Core Web Vitals and INP: Why Your WordPress Site May Be Losing Rankings in 2026

Artificial intelligence is becoming part of the way websites are built, managed and used.

WordPress is responding to this change by adding standard infrastructure that allows developers to connect WordPress with AI services and build AI assisted features.

Two important AI related additions arrived with WordPress 7.0: the AI Client and the Connectors API. WordPress 6.9 also introduced the Abilities API, while the official WordPress AI project includes an MCP Adapter that can connect WordPress abilities with AI applications.

For developers, these are important changes.

For business owners, the question is simpler:

What does this actually mean for my WordPress website?

The short answer

These updates do not automatically turn your WordPress website into an AI powered website.

Instead, WordPress is providing developers with standard tools for building AI functionality and connecting WordPress with AI services.

That could eventually support features such as AI assisted content management, intelligent search, automated workflows, website diagnostics and other tools.

Whether your website can use these features depends on the plugins, integrations or custom development installed on the website.

So there is no need to install an AI plugin simply because WordPress now has these capabilities.

The better approach is to understand what has changed and consider where AI could provide a genuine benefit to your business.

What has WordPress introduced?

There are four terms worth knowing:

• AI Client
• Connectors API
• Abilities API
• MCP Adapter

They are related, but they do different jobs.

The Abilities API was introduced in WordPress 6.9. The AI Client and Connectors API are part of WordPress 7.0. The MCP Adapter is an official package from the WordPress AI Building Blocks project rather than a standard Core feature bundled into WordPress itself.

Understanding that distinction is important.

1. WordPress AI Client

The AI Client is one of the most significant additions in WordPress 7.0.

It provides a standard PHP interface that plugins can use to communicate with AI models.

Previously, a plugin developer wanting to add AI functionality might build a direct integration with a particular provider.

The WordPress AI Client provides an abstraction layer instead.

A plugin can use the WordPress AI Client without having to build its entire AI connection around one specific provider. WordPress can route requests to a suitable model from a provider configured on the website.

WordPress Core does not include the AI providers themselves.

The official provider plugins currently include integrations for:

• OpenAI
• Google
• Anthropic

Other providers can also be developed and added.

Why does this matter to website owners?

You may not see the AI Client in your WordPress dashboard.

Its main benefit is for developers building WordPress functionality.

For example, a developer could create a plugin that uses the AI Client for:

• generating or summarising content
• analysing information
• processing text
• generating images
• creating AI assisted administrative tools
• building other AI based website features

The important point is that the AI Client provides the underlying connection. It does not automatically add these features to your website.

2. The Connectors API

AI services need a way to connect with WordPress.

The Connectors API, introduced in WordPress 7.0, provides a standard framework for registering and managing connections to external services.

Its initial focus is AI providers.

WordPress 7.0 includes a new Settings > Connectors area for configuring supported connections. The initial featured AI providers are Anthropic, Google and OpenAI.

This can make AI integrations easier for plugin developers because they do not all need to create their own separate system for handling provider connections.

For a website owner, this could eventually mean a more consistent way of managing AI services used by different WordPress features.

Does WordPress automatically send your website content to AI?

No.

Installing or updating WordPress does not by itself mean that your website content is automatically being sent to an AI provider.

The AI Client only makes an AI request when code uses it, and an AI provider needs to be configured for the request to be handled.

This distinction is important for website owners who may be concerned about privacy and data.

You should still check the privacy and data handling policies of any AI plugin or service you choose to install.

3. The Abilities API

The Abilities API arrived in WordPress 6.9.

This is different from the AI Client.

The Abilities API provides a standard way for WordPress, plugins and themes to register specific pieces of functionality.

An ability can have:

• a unique name
• a description
• defined inputs
• defined outputs
• permission rules
• a function that performs the action

This makes that functionality easier for other systems to discover and use.

For example, a plugin could register an ability that retrieves specific website information.

Another could register an ability that performs a particular content related task.

The important part is that the function is described in a standard, machine readable way.

Why is this useful for AI?

AI systems need to know what they are allowed to do.

The Abilities API provides a structured way of describing available functionality and the permissions required to use it.

This makes it useful for AI agents and automation systems, but the API is not limited to AI.

