StifLi Flex MCP Documentation

Released in December 2025, StifLi Flex MCP was the first MCP plugin for WordPress and remains the most complete WordPress MCP platform for ChatGPT, Claude Desktop, and other MCP clients.

📡 MCP Server — Connect ChatGPT, Claude Desktop, and Other MCP Clients

StifLi Flex MCP includes a full standards-compliant MCP server for WordPress, so ChatGPT, Claude Desktop, LibreChat, and other MCP clients can connect directly to your site and use real WordPress tools through OAuth 2.1.

ChatGPT — Connect through Apps & Connectors with OAuth 2.1 authentication
Claude Desktop — Connect through Connectors with automatic OAuth flow
LibreChat and other MCP clients — Use the same MCP endpoint and discovery flow
Zero shared secrets — No custom API keys or passwords for external MCP clients
Standards-based — Automatic discovery, registration, and authentication with OAuth 2.1, PKCE, RFC 9728, RFC 8414, and RFC 7591

Just copy the SSE URL from the Settings page, paste it into ChatGPT, Claude Desktop, or another MCP client, and authorize.

✍️ AI Copilot — Your Writing Assistant Inside the Editor

The AI Copilot lives as a floating widget right inside the WordPress post and page editor. It understands the full context of what you’re editing — title, content, categories, tags, featured image, and even WooCommerce product fields — and helps you write better, faster.

Rewrite, expand, or optimize content — Ask the Copilot to improve your text and it applies the changes directly into the editor
One-click quick actions — “⚡ Optimize content”, “🏷️ Generate tags”, “📝 Write excerpt”, “🖼️ Generate image” — one tap, instant results
Real-time editing — The Copilot sets titles, excerpts, tags, slugs, and categories directly in the editor. No copy-pasting
Content block operations — Insert, update, replace, or delete Gutenberg blocks through conversation
Visual feedback — Changed fields and blocks are highlighted with a green border so you always see what the AI modified
Keep or Undo — Every change shows a floating banner: keep it or undo with a single click. You stay in control
Image generation — Ask the Copilot to generate an image and it sets it as the featured image or inserts it as a block, automatically
Works with Gutenberg and Classic Editor — Full support for both editors
Context-aware — The Copilot reads your current post content, blocks, metadata, and editor state to give relevant suggestions
WooCommerce-aware — When editing a product, the Copilot sees prices, stock, SKU, attributes, and product type

Choose OpenAI (GPT-5.4), Anthropic (Claude 4.6 Opus/Sonnet), or Google (Gemini 3.1 Pro/Flash), and optionally use WordPress AI Client connectors like OpenRouter and Mistral when installed. No complex setup — just your API key or connector credentials.

💡 What Can You Do With the Copilot?

Here are just a few examples of what you can ask while editing a post or page:

✏️ “Rewrite the introduction to sound more professional and engaging”
📊 “Add a comparison table below the second paragraph with pros and cons”
🖼️ “Generate an image that illustrates the idea in paragraph four and insert it right above”
📝 “Write a compelling meta description and set it as the excerpt”
🛒 “Update the product short description to highlight free shipping and set the sale price to $19.99”

The Copilot reads your full content, understands context, and applies changes directly in the editor — no copy-pasting, no switching tabs.

🤖 AI Chat Agent — Your WordPress AI Assistant

The built-in AI Chat Agent gives you a powerful conversational interface to manage your entire WordPress site:

Talk to your site — “Show me the last 5 orders”, “Create a blog post about SEO tips”, “What plugins are installed?”
Multi-provider — Built-in OpenAI (GPT-5.4, GPT-5.3), Anthropic (Claude 4.6 Opus/Sonnet, Claude 4.5 Haiku), Google (Gemini 3.1 Pro, Gemini 3 Flash) + optional WordPress AI Client connectors (OpenRouter, Mistral)
122+ MCP tools at its disposal — The AI agent can read posts, create content, manage WooCommerce products, check orders, inspect SEO data, update settings, and much more
Smart suggestions — After each response, get contextual follow-up suggestions
Conversation history — Auto-saved across sessions with multi-tab support
Safe by design — Choose “Always Allow” or “Ask User” mode for tool execution confirmations
Advanced tuning — Control temperature, max tokens, top_p, system prompts

💡 What Can You Do With It?

Here are just a few examples of what you can ask your AI agent:

📝 “Write a 500-word blog post about healthy eating and publish it as draft”
🛒 “Show me today’s WooCommerce orders and their total revenue”
🔍 “What are the top 10 most commented posts on my site?”
📊 “List all products with stock below 5 units”
🎨 “Generate a hero image for my latest blog post about technology”

The AI agent understands context, chains multiple operations, and works with your site’s real data in real time.

