Perform other actions registered through the WordPress Abilities API.

All requests are verified against the authenticated user's permissions, ensuring ChatGPT only performs authorized actions on your WordPress site.

How to Troubleshoot ChatGPT and WordPress Connection Issues

If ChatGPT cannot connect to your WordPress site through the miniOrange MCP Server plugin, the problem may involve your hosting firewall, cache settings, or agent permissions. Use the following solutions to identify and fix common connection issues.

1. ChatGPT Cannot Reach Your Site

What you may see: ChatGPT reports that it could not reach your site or that site registration failed. You may also see a 403 or 429 error, even though your site opens normally in a browser.

Why it happens: Your hosting provider's firewall or a security service such as Cloudflare or ModSecurity may block ChatGPT's connection to your site.

How to fix it: If you use Cloudflare, create a Web Application Firewall (WAF) rule that skips the relevant security checks for these paths.

/wp-json/mosmcp/*
/index.php?rest_route=/mosmcp/*
/.well-known/oauth-*

If your hosting provider manages another firewall, ask them to allow POST requests to these paths. Some hosts, including Xserver and Lolipop, also restrict access from overseas. Ask your host how to create a narrow exception for the MCP connection.

2. The Plugin Reports a Missing Token

What you may see: The plugin's debug log displays the error missing_token.

Why it happens: Your hosting server may remove the Authorization header before it reaches WordPress. The plugin then cannot receive the authentication token it needs.

How to fix it: Contact your hosting provider and ask them to allow the Authorization header to pass through to WordPress REST API endpoints under /wp-json/.

3. The Plugin Cannot Register an Agent

What you may see: You receive a "No agent registered" or "Failed to create agent" error, even though your agent appears to be enabled.

Why it happens: Your website, caching plugin, or hosting server may serve an outdated version of the plugin's status page.

How to fix it: Clear your website, plugin, and hosting caches. Then, exclude /wp-json/mosmcp/ from caching rules. For example, if you use LiteSpeed Cache, add this path under Do Not Cache URIs.

After clearing the cache, try connecting ChatGPT again.

4. ChatGPT Cannot See All Tools

What you may see: ChatGPT displays no tools or shows fewer tools than you expected after connecting to WordPress.

Why it happens: Your agent's assigned user role may not have permission to use the required WordPress abilities.

How to fix it: Open the miniOrange MCP Server plugin in your WordPress dashboard and go to Agents. Edit your agent, select the appropriate user role, and enable the abilities you want to allow. Save your changes and run the connection test again.

ChatGPT can access only the tools and actions that your agent's permissions allow.
