ChatGPT MCP: Manage WordPress from ChatGPT Desktop

Posted
Byaiadmin

After this setup, you’ll be managing your WordPress site directly from ChatGPT Desktop — creating posts, checking orders, updating products — all through a conversation in ChatGPT.

In this article: Requirements · Setup Steps · Test Your Connection · Common Issues

Before You Start

You’ll need:

  • Understand what MCP is (MCP for Beginners)
  • AIWU plugin v4.9+ installed and activated
  • ChatGPT Desktop app for macOS or Windows (not the web version — MCP requires the desktop app)
  • ChatGPT Plus subscription (required for MCP in ChatGPT)
  • Your site must have HTTPS/SSL enabled
  • Time needed: ~15 minutes
⚠️ ChatGPT MCP requires the desktop app. This feature is not available in the ChatGPT web browser interface. Download the desktop app from openai.com if you haven’t already.
💡 Prefer Claude? If you use Claude.ai in a browser, the easier Remote MCP with OAuth requires no config files. This guide is for ChatGPT Desktop specifically.

Step 1: Get Your AIWU MCP Endpoint and Token

Go to WordPress Admin → AI Copilot → MCP → Settings.

You’ll see two values — copy both:

  • MCP Endpoint URL: https://yoursite.com/wp-json/aiwu/mcp/v1/sse
  • Access Token: aiwu_mcp_xxxxxxxxxxxxxxxxxxxxxxxx
WordPress Admin → AI Copilot → MCP → Settings — copy your Endpoint URL and Access Token from here.
⚠️ Keep your token private. This token gives full WordPress admin access via AI. Treat it like a password.

Step 2: Add AIWU to ChatGPT Desktop

Open the ChatGPT Desktop app. Go to Settings → Beta Features → Model Context Protocol. Make sure MCP is enabled.

ChatGPT Desktop → Settings → Beta Features — enable Model Context Protocol.

Locate the MCP config file

The config file location depends on your OS:

  • macOS: ~/Library/Application Support/ChatGPT/mcp.json
  • Windows: %APPDATA%ChatGPTmcp.json

Open this file in a text editor (create it if it doesn’t exist).

Add AIWU configuration

Add this JSON (replace the URL and token with your actual values):

{
  "mcpServers": {
    "aiwu-wordpress": {
      "type": "sse",
      "url": "https://yoursite.com/wp-json/aiwu/mcp/v1/sse?token=aiwu_mcp_xxxxxxxxxxxxxxxxxxxxxxxx"
    }
  }
}
The mcp.json file with AIWU configuration — paste this into your text editor and save.
💡 Multiple WordPress sites? Add each site as a separate entry with a unique key:
"aiwu-site1": { ... }, "aiwu-site2": { ... }

Restart ChatGPT Desktop

Completely quit and reopen the ChatGPT Desktop app. Config changes require a full restart.

Step 3: Test Your Connection

In ChatGPT Desktop, start a new conversation. Type:

“List all posts on my WordPress site”

What you should see: ChatGPT calls the AIWU MCP tool and returns a list of your actual WordPress posts.

Successful test — ChatGPT calls the AIWU MCP tool and returns your WordPress posts list.
✅ Working! If you see your WordPress posts listed, the connection is active. Try asking: “Create a draft post titled ‘Test MCP Connection'”

Things you can ask ChatGPT to do

  • “Create a draft post about [topic] with a 200-word introduction”
  • “List the last 10 WooCommerce orders and their totals”
  • “Search my knowledge base for information about [topic]”
  • “Show me all products that have no description”
  • “Update the title of post ID 123 to ‘[new title]'”

Common Issues

Problem: ChatGPT doesn’t show any MCP tools in the conversation.
Fix: Make sure you fully quit and relaunched the app (not just closed the window). Also verify the JSON in mcp.json is valid — a missing comma or bracket will break it. Use jsonlint.com to check.

Problem: “Connection refused” or timeout errors.
Fix: First, verify your site is accessible at the MCP URL: open https://yoursite.com/wp-json/aiwu/mcp/v1/sse?token=YOUR_TOKEN in a browser. You should see a streaming response (not an error). If you get a 403, check your Cloudflare settings — see MCP Troubleshooting.

Problem: “Unauthorized” error when ChatGPT tries to call a tool.
Fix: Double-check your token in the config file. Re-copy it from WordPress Admin → AI Copilot → MCP → Settings. Make sure there are no extra spaces or line breaks in the token value.

Problem: Config file doesn’t exist.
Fix: Create it manually. On macOS: open Terminal and run mkdir -p ~/Library/Application Support/ChatGPT && touch ~/Library/Application Support/ChatGPT/mcp.json. Then open it in a text editor and paste the JSON.