It can also be used by WordPress plugins, JavaScript, REST API applications and other systems.

4. What is the MCP Adapter?

This is where things become particularly interesting.

MCP stands for Model Context Protocol.

It provides a standard way for AI applications to communicate with external tools and sources of information.

The WordPress MCP Adapter is an official package in the AI Building Blocks for WordPress project.

Its role is to connect WordPress Abilities with MCP so that compatible AI applications can discover and use selected WordPress functionality.

For example, an AI application could potentially connect to a WordPress website and use an approved ability to retrieve specific information.

The key word here is approved.

The MCP Adapter does not simply give an AI unrestricted control over a WordPress website.

Abilities have permission controls, and the MCP Adapter requires abilities to be deliberately exposed for MCP access or included in a configured MCP server.

That makes security and permissions an important part of any real world implementation.

What could this mean for a business website?

For most website owners, these APIs are not something you need to configure yourself today.

Their importance is what developers can build with them.

Here are some possible applications.

AI assisted content management

A WordPress plugin could use the AI Client to help a website administrator summarise, organise or process content.

For example, an internal tool could help a marketing team review a large collection of articles.

Human review would still be important, particularly for business claims, technical information and customer facing content.

Better internal search

AI can be used to understand the meaning behind a search rather than relying only on exact words.

This could be useful for websites containing large amounts of information, such as:

• product catalogues
• documentation
• knowledge bases
• service information
• large blog archives

The WordPress AI infrastructure provides developers with another way to build such functionality.

It does not mean that every WordPress search box will automatically become an AI search engine.

AI assisted website administration

Developers can create tools that help administrators perform particular tasks.

For example, an internal tool could use AI to analyse selected website information and present the results to an administrator.

The Abilities API can provide structured functions that such tools can discover and use, subject to the permissions defined by the developer.

AI agents working with WordPress

The combination of the Abilities API and MCP Adapter creates another possibility.

An AI application could connect to selected WordPress abilities and use them as tools.

WordPress's own documentation demonstrates this with AI applications including Claude Desktop, Claude Code, Cursor and VS Code.

For a business, this could eventually support workflows where an authorised AI assistant can retrieve information from WordPress or perform specific approved tasks.

But this requires deliberate configuration.

It is not something that happens simply because WordPress has been updated.

Does this improve SEO?

This is an important point.

The WordPress AI Client, Connectors API, Abilities API and MCP Adapter are not direct Google ranking factors.

Installing them will not automatically improve your Google rankings.

They are development technologies.

However, they are part of a wider change in how websites and software can interact with AI.

That makes it increasingly useful for businesses to have websites with information that is:

• accurate
• clearly structured
• easy to understand
• technically accessible
• properly organised
• regularly maintained

These are good website practices regardless of AI.

Your website should not be built around the assumption that an AI system will rank it simply because you have added an AI feature.

Good technical SEO, useful content, accessibility, performance and a good user experience still matter.

Does this mean my website needs AI?

No.

This may be the most important message for business owners.

AI is useful when it solves a genuine problem.

It is not useful simply because it is new.

Before adding an AI plugin or custom AI feature, ask:

What problem are we trying to solve?
If there is no clear answer, you probably do not need the feature.

What information will the AI access?
Understand what data is being sent to an external service.

What permissions will it have?
An AI tool that can read information is very different from one that can modify or delete information.

Can a person review the result?
For important business information, human review should remain part of the process.

Is the plugin maintained?
AI integrations can depend on external services that change quickly. A plugin that is poorly maintained can become a liability rather than an advantage.

What should WordPress website owners do now?

There is no reason to panic and no reason to install every AI plugin available.

Instead, take a sensible approach.

Keep WordPress updated

Use supported versions of WordPress, themes and plugins.

Updates can contain security fixes, compatibility changes and new functionality.

WordPress 7.0 also changes the minimum PHP requirement to PHP 7.4, with PHP 8.2 or later recommended by WordPress for the release.

If your website is running an older PHP version, this is something your developer or hosting provider should check before updating WordPress.

Review your plugins

Remove plugins that are no longer needed.

For AI related plugins, check:

• who developed them
• when they were last updated
• what permissions they require
• what external services they use
• what information they send outside your website

Keep your website information accurate

AI systems can only work with the information they can access.

