How to Disable XML-RPC in WordPress
WordPress XML-RPC is a feature that allows external applications and services to communicate with a WordPress website remotely. It has been part of WordPress for many years and supports certain remote publishing, integration, and application-based workflows.
However, if your website does not require XML-RPC, disabling it can reduce an unnecessary attack surface. XML-RPC has historically been targeted by automated attacks, including large numbers of authentication requests and abuse of its remote procedure functionality.
In this guide, you’ll learn how to disable XML-RPC in WordPress, different methods for doing it, how to determine whether your website needs XML-RPC, and what to check if disabling it causes compatibility problems.
What Is XML-RPC in WordPress?
XML-RPC is a communication protocol that allows applications outside WordPress to interact with the website.
WordPress commonly exposes XML-RPC through:
https://example.com/xmlrpc.phpIt can allow remote applications to perform certain actions on a WordPress website without directly using the normal WordPress dashboard.
For example, XML-RPC has historically been used for:
- Remote publishing
- Mobile applications
- Third-party integrations
- External services
- Pingbacks
- Remote content management
Modern WordPress sites may use other APIs and integrations instead, so XML-RPC is not necessarily required for every website.
Why Disable XML-RPC in WordPress?
Disabling XML-RPC can be useful when your website does not depend on it.
1. Reduce the Attack Surface
Every enabled feature provides another component that needs to be maintained and protected.
If XML-RPC is not required, disabling it removes that particular interface from normal use.
2. Reduce Automated Abuse
XML-RPC has been used in automated attacks, including authentication attempts and other abusive requests.
Blocking unnecessary XML-RPC requests can reduce unwanted traffic.
3. Reduce Pingback Abuse
WordPress pingbacks can be abused to generate unwanted requests.
If your website does not use pingbacks or related XML-RPC functionality, disabling XML-RPC may be appropriate.
4. Simplify WordPress Security
A smaller attack surface can make security management easier.
However, disabling XML-RPC does not replace other WordPress security controls.
Should You Disable XML-RPC?
There is no universal answer.
You should first determine whether your website or an integration depends on it.
XML-RPC may still be required by:
- Certain mobile applications
- Remote publishing tools
- Older WordPress integrations
- Some third-party services
- Legacy plugins
If you disable it without checking dependencies, some features may stop working.
For a simple website that is managed entirely through the WordPress dashboard and does not use XML-RPC-dependent services, disabling it may be reasonable.
Check Whether XML-RPC Is Being Used
Before disabling XML-RPC, review your website’s plugins and integrations.
Look for:
- Mobile publishing tools
- External WordPress management services
- Remote publishing systems
- Older integrations
- Plugins that specifically mention XML-RPC
You can also review web server access logs for requests to:
/xmlrpc.phpA large number of requests does not necessarily mean that a legitimate service is using XML-RPC. It may simply indicate automated traffic.
Method 1: Disable XML-RPC Using a WordPress Security Plugin
For many administrators, using a reputable security plugin is the simplest method.
The exact option name varies by plugin.
You may find settings such as:
- Disable XML-RPC
- Block XML-RPC
- Disable XML-RPC authentication
- XML-RPC protection
Step 1: Create a Backup
Before modifying security or access settings, create a current backup of your WordPress files and database.
Step 2: Install a Trusted Security Plugin
Use a reputable security plugin from a trusted source.
Avoid downloading modified or unofficial copies.
Step 3: Find XML-RPC Settings
Open the plugin’s security settings and look for its XML-RPC controls.
Step 4: Disable XML-RPC
Enable the option to disable or block XML-RPC if you have confirmed that your website does not need it.
Step 5: Save the Settings
Apply the configuration.
Step 6: Test the Website
Check:
- WordPress login
- Dashboard
- Publishing
- Contact forms
- Membership functionality
- WooCommerce if installed
- External integrations
Make sure your normal website functionality continues to work.
Method 2: Disable XML-RPC With a WordPress Filter
If you prefer a lightweight approach, WordPress provides a filter that can disable XML-RPC functionality.
Add the following code to an appropriate site-specific code location:
add_filter( 'xmlrpc_enabled', '__return_false' );This tells WordPress to disable XML-RPC functionality.
Important Consideration
Do not edit WordPress core files to add this code.
Core files can be overwritten during WordPress updates.
Instead, place custom functionality in an appropriate location, such as a site-specific plugin or another properly managed customization mechanism.
Method 3: Block xmlrpc.php at the Web Server Level
Another approach is to block access to the XML-RPC endpoint before the request reaches WordPress.
The exact configuration depends on your web server.
For Apache environments, a rule can be configured to deny access to:
/xmlrpc.phpThe exact syntax and location depend on your hosting configuration.
