What Is XML-RPC?
XML-RPC is a communication feature built into WordPress that allows external applications to interact with your website.
It was created to allow tools and services to connect to WordPress remotely.
Examples of XML-RPC usage include:
- Publishing posts from external applications
- Managing WordPress remotely
- Connecting mobile apps
- Integrating third-party services
The XML-RPC endpoint is usually located at:
https://yourwebsite.com/xmlrpc.phpWhy Does XML-RPC Matter?
For websites that do not use XML-RPC, leaving it enabled provides an additional feature that may not be needed.
Because XML-RPC allows remote requests, attackers may attempt to use it for:
- Password guessing attacks
- Automated login attempts
- Server resource abuse
This does not mean XML-RPC automatically makes a website unsafe, but unused features increase the number of things that need to be monitored.
What Problems Can XML-RPC Cause?
If XML-RPC is enabled and not required, it may contribute to:
- Increased automated attack attempts
- Additional server requests
- Unnecessary exposure of a remote access feature
On websites with limited resources, large numbers of automated XML-RPC requests can also affect performance.
Should XML-RPC Always Be Disabled?
Not necessarily.
Disable XML-RPC if:
✅ Your website does not use remote publishing
✅ You do not use the WordPress mobile app
✅ No external services require XML-RPC
Keep XML-RPC enabled if you use:
- WordPress mobile apps
- Remote publishing tools
- Services that specifically require XML-RPC
How To Disable XML-RPC
There are several ways to disable XML-RPC.
Option 1: Security Plugin
Many WordPress security plugins include an option to disable XML-RPC.
Enable the setting that blocks XML-RPC requests if your website does not need it.
Option 2: Hosting or Server Settings
Some hosting providers allow XML-RPC access to be restricted through:
- Security settings
- Web application firewalls
- Server configuration
Option 3: Custom Code
Developers can disable XML-RPC through WordPress filters or server rules.
This should only be done carefully because incorrect changes can affect website functionality.
How Pixeljuice Checks XML-RPC
Pixeljuice checks whether the WordPress XML-RPC endpoint is accessible.
The check helps identify whether this remote communication feature is enabled and available.
If XML-RPC is not required, disabling it can reduce unnecessary exposure.
Summary
XML-RPC is a built-in WordPress communication feature that allows external services to connect with your website.
For websites that do not use it, disabling XML-RPC can reduce unnecessary exposure and simplify website security.
Before disabling it, confirm that your website does not rely on:
✅ WordPress mobile apps
✅ Remote publishing tools
✅ Third-party integrations
A feature that is not needed is usually better disabled.
