Choose a direct Claude API integration when you need a custom WordPress feature and have developers to build and maintain it. Choose the WordPress.org Anthropic provider plugin when you want to use Claude through WordPress’s PHP AI Client and its supported setup fits your site. If you run an eligible WordPress.com site and want Claude to work with its content through an approved connection, consider the separate WordPress.com connector. These are different routes—not three versions of the same plugin.

What are the three ways to connect Claude and WordPress?

Build with the Claude API

The Claude API is a building block, not a ready-made WordPress plugin. A developer can use it in a custom plugin, theme feature, or external application that sends requests to Anthropic. Anthropic’s official SDKs help with tasks such as authentication, request formatting, and error handling. This approach suits a custom workflow or user experience, but your team is responsible for implementation, credentials, permissions, failures, updates, and ongoing maintenance. The appropriate platform depends on factors such as infrastructure, feature availability, compliance needs, and pricing preferences, as Anthropic notes in its API overview.

Install the WordPress.org Anthropic provider

The AI Provider for Anthropic connects Anthropic to WordPress’s PHP AI Client. Its directory listing describes text generation, function calling, extended thinking, automatic provider registration, and dynamic discovery of available models. You still need an Anthropic API key; the provider plugin does not remove the need for API credentials or usage charges.

The listing states PHP 7.4 or higher. For WordPress 6.9, it says the wordpress/php-ai-client package is required; for WordPress 7.0 and above, it says no additional changes are required. Check the current listing and your site’s version before installing, since compatibility requirements can change.

WordPress’s PHP AI Client guidance describes the Connectors screen as a central place to configure providers, including entering API keys. It also explains how plugins can register a service connector and use the AI Client in their functionality. Check whether the relevant screen and setup are available for your WordPress version.

Connect Claude to a WordPress.com site

The WordPress.com connector for Claude is a hosted WordPress.com connection, not a general plugin for any self-hosted WordPress site. Its listing says Claude can find posts, check statistics, draft content, update pages, and access other site resources. It describes OAuth 2.1 access limited to resources a user approves, with every change confirmed by the user.

The listing identifies Automattic (WordPress.com) as the maker, says the connector was added in January 2026, and specifies paid WordPress.com plans and sites connected to Jetpack AI or Complete. Availability and scope are listing details that may change, so check the connector page and your site’s eligibility.

Which route fits your needs?

Your situation Best starting point Main trade-off
You need a custom feature or workflow and have developer support. Direct Claude API integration Maximum control, but your team builds and maintains the connection. Anthropic API overview.
You want Claude through WordPress’s AI Client and the provider’s features and compatibility fit. WordPress.org Anthropic provider plugin A quicker starting point, but it requires an Anthropic API key and suitable WordPress/PHP setup. Plugin listing; WordPress AI Client guidance.
You want Claude to work with an eligible WordPress.com site. WordPress.com connector Guided OAuth access and user-confirmed changes, subject to plan and site eligibility. Connector listing.

Before settling on a route, compare how much customization you need, who will maintain it, whether your hosting and WordPress version support it, how credentials and permissions work, what data is handled, and what API or plan costs apply. WordPress’s AI Client educational material describes cloud providers as processing AI requests on external servers and identifies cost, privacy, and setup as provider-selection considerations.

What should you check before connecting Claude?

Credentials and access

For a custom API integration or the provider plugin, protect the API key and limit who can configure or invoke AI features. If a feature can publish, edit, or otherwise change site content, validate that the person requesting the action has the required WordPress permissions. Review the code and configuration rather than assuming that a plugin listing certifies every security or access-control detail.

Prompts, responses, and retention

Find out whether prompts and responses are logged or stored by the integration, the site, and the service processing the request. Anthropic’s API retention documentation describes zero-data-retention and HIPAA-ready arrangements for eligible API usage and distinguishes Anthropic-operated platforms from partner-operated services. Those API-level arrangements do not establish that a particular WordPress plugin or the WordPress.com connector has zero retention or HIPAA status. Confirm eligibility, account settings, and the current terms for the specific route and processor.

Is “Claude Plugins API” the same as a WordPress plugin?

No. Anthropic’s Plugins API manages plugins in Claude Enterprise organizations, including versions and availability. It is separate from the Claude model API and from WordPress plugins.
