Claude.ai Remote MCP: Connect Without Config Files (OAuth Setup)

Posted
Byaiadmin

After this 5-minute setup, Claude.ai will be connected to your WordPress site — no config files, no JSON editing, no technical setup. Just click “Connect” and start chatting with your site.

Before You Start

You’ll need:

  • Understand what MCP is (MCP for Beginners)
  • AIWU plugin v4.9+ installed on your WordPress site
  • A Claude.ai account (Pro, Team, or Enterprise plan)
  • Your site must have HTTPS/SSL enabled
  • Time needed: ~5 minutes
💡 Why Remote MCP? Traditional MCP setups require editing JSON config files on your computer. Remote MCP with OAuth works like “Sign in with Google” — click once, authorize, done. It works on any device, in any browser.

Step 1: Enable Remote MCP in AIWU

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

Find the Remote MCP (OAuth 2.1) section. Toggle it ON. Click Save Settings.

What you should see: An OAuth Authorization URL appears — something like https://yoursite.com/wp-json/aiwu/mcp/oauth/authorize. You don’t need to copy this — Claude will discover it automatically.

Step 2: Connect from Claude.ai

Go to claude.ai. Click on your profile icon → Settings → Integrations (or look for the MCP / Tools section).

Click Add Integration or Connect MCP Server.

Enter your site’s MCP discovery URL:

https://yoursite.com/wp-json/aiwu/mcp/v1/discovery

Claude will auto-detect your AIWU server. Click Connect.

Step 3: Authorize the Connection

Claude redirects you to your WordPress site with an authorization screen. It looks similar to “Sign in with Google” — showing what permissions Claude will have.

Review the permissions, then click Authorize.

You’re redirected back to Claude.ai.

✅ Connected! Claude.ai now shows your WordPress site in its integrations panel.

Verify It Works

In a new Claude conversation, type:

“List the 5 most recent posts on my WordPress site”

What you should see: Claude calls your AIWU MCP server and returns a list of actual posts from your site — with titles, dates, and statuses.

Try a few more commands to test different capabilities:

  • “How many published posts do I have?”
  • “Show me unpublished drafts”
  • “What are my top WooCommerce categories?”

Managing Your OAuth Connection

Revoke access

In WordPress Admin → AI Copilot → MCP → OAuth Tokens — you can see all active connections and revoke any at any time. This immediately invalidates the token and disconnects Claude.

Token rotation

AIWU uses refresh tokens. Your connection stays active without needing to re-authorize, as long as you use it at least once every 30 days. If a token expires, you’ll be prompted to authorize again.

What permissions does Claude get?

The authorization screen shows exactly what Claude can access. By default, AIWU grants:

  • Read and write WordPress posts and pages
  • Read and write WooCommerce products and orders
  • Search the AIWU knowledge base
  • Trigger AIWU workflows

You can restrict permissions in MCP → Settings → Permission Scopes.

Common Issues

Problem: “Discovery URL not found” error in Claude.
Fix: Make sure Remote MCP is toggled ON in AIWU settings. Also verify your URL is correct: https://yoursite.com/wp-json/aiwu/mcp/v1/discovery — open this in a browser, you should see JSON (not an error page).

Problem: Authorization page shows a security warning or doesn’t load.
Fix: Your SSL certificate may have expired or is self-signed. Check SSL Labs for your domain. Claude.ai requires a valid SSL certificate for OAuth connections.

Problem: Cloudflare blocking the OAuth callback.
Fix: Some Cloudflare security rules block OAuth redirects. Go to Cloudflare → Security → WAF and add an exception rule for paths containing /wp-json/aiwu/mcp/. See the full guide: MCP Troubleshooting.

Problem: Connected but Claude says “no tools available”.
Fix: Go to AIWU → MCP → Settings and verify that the MCP tools are enabled. Try disconnecting and reconnecting from Claude.ai settings.

Still stuck? Check the MCP Troubleshooting Guide which covers Cloudflare, SSL, and connection issues in detail.
