebMCP browser-agent standard on the server side. When a visitor is signed into your site, browser-based AI agents from any WebMCP-compatible bridge (Cloudflare’s WebMCP is the first shipping today) can call the same MCP tools that Claude Desktop and ChatGPT already use, authenticated with the visitor’s existing WordPress login. Turn it on with one toggle in the Browser Agents section of the Royal MCP settings. External clients like Claude Desktop, ChatGPT, and Cursor continue to use OAuth Bearer tokens as before. How Royal MCP handles authorization Royal MCP speaks full OAuth 2.0 with PKCE and Dynamic Client Registration (RFC 7591) for Claude Desktop, Claude Code, ChatGPT web, and every modern MCP client. Sessions expire, refresh automatically, and can be revoked globally with one button in wp-admin. Clients that don’t speak OAuth get timing-safe API-key auth, per-IP rate limits (60 requests per minute), and the same activity log for every tool call. Where do my credentials go? Nowhere. Your AI client authenticates straight to your WordPress site, and every API key, OAuth token, session, and audit-log entry stays inside your own database. There’s no hosted server sitting between your chat and your site, and no license check or telemetry reaching out on activation. Ollama and LM Studio are first-class platforms alongside Claude, ChatGPT, and Gemini if you want to keep AI inference local too. Can I undo what the AI does? Yes. Every MCP client (Claude Desktop, ChatGPT, and the rest) asks you to approve or deny each destructive tool call by default, until you flip that setting in your connector. On top of that, Royal MCP captures a reverse-state snapshot before every destructive write and hands back a 72-hour undo token. One mcp_undo_last_operation call reverses the change — whether Claude deleted a post, replaced text on an Elementor page, updated a WooCommerce product, or reordered menu items. New posts and pages start as drafts, so nothing the AI writes appears on your live site until you approve publishing. Every tool call also lands in an activity log you can review from wp-admin. Does Royal MCP work with the WordPress Abilities API? Yes. Royal MCP surfaces every AI-callable operation through one endpoint, from three sources: the 85 native tools Royal MCP ships, the 120 integration tools that auto-load when WooCommerce, Elementor, Divi, ACF, Yoast SEO, UpdraftPlus, WPForms, Solid Security, Contact Form 7, MonsterInsights, W3 Total Cache, Duplicator, BuddyPress, and other supported plugins activate, and every ability any plugin registers through WordPress 6.9’s Abilities API. Your AI sees them all as MCP tools — one connector, no per-plugin setup, no per-vendor rewrite. See what AI agents do to your site The free Royal AI Firewall companion shows every AI agent hitting your site at the HTTP layer (training crawlers, retrieval bots, AI search engines), not just the ones connected through Royal MCP. Install both for a unified view across MCP tool calls and HTTP-layer bot hits. Discoverable by every AI agent scanner (Agent Readiness) Royal MCP publishes machine-readable MCP Server Card, Skills Index, and OAuth Protected Resource metadata at the standard well-known locations. Cloudflare’s Agent Readiness scanner, Vercel’s is-agentic, and Chrome Lighthouse’s Agentic Browsing audit all recognize your site as agent-ready with zero configuration. Every request to your MCP endpoint carries a Link header pointing agent runtimes at these discovery documents. 85 Core Tools + 120 Integration Tools WordPress Core (85 tools): Posts – create, read, update, delete, search, count (any registered public post type, featured images supported) Pages – full CRUD with parent page support Post Types – discover all registered public post types on the site Post Revisions – list revision history and roll a post back to any prior version Media – browse, upload from URL or base64, update alt text/caption/title/description, set as featured image, delete Comments – create, read, delete; full moderation suite (list pending, approve, mark spam, trash) Users – display names and roles (emails and usernames are not exposed) Categories, Tags & Custom Taxonomies – full CRUD, assign, count, discover registered taxonomies Term Meta – read/update/delete (most useful for term-level SEO fields on categories and tags) Menus – create menus, list, and full CRUD + reorder on menu items Publish and Promote – publish a draft and insert into a menu in one call Preview Links – generate a shareable draft-preview URL without a WP login Post Meta – read/update/delete custom fields (works with ACF, MetaBox, JetEngine, Pods, CPT UI) SEO Meta – read/write Yoast, Rank Math, AIOSEO, or SEObolt title/description/focus keyword/robots/OG (auto-detects active plugin) SEO Audit – fetch a post’s rendered HTML and report title, meta description, canonical, viewport, OG, Twitter Card Widgets – list, list sidebars, update content (writes gated by theme-appearance admin toggle) Find and Replace – literal replace with dry-run preview, expected-count safety, read-after-write verification Undo – reverse the previous delete or reorder within 72 hours via mcp_undo_last_operation Site Info + Site Status – name, WP/PHP versions, active theme + plugins, cron activity — for AI-driven pre-write validation Error Log + Cron Schedule – read recent PHP errors and scheduled WP cron events Connection Health – MCP session diagnostic (route, auth method, session ID, plugin version) Plugins & Themes – list installed with active status Theme Appearance – get theme, read/write theme mods (gated), read/write Custom CSS Search + Permalink Structure – full-text content search; read/write permalinks (gated) Options – read allowlisted core options, read plugin settings (sensitive keys redacted), write to allowlisted options when enabled Third-Party Plugin Integrations (auto-detected) If the plugin is active on your WordPress site, it’s tools auto-register with no additional configuration needed.
