Pretty simply, this plugin uses the built-in WordPress filter “xmlrpc_enabled” to disable the XML-RPC API on a WordPress site running 3.5 or above.
Beginning in 3.5, XML-RPC is enabled by default. Additionally, the option to disable/enable XML-RPC was removed. For various reasons, site owners may wish to disable this functionality. This plugin provides an easy way to do so.
- Upload the disable-xml-rpc directory to the
/wp-content/plugins/directory in your WordPress installation
- Activate the plugin through the ‘Plugins’ menu in WordPress
- The WordPress XML-RPC methods are now disabled!
To re-enable XML-RPC, just deactivate the plugin through the ‘Plugins’ menu.

Is there an admin interface for this plugin?
No. This plugin is as simple as XML-RPC is off (plugin activated) or XML-RPC is on (plugin is deactivated).
How do I know if the plugin is working?
There are a few easy methods for checking if XML-RPC is off:
- Try using an XML-RPC WordPress client, like the official WordPress mobile apps. The WordPress mobile app should tell you that “XML-RPC services are disabled on this site” if the plugin is activated.
- Use the curl command to send an XML-RPC request to your site. If the response contains “XML-RPC services are disabled on this site” then the plugin is working properly and WordPress will not send data back to XML-RPC requests.
- Try the XML-RPC Validator, written by Danilo Ercoli of the Automattic Mobile Team – the tool is available at https://xmlrpc-check.hostpress.me/. Information and source code for the tool are available on GitHub at https://github.com/daniloercoli/WordPress-XML-RPC-Validator. Keep in mind that you want the validator to fail and tell you that XML-RPC services are disabled.
See the screenshots for examples of what these tools will return when the plugin is enabled.
Something doesn’t seem to be working correctly
If the plugin is activated, but XML-RPC appears to still be working … OR … the plugin is deactivated, but XML-RPC is not working, then it’s possible that another plugin or theme function is affecting the xmlrpc_enabled filter. Additionally, server configurations could be blocking XML-RPC (i.e. blocking access to xmlrpc.php in the .htaccess file).
