Solve the Net

Phil Erb

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.

Disable XML-RPC


Dead simple as it should be. Nice, thank you for that.


Reduced to perfection

Disables the XML-RPC API in WordPress 3.5+, which is enabled by default.

DeveloperWil

Completely disables the XML-RPC API which was introduced in WordPress 3.5 and above which lets remote clients post, upload and edit content.
Notes: 
If you are using the WordPress smart phone app or the Jetpack plugin, please note that they need this service enabled.
If you activate this plugin your WordPress phone app will not be able to connect to your site and Jetpack will not be able to connect to wordpress.com where site visitor data (and other stuff) is stored.
Other plugins and services that use the XML-RPC API will also not function properly.