Before modifying .htaccess or server configuration, create a backup and make sure you understand the impact of the rule.
An incorrect server rule can cause unexpected access problems.
Method 4: Block XML-RPC Using a Web Application Firewall
A Web Application Firewall can also be used to restrict requests to the XML-RPC endpoint.
This approach can be useful if you want to control traffic before it reaches your WordPress installation.
Depending on the WAF, you may be able to:
- Block all XML-RPC requests
- Rate-limit XML-RPC traffic
- Allow trusted sources
- Log requests
- Apply custom rules
A WAF can be especially useful when your website receives large amounts of unwanted automated traffic.
Method 5: Disable XML-RPC Through Hosting Security Tools
Some managed WordPress hosting platforms and security systems provide a setting to disable XML-RPC.
If your hosting provider offers this option, it may be preferable to use the hosting-level control rather than manually editing server configuration.
Check your hosting control panel or ask your hosting provider whether XML-RPC management is supported.
Disabling XML-RPC vs Blocking XML-RPC
These approaches are related but not always identical.
Disable XML-RPC
WordPress prevents XML-RPC functionality from operating normally.
Block the Endpoint
The server or firewall prevents requests from reaching xmlrpc.php.
Protect XML-RPC
The endpoint remains available but is restricted using controls such as rate limiting or access rules.
The best approach depends on whether your website actually requires XML-RPC.
What Happens After XML-RPC Is Disabled?
If your website does not depend on XML-RPC, you may notice no visible difference.
Normal visitors should still be able to:
- Browse pages
- Submit forms
- Read posts
- Purchase products
- Log in through standard WordPress authentication
However, services that depend on XML-RPC may stop working.
That is why testing is important after making the change.
How to Check Whether XML-RPC Is Disabled
After applying your chosen method, you should verify the result.
One simple test is to check:
https://example.com/xmlrpc.phpThe exact response depends on how XML-RPC has been disabled or blocked.
You can also review your server or firewall logs to determine whether requests are being blocked.
A security scanner or WordPress security plugin may also report the XML-RPC status.
XML-RPC and Brute-Force Attacks
One reason XML-RPC receives security attention is its ability to support certain remote authentication operations.
Attackers may attempt to abuse this functionality with automated requests.
Traditional login protection may not always address XML-RPC traffic in the same way as requests to the normal WordPress login endpoint.
If XML-RPC is required, consider protecting it with:
- Rate limiting
- WAF rules
- Monitoring
- Strong passwords
- Two-factor authentication where compatible
- Restricting unnecessary access
If XML-RPC is not needed, disabling it removes the endpoint from normal use.
XML-RPC and Pingbacks
Pingbacks are one of the features associated with XML-RPC.
A pingback allows websites to notify each other when one site links to another.
While this can be useful in some publishing workflows, pingback functionality has also been abused for unwanted traffic generation.
If your website does not use pingbacks, disabling XML-RPC or separately restricting pingback functionality may be appropriate.
XML-RPC vs REST API
It is important not to confuse XML-RPC with the WordPress REST API.
WordPress provides both interfaces for different purposes.
The REST API is commonly used by:
- Modern applications
- WordPress editor functionality
- Headless WordPress implementations
- JavaScript applications
- Third-party integrations
Disabling XML-RPC does not automatically disable the REST API.
Likewise, disabling the REST API is not required simply because you disabled XML-RPC.
Do not block APIs without understanding which features depend on them.
How to Disable XML-RPC Without Breaking Your Website
Follow this process:
Step 1: Identify Dependencies
Find out whether your plugins, applications, or integrations use XML-RPC.
Step 2: Back Up the Website
Create a reliable backup of the files and database.
Step 3: Choose the Least Complicated Method
For many websites, a trusted security plugin or appropriate site-specific configuration is easier to maintain than manually modifying server files.
Step 4: Disable XML-RPC
Apply your chosen configuration.
Step 5: Test Core Functionality
Check the dashboard, publishing, forms, ecommerce, membership, and integrations.
Step 6: Monitor Logs
Look for unexpected errors or blocked requests.
Step 7: Keep the Configuration Documented
Record what you changed and why.
This makes future troubleshooting easier.
Common Problems After Disabling XML-RPC
Problem 1: A Mobile App Stops Working
If the app depends on XML-RPC, disabling it may prevent remote access.
Solution
Determine whether the application supports another authentication or API method.
If XML-RPC is essential, consider protecting it rather than completely blocking it.
Problem 2: A Third-Party Integration Stops Publishing
Some older publishing systems may depend on XML-RPC.
Solution
Check the integration documentation and determine whether it supports the WordPress REST API or another modern integration method.
