Royal MCP – Secure AI Connector for Claude, ChatGPT & Gemini

Royal MCP is a security-first Model Context Protocol (MCP) server for WordPress. It gives AI platforms like Claude, ChatGPT, and Google Gemini structured access to your WordPress content — with authentication, rate limiting, and audit logging that most MCP implementations skip entirely.

According to recent security research, 41% of public MCP servers have no authentication and respond to tool calls without any credentials. Royal MCP takes the opposite approach: every MCP session requires an API key, every request is rate-limited, and every interaction is logged.

Why Security Matters for MCP

MCP gives AI agents the ability to read, create, update, and delete your WordPress content. Without proper authentication, anyone who discovers your MCP endpoint can:

• Read all your posts, pages, and media
• Create or delete content
• Access user data and plugin information
• Overwhelm your server with rapid-fire requests

Royal MCP prevents all of this with API key authentication on session initialization, timing-safe key comparison, per-IP rate limiting (60 requests/minute), and a full activity log of every MCP interaction.

Plugin Integrations (Conditional)

Royal MCP automatically detects compatible plugins and adds specialized MCP tools. No configuration needed — if the plugin is active, the tools appear.

WooCommerce Integration (26 tools): When WooCommerce is active, AI agents can manage your store end-to-end:

• Browse and search products by category, status, or type
• Create and update simple and variable products with prices, SKUs, stock levels
• Manage variable products — list, get, create, update, delete, and batch-update product variations
• Manage global attributes (pa_* taxonomies) — list registered attributes, list attribute terms, register new attributes, assign attributes to a product as variation axes
• Manage coupons — list, search by code, get, create, update, delete (trash or permanent), and bulk-purge trash; supports all standard WC coupon fields (discount type, expiry, usage limits, product/category restrictions, email allowlists)
• View orders, order details, and update order status
• List customers with order count and total spent
• Get store statistics — revenue, order count, average order value by period

GuardPress Integration (7 tools): When GuardPress is active, AI agents can monitor your site security:

• Get current security score and grade with factor breakdown
• View security statistics — failed logins, blocked IPs, alerts
• Run vulnerability scans and review results
• List blocked IP addresses and failed login attempts
• Browse the security audit log filtered by severity

SiteVault Integration (6 tools): When SiteVault is active, AI agents can manage your backups:

• List available backups filtered by status or type
• Trigger new backups (full, database, files, plugins, themes)
• Check backup progress in real time
• View backup statistics — total size, last backup, counts
• List and review backup schedules

ForgeCache Integration (3 tools): When ForgeCache is active, AI agents can manage your page cache:

• Clear the entire cache, or purge a specific URL
• View cache statistics — hit rate, file count, total size

Royal Ledger Integration (4 tools): When Royal Ledger is active, AI agents can review your software costs and license data:

• List recurring software costs and renewal dates
• Get cost summaries grouped by month, vendor, or category
• List stored license keys (key VALUES are never exposed — only masked previews; decryption requires logging into wp-admin)

Royal Links Integration (3 tools): When Royal Links is active, AI agents can manage your branded short links:

• List existing links with click counts and target URLs
• Create new branded short links
• Get click statistics for any link

Royal MCP and the WordPress Core Abilities API

WordPress 6.9 shipped the Abilities API in November 2025 — a primitive that lets plugins register typed capabilities AI agents can call. Core ships three default abilities (site info, user info, environment info) and the wordpress/mcp-adapter package bridges abilities to the MCP protocol.

Royal MCP is a complete, production-ready MCP server that predates the official adapter. It runs the full Streamable HTTP transport, enforces API key authentication on every request, ships OAuth 2.0 for Claude Desktop’s native connector flow, rate-limits per-IP, redacts sensitive data, and logs every interaction. Out of the box it includes 67 tools for WordPress core operations plus 49 integration tools that auto-load when WooCommerce, GuardPress, SiteVault, ForgeCache, Royal Ledger, or Royal Links is active.

Supported AI Platforms

• Claude (Anthropic) — Full MCP support via Claude Desktop, Claude Code, and VS Code
• OpenAI / ChatGPT — GPT-4o, GPT-4 Turbo, GPT-3.5 Turbo
• Google Gemini — Gemini 1.5 Pro, 1.5 Flash
• Groq — Llama 3.3, Mixtral, Gemma 2
• Azure OpenAI — Azure-hosted OpenAI deployments
• AWS Bedrock — Claude, Llama, Titan models
• Ollama / LM Studio — Local self-hosted models (no external data transmission)

MCP Spec Compliance

Royal MCP implements the MCP 2025-11-25 Streamable HTTP transport specification:

• Single /mcp endpoint for all JSON-RPC communication
• POST for client messages, GET for server-sent events, DELETE for session termination
• Cryptographically secure session IDs with transient-based storage
• Origin header validation to prevent DNS rebinding attacks
• Proper CORS handling for browser-based MCP clients

External Services

This plugin connects to third-party AI services to enable AI platforms to interact with your WordPress content. No data is transmitted until you explicitly configure and enable a platform connection.

What data is sent: Your WordPress content (posts, pages, media metadata) as requested by the connected AI platform through authenticated MCP tool calls.

When data is sent: Only when you have configured a platform with API credentials AND enabled that platform connection AND the AI platform makes an authenticated request.