That makes accurate business information increasingly important.

Review your:

• service pages
• product information
• contact details
• business information
• FAQs
• author information
• company information
• internal links

Think about useful AI applications

Instead of asking:

"Should we add AI to our website?"

ask:

"Is there a repetitive or difficult task on our website that AI could genuinely help with?"

That gives you a much better starting point.

What is likely to matter most for businesses?

The most important change is not that WordPress has suddenly become an AI website platform.

It is that WordPress is creating common infrastructure that developers can build on.

The AI Client provides a standard way for WordPress code to communicate with AI models.

The Connectors API provides a standard framework for managing connections to external services.

The Abilities API provides a standard way to describe and execute specific WordPress functionality.

The MCP Adapter can connect selected WordPress abilities to compatible AI applications.

These pieces can work together, but they do not mean that every WordPress website automatically has AI capabilities.

That distinction matters.

What does this mean for the future of WordPress?

WordPress is making it easier for developers to build AI related functionality around the platform.

The WordPress Developer Blog has already demonstrated how the Abilities API, AI Client and MCP Adapter can be combined to build an AI powered WordPress plugin.

For website owners, this could lead to more useful AI features appearing in WordPress plugins and custom websites.

Some businesses may benefit from AI assisted administration.

Others may benefit from smarter search, automated workflows or tools that connect their WordPress website with other business systems.

Others may find that they do not need AI at all.

There is no single answer for every website.

The right question is not:

"How much AI can we put into our WordPress website?"

It is:

"Where can better technology make our website more useful for our customers and our business?"

Frequently asked questions about WordPress AI

What is the WordPress AI Client?

The WordPress AI Client is a built in, provider independent PHP API introduced in WordPress 7.0. It gives plugins a standard way to send prompts to AI models and receive results. WordPress Core does not include the AI providers themselves. Providers can be connected through provider plugins and the Connectors API.

Does WordPress 7.0 automatically make my website AI powered?

No. WordPress 7.0 provides the AI Client and related infrastructure, but updating WordPress does not automatically add AI features to your website. A plugin or custom development needs to use these APIs to provide a particular AI feature.

What is the WordPress Connectors API?

The Connectors API was introduced in WordPress 7.0. It provides a standard framework for registering and managing connections to external services, with an initial focus on AI providers. WordPress 7.0 includes featured connectors for Anthropic, Google and OpenAI, available through the Settings > Connectors screen.

What is the WordPress Abilities API?

The Abilities API was introduced in WordPress 6.9. It provides a standard way for WordPress, plugins and themes to register specific functions that other systems can discover and use. Abilities can define their inputs, outputs and permissions, making them useful for automation and AI applications as well as other WordPress integrations.

What is MCP in WordPress?

MCP stands for Model Context Protocol. The WordPress MCP Adapter is an official package from the WordPress AI Building Blocks project. It connects WordPress Abilities with MCP so compatible AI applications can discover and use selected WordPress functionality.

Can AI control my WordPress website?

Not automatically. The MCP Adapter can expose selected WordPress Abilities as tools for compatible AI applications. Developers decide which Abilities are exposed, while the Abilities themselves can have permission checks controlling who can use them. An AI application therefore does not automatically receive unrestricted access to a WordPress website.

Will these WordPress AI updates improve my Google rankings?

Not directly. The AI Client, Connectors API, Abilities API and MCP Adapter are WordPress development technologies. They are not presented as Google ranking factors. Adding these technologies to a website does not automatically improve its search rankings.

Should I install an AI plugin on my WordPress website?

Not simply because WordPress now supports AI related functionality. First consider what problem the plugin is intended to solve, what information it accesses, which external services it uses, what permissions it requires and whether it is properly maintained.

Does WordPress send my website content to AI automatically?

No. The AI Client provides the ability for WordPress code to make AI requests, but an AI request has to be made by code and a suitable AI provider needs to be configured. Updating WordPress does not by itself mean that your website content is being sent to an AI provider.

Can Web Choice help with WordPress AI integrations?

Yes. Web Choice can help with WordPress website design, development, WooCommerce, maintenance, performance, security, integrations and custom functionality. If you are considering AI for your WordPress website, we can help you assess where it could be useful and how it could fit into your existing website.
