Royal MCP – Secure AI Connector for Claude, ChatGPT & any LLM via MCP

Description

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, 124 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, plus 4 tool-discovery and page-verification helpers.

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.

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.

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. Every credential (API key, OAuth token, session, audit-log entry) stays inside your own WordPress database with no hosted middleman, no license check, and no telemetry; Ollama and LM Studio work first-class alongside Claude, ChatGPT, and Gemini if you want fully-local AI inference too.

Is there a preview/dry-run before writes?

Yes. High-blast writes like site options and your permalink structure accept a dry-run flag, so the AI can preview the exact change before committing. The response reports the current value, the proposed value, the size delta in bytes, and whether the option is autoloaded; for permalink changes, it also lists which public post types are affected and shows current-URL vs proposed-URL samples so you can spot the blast radius before rewrite rules flush. Pair that with the 72-hour undo token on every destructive write and you get preview, approve, commit, undo: a full safety loop that lets fully-autonomous agents work on a live production site without wiping it out.

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. Royal MCP also 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 124 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.

Compatible Clients & Frameworks

Royal MCP works with any MCP-compliant client, IDE, or AI agent framework — no per-tool configuration required. Each entry below describes the specific integration path Royal MCP provides for that target, so customers can answer “will this work with the tool I already use?”:

• Desktop AI apps – Claude Desktop (native MCP connector via OAuth 2.0), ChatGPT Desktop, Gemini Advanced.
• AI code IDEs – Claude Code, VS Code (with MCP extension), Cursor, Windsurf, Continue, Cline, Zed, JetBrains AI Assistant.
• API testing tools – Postman, Bruno, Insomnia (use the API key in the X-Royal-MCP-API-Key header).
• Custom field plugins – Advanced Custom Fields (ACF) has dedicated acf_* tools that return values formatted per each field’s Return Format setting (the same way the ACF UI shows them). MetaBox, JetEngine, Pods, CPT UI, and Custom Field Suite are supported through the wp_get_post_meta / wp_update_post_meta tools, so AI agents can populate custom fields just like a human editor.
• Page builders – Elementor and Divi have dedicated tools for safe clone-and-customize workflows (Elementor: clone a page, find/replace text, swap images, get an outline, import templates; Divi: format detection, layout validation, page outline, library read, find/replace with builder-format awareness) – see the Tools list. Widget-level creation from scratch is intentionally out of scope. Beaver Builder, Bricks, Gutenberg, Spectra, and Stackable store standard post content that is readable and writable by AI; page-builder-specific JSON storage is opaque unless covered by a dedicated tool.
• Multilingual – WPML, Polylang, TranslatePress: translated posts appear as separate posts and can be read/written via the standard post tools.
• AI agent frameworks – Any MCP-compatible framework (LangChain, AutoGen, CrewAI, LlamaIndex, Haystack, etc.).

MCP Spec Compliance

Royal MCP implements the MCP Streamable HTTP transport across every published spec revision — 2024-11-05, 2025-06-18, 2025-11-25, and 2026-07-28 — negotiated on the initialize handshake so every client gets the wire behavior it expects:

• Single /mcp endpoint for all JSON-RPC communication
• POST for client messages, GET for server-sent events, DELETE for session termination
• Stateless per-request transport — sessions still supported for backwards compatibility but not required
• Cryptographically secure session IDs with transient-based storage when clients do use them
• Origin header validation to prevent DNS rebinding attacks
• Proper CORS handling for browser-based MCP clients
• W3C WebMCP browser-agent standard supported on the server side
• Machine-readable Agent Readiness signals published at the standard well-known paths
• RFC 8288 Link headers on every MCP response pointing agent runtimes at the discovery documents

External Services

Royal MCP makes no outbound calls of its own — no telemetry, no license check, no update ping. The MCP protocol is inbound: your AI client authenticates and calls your site, and any data the AI sees is sent under whatever terms you’ve agreed to with that AI provider.