Problem 3: A Plugin Reports an XML-RPC Error
A plugin may display an error because it expects XML-RPC to be available.
Solution
Check whether the plugin actually requires XML-RPC.
If the feature is not essential, you may be able to leave XML-RPC disabled.
Problem 4: .htaccess Changes Break the Website
Incorrect rewrite or access rules can cause server errors.
Solution
Restore the previous configuration from your backup and review the rule with your hosting provider or server administrator.
How to Re-Enable XML-RPC
If you discover that an important service requires XML-RPC, you can reverse the change.
The exact process depends on how it was disabled.
For example, if you added:
add_filter( 'xmlrpc_enabled', '__return_false' );remove that customization from the appropriate site-specific code location.
If you used a plugin, disable the XML-RPC blocking option.
If you used a firewall or server rule, remove or adjust the corresponding rule.
After re-enabling XML-RPC, test the integration that requires it.
Should XML-RPC Be Completely Disabled or Protected?
Consider the following factors:
| Situation | Possible Approach |
|---|---|
| Simple website with no XML-RPC dependencies | Disable XML-RPC |
| Website using an XML-RPC-dependent service | Keep it enabled and protect it |
| High XML-RPC abuse | Use rate limiting/WAF or disable if unnecessary |
| Legacy integration | Verify compatibility before disabling |
| Managed hosting with XML-RPC controls | Consider using the hosting-level option |
There is no single configuration that fits every WordPress installation.
Additional WordPress Security Measures
Disabling XML-RPC should be part of a broader security strategy.
Keep WordPress Updated
Install WordPress security updates and maintain current plugin and theme versions.
Remove Unused Plugins
Delete plugins that are no longer required.
Use Strong Passwords
Every administrator should have a unique password.
Enable Two-Factor Authentication
2FA adds an additional layer to administrator authentication.
Protect the Login Page
Use rate limiting and other appropriate controls against automated login attempts.
Use a Web Application Firewall
A WAF can help filter malicious web traffic.
Monitor Administrator Accounts
Regularly review users and remove unauthorized accounts.
Maintain Backups
Keep independent backups and periodically test restoration.
Scan for Malware
Regular malware scanning can help identify unexpected changes.
Common Mistakes When Disabling XML-RPC
1. Disabling It Without Checking Dependencies
This can break legitimate services.
2. Editing WordPress Core Files
Core modifications can be overwritten during updates.
Use appropriate customization mechanisms instead.
3. Copying Random .htaccess Rules
Server configurations vary.
A rule that works on one server may cause problems on another.
4. Assuming XML-RPC Is the Only Security Risk
WordPress security involves many components.
Attackers can target plugins, themes, accounts, hosting, APIs, and other services.
5. Ignoring Logs
Logs can help determine whether XML-RPC is actually being targeted or used.
6. Forgetting to Test Integrations
A website may appear normal while a background integration has stopped functioning.

Frequently Asked Questions
What is the WordPress XML-RPC URL?
The standard XML-RPC endpoint is:
https://example.com/xmlrpc.phpIs XML-RPC still needed in WordPress?
Some websites and integrations may still require it, while others can operate without it. Check your website’s dependencies before disabling the feature.
Does disabling XML-RPC improve WordPress security?
It can reduce the attack surface and prevent abuse of the XML-RPC endpoint when that functionality is unnecessary. However, it does not secure the rest of the website by itself.
Can I disable XML-RPC without a plugin?
Yes. You can use WordPress configuration/code or server-level controls, depending on your hosting environment.
Does disabling XML-RPC disable the WordPress REST API?
No. XML-RPC and the REST API are separate interfaces.
Can disabling XML-RPC break WordPress?
It generally should not affect ordinary website browsing or dashboard administration, but services that depend on XML-RPC may stop working.
Should I disable XML-RPC on every WordPress website?
Not necessarily. First determine whether your website or any integration depends on it.
Final Thoughts
Disabling XML-RPC can be a useful security hardening step when your WordPress website does not need remote XML-RPC functionality. It can reduce exposure to unwanted XML-RPC traffic and eliminate one interface that attackers may attempt to abuse.
However, disabling XML-RPC is not a complete WordPress security solution. Combine it with strong passwords, two-factor authentication, login protection, regular updates, secure hosting, malware scanning, WAF protection, monitoring, and reliable backups.
Before blocking XML-RPC, always check whether your website depends on it. If an important service requires XML-RPC, protecting the endpoint with appropriate rate limiting and firewall controls may be more suitable than completely disabling it.
The best WordPress security configuration is one that removes unnecessary functionality while preserving the features your website genuinely needs.
