A WordPress plugin that exposes your site as a Model Context Protocol server. AI agents — Claude.ai web, Claude Desktop, ChatGPT, custom clients — can read and write posts, pages, media, users, menus, WooCommerce orders, and Elementor pages, with every call going through capability gating, rate limiting, and an audit log. Distributed via the official WordPress.org plugin directory.

Quick facts

Capabilities

WordPress core (73 tools, always available)

• Content — Posts, pages, custom post types (full CRUD + revisions + featured images)
• Taxonomies — Categories, tags, custom taxonomies, term meta, post-term linking
• Media — Browse, upload (URL or base64), update metadata, delete
• Comments — Create, moderate (approve / spam / trash)
• Users — Read display names + roles (emails and usernames are not exposed)
• Menus — Read, create items, reorder, update with destructive-write guardrails
• Theme — Custom CSS, theme mods, active theme detection
• Site — Permalink structure, options (allowlisted), site info
• Search — Cross-content search by query
• SEO — Yoast / Rank Math / AIOSEO meta read/write where the plugin is active
• Diagnostics — Site status (WP/PHP/MySQL/plugins/themes/cron in one call), PHP error-log tail, WP cron schedule, and MCP royal_mcp_connection_health (returns route, auth method, session ID, plugin version, and active page-builder versions for Divi + Elementor + Gutenberg)

Plugin integrations (71 tools, conditional)

Auto-register only when the integrated plugin is active.

WordPress Abilities API bridge (WP 6.9+)

WordPress 6.9 shipped the Abilities API — a primitive that lets plugins register typed capabilities AI agents can call. As of 1.4.38, every Royal MCP tool also registers as a WordPress ability, giving you three ways to reach the same handlers:

1. Native — Royal MCP's /wp-json/royal-mcp/v1/mcp Streamable HTTP endpoint (unchanged, always available).
2. WP MCP Adapter — if the wordpress/mcp-adapter package is installed, Royal MCP registers a named royal-mcp-server on the mcp_adapter_init hook alongside adapter's default server.
3. WP core REST — direct ability invocation at /wp-json/wp-abilities/v1/abilities/{name}/run for callers that prefer the core WP endpoint.

Same handlers, three transports, one set of per-tool capability gates. Bridge can be disabled with the royal_mcp_abilities_registration_enabled option (default: on).

What we don't do

Explicit scope boundaries — the integration model is "narrow tools that work reliably," not "expose every API surface."

• No widget-level Elementor generation from scratch. Atomic widgets (Editor V4) pass through opaque; we never decode atomic schemas because Elementor itself may shift them.
• No Beaver Builder / Divi / Bricks page-builder JSON writes. Standard post content is readable and writable; page-builder-specific JSON storage is opaque unless covered by a dedicated tool.
• No theme builder template creation (Elementor or otherwise).
• No core file modifications — Royal MCP never writes to wp-content/themes, wp-includes, or wp-admin.
• No plugin installation or upgrades via MCP. Discovery yes; install/activate/deactivate no.
• No raw SQL. Queries go through WP_Query and $wpdb->prepare() only.

Royal MCP Pro (paid)

The Free plugin is fully featured for individual site owners. Royal MCP Pro extends it for agencies and multi-site operators:

• Divi Pro suite — page clone, image swap, template import, full library CRUD, D4→D5 Migrator, global preset bulk-apply (8 tools)
• Elementor Pro depth — additional Elementor tools beyond the Free integration
• Universal audit log — every AI operation logged with attribution + export
• 72-hour undo on every write — every destructive Pro tool returns an undo token; reverse any operation within the window
• License-gated updates through the standard WordPress updater — no runtime dependencies on external license servers

Connect

Install

1. Install from WordPress.org (recommended — auto-updates via WP admin) or upload the GitHub release zip.
2. Royal MCP → Settings → click Generate API Key.
3. Pick a client below.

Claude.ai web (OAuth — recommended)

Easiest path — no config file edits, no API key in your client.

1. In Claude.ai → Settings → Connectors → Add Custom Connector.
2. URL: https://yoursite.com/wp-json/royal-mcp/v1/mcp
3. Approve the OAuth consent screen when prompted. Claude.ai handles dynamic client registration + PKCE flow against your site.

Claude Desktop (.mcpb one-click bundle — new in 1.4.38)

Easiest Claude Desktop path — no mcp-remote, no npx, no config-file editing.

1. Download royal-mcp-1.4.38.mcpb from the latest GitHub release.
2. Double-click the .mcpb file — Claude Desktop opens the install prompt.
3. Enter your site URL + API key when prompted. Connection is live.

The bundle ships a zero-dependency stdio-to-HTTPS bridge in Node ≥18, which Claude Desktop already includes. See Claude Desktop MCP Bundles for the .mcpb spec.

Claude Desktop (OAuth via mcp-remote)

{

  "mcpServers": {

    "my-wordpress": {

      "command": "npx",

      "args": ["-y", "mcp-remote", "https://yoursite.com/wp-json/royal-mcp/v1/mcp"]

    }

  }

}

Config path: ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows).

Claude Desktop (API key)

Skip OAuth and authenticate via header:

{

  "mcpServers": {

    "my-wordpress": {

      "command": "npx",

      "args": [

        "-y", "mcp-remote",

        "https://yoursite.com/wp-json/royal-mcp/v1/mcp",

        "--header", "X-Royal-MCP-API-Key:YOUR_API_KEY"

      ]

    }

  }

}

ChatGPT

ChatGPT's custom MCP connector takes the same URL as Claude.ai web. Follow ChatGPT's connector flow and paste https://yoursite.com/wp-json/royal-mcp/v1/mcp.

Raw HTTP (custom clients)

# 1. Initialize a session. -i prints headers so you can grab Mcp-Session-Id.

curl -i -X POST https://yoursite.com/wp-json/royal-mcp/v1/mcp \

  -H "X-Royal-MCP-API-Key: YOUR_KEY" \

  -H "Content-Type: application/json" \

  -H "Accept: application/json, text/event-stream" \

  -d '{

    "jsonrpc": "2.0",

    "method": "initialize",

    "id": 1,

    "params": {

      "protocolVersion": "2025-11-25",

      "capabilities": {},

      "clientInfo": {"name": "my-app", "version": "1.0"}

    }

  }'



# 2. List available tools using the session id from the response header.

curl -X POST https://yoursite.com/wp-json/royal-mcp/v1/mcp \

  -H "X-Royal-MCP-API-Key: YOUR_KEY" \

  -H "Mcp-Session-Id: <session_id>" \

  -H "Content-Type: application/json" \

  -d '{"jsonrpc": "2.0", "method": "tools/list", "id": 2}'
