ChatGPT + MCP: Connect ChatGPT to Your WordPress Site
ChatGPT supports MCP connections through OpenAI’s plugin framework and through third-party MCP bridges. This guide shows how to connect ChatGPT (desktop app and web) to your AIWU WordPress site, so you can use ChatGPT’s interface to work with live site data — just like Claude.
Before You Start
- AIWU Pro with MCP enabled and an API token generated (see MCP for Beginners)
- ChatGPT Plus or higher (required for plugin/tool access)
- Time needed: ~15 minutes
Option A: ChatGPT Desktop App with MCP (Recommended)
The ChatGPT desktop app (Mac and Windows) supports MCP server connections natively, similar to Claude Desktop.
- Download and install the ChatGPT desktop app from openai.com/chatgpt/download
- Open the app → click your profile → Settings
- Under Connected tools → MCP Servers → Add
- Enter your AIWU MCP URL:
https://yoursite.com/wp-json/aiwu/v1/mcp - Authentication: Header —
Authorization: Bearer YOUR_TOKEN - Click Connect
In a new ChatGPT conversation, type: “List my 5 most recent WordPress posts.” ChatGPT should return live data from your site.
Option B: ChatGPT Web via MCP Bridge
ChatGPT’s web interface doesn’t support direct MCP connections yet, but you can bridge it using a local MCP proxy tool.
Using mcp-proxy (open source):
- Install Node.js on your computer (nodejs.org)
- Run:
npx @anthropic/mcp-proxy(installs and starts automatically) - Configure the proxy with your AIWU MCP URL and token
- The proxy creates a local endpoint that ChatGPT’s Custom GPT can call
Option C: Custom GPT with AIWU API
An alternative to MCP: create a Custom GPT in ChatGPT that calls AIWU’s REST API directly.
- Go to chatgpt.com → Explore GPTs → Create a GPT
- In the GPT builder → Configure → Actions → Create new action
- Import schema from:
https://yoursite.com/wp-json/aiwu/v1/openapi.json - Set authentication: API Key → Header →
Authorization: Bearer YOUR_API_KEY - Add a system prompt: “You are an assistant with access to [site name]’s WordPress site. Use the available actions to read and manage content when asked.”
This creates a private Custom GPT that can read your posts, create drafts, and query WooCommerce data — accessible in ChatGPT’s web interface.
What ChatGPT Can Do via AIWU MCP
The same operations available to Claude apply to ChatGPT:
- Search and read posts, pages, products
- Create draft posts and pages
- Query WooCommerce orders and products
- Update post metadata and categories
- Trigger AIWU workflows

Claude vs. ChatGPT for MCP: Which Is Better?
| Factor | Claude Desktop | ChatGPT Desktop |
|---|---|---|
| MCP setup ease | ⭐⭐⭐⭐⭐ Native, simple config | ⭐⭐⭐⭐ Good but slightly newer |
| Long document handling | ⭐⭐⭐⭐⭐ Excellent context window | ⭐⭐⭐⭐ Good |
| Code generation | ⭐⭐⭐⭐ Excellent | ⭐⭐⭐⭐⭐ Slightly better for complex code |
| MCP spec compliance | ⭐⭐⭐⭐⭐ Best — Anthropic created MCP | ⭐⭐⭐⭐ Good, improving rapidly |
Both work well. Use whichever AI assistant you prefer — AIWU’s MCP server is compatible with both.