🎨 AI Image & Video Generation

Generate stunning images and videos directly from your AI agent or the dedicated Multimedia Settings page:

Image Generation — “Generate a hero image for my blog post about AI” using OpenAI (GPT Image family + DALL·E 2/3) or Google Gemini (Gemini Image + Imagen 4)
Image Search — “Find a real stock image for my post” with wp_search_image (Unsplash, Pexels, Pixabay) including attribution metadata
Video Generation — “Create a 5-second product showcase video” using OpenAI Sora or Google Veo 2/3

🧩 Code Snippet Management — Design and Develop Through Conversation

Create, edit, activate, and manage code snippets on your WordPress site entirely through AI — no manual coding required. Compatible with the three most popular snippet plugins: WPCode, Code Snippets, and Woody Code Snippets.

Add functionality instantly — “Add a PHP snippet that redirects users after login based on their role”
Custom CSS on demand — “Create a CSS snippet that hides the sidebar on mobile devices”
JavaScript injection — “Add a JS snippet that shows a sticky banner with a 10% discount code”
Full lifecycle management — List, create, edit, activate, deactivate, and delete snippets from conversation
Safe by design — PHP code is sanitized automatically, removing stray <?php tags and markdown artifacts from AI-generated output

This opens up powerful possibilities: customize your theme’s appearance, add tracking scripts, inject schema markup for SEO, modify WooCommerce checkout behavior, add custom shortcodes — all through natural language. Ask your AI agent to build it, test it, and activate it, without ever touching a code editor.

🧠 WordPress Abilities Integration (WordPress 6.9+)

Automatically discover and import abilities registered by other plugins into your AI agent’s toolkit. If a plugin supports the WordPress Abilities API, StifLi Flex MCP can detect, import, and expose it as an AI tool — zero configuration needed.

Scheduled Tasks — Create daily, weekly, or monthly automated workflows

⏪ Roll Back — The Only MCP Server With Undo

Mistakes happen. You asked ChatGPT to update your landing page and the result isn’t what you expected? No problem — roll back the change with one click and your site is restored instantly.

StifLi Flex MCP is the only MCP server for WordPress that tracks every change and lets you undo it. Every modification made by any AI — whether from ChatGPT, Claude Desktop, the built-in Chat Agent, the Copilot, or automated tasks — is recorded with a full before/after snapshot.

One-click Undo — Roll back any change from the Logs & Roll Back page in your admin panel
Redo support — Changed your mind? Re-apply a rolled-back change just as easily
Session rollback — Undo an entire AI conversation’s changes at once, in the correct order
Full audit trail — See exactly what was changed, when, by whom, and from which source
Works across everything — Posts, pages, products, orders, options, menus, media, code snippets, and more
AI-accessible — Your AI agent can also query and rollback changes through dedicated tools

💡 Real-world examples:

🛒 “ChatGPT updated all my product prices but used the wrong currency — roll it back!”
📝 “Claude rewrote my About page and I prefer the original — undo!”
⚙️ “An automation changed my site settings at 3 AM — I can see exactly what happened and revert it”
🎨 “The AI-generated image doesn’t match my brand — remove it and restore the previous one”
🔗 “I told the AI to delete a menu item by mistake — bring it back!”

External Services

This plugin connects to third-party AI services to power the AI Chat Agent, AI Copilot, image generation, and video generation features. No data is transmitted until you explicitly configure an API key and initiate a request.

What data is sent: Your WordPress content (post text, metadata, product details) as included in AI prompts, and MCP tool execution results when using the MCP server with external AI clients.

When data is sent: Only when you have configured an API key for a provider AND actively send a message to the AI agent or Copilot, or when an external MCP client makes an authenticated request to the MCP server endpoint.

Supported services and their policies:

OpenAI — Used for GPT models (AI Chat Agent, AI Copilot), GPT Image / DALL·E (image generation), and Sora (video generation)
Terms of Use | Privacy Policy
Anthropic Claude — Used for Claude AI models (AI Chat Agent, AI Copilot)
Terms of Service | Privacy Policy
Google Gemini — Used for Gemini AI models (AI Chat Agent, AI Copilot), Gemini Image + Imagen 4 (image generation), and Veo 2/3 (video generation)
Terms of Service | Privacy Policy
Google Search Console – Used only when you connect your Google account in the SEO settings, for read-only site/search performance data.
Terms of Service | Privacy Policy

When using the MCP server with external AI clients (ChatGPT, Claude Desktop, LibreChat, etc.), API requests are made by the AI client’s backend servers to your WordPress MCP endpoint. The plugin itself does not send data to third parties in this scenario — the external MCP client initiates all communication.
