Question 1

What is the Model Context Protocol (MCP) and how does it change WordPress development?

Accepted Answer

The Model Context Protocol (MCP) acts as a translation layer that allows AI agents, like Claude or Cursor, to move beyond simply talking about a website to actually interacting with its environment. By using an MCP adapter, the AI can "see" the WordPress install and perform tasks such as updating plugins, scaffolding themes, or querying database values through natural language. This shifts the developer's role from manual clicking and "glue code" writing to intent-based orchestration.

Question 2

Why does the AI see a "blank slate" even after the MCP adapter is connected?

Accepted Answer

The WordPress MCP adapter is built with a "security-first" mindset, meaning it exposes zero functionality by default to prevent unauthorized or accidental changes. To give an AI agent access to specific tools, a developer must explicitly register an "Ability" and set a specific metadata flag—`mcp` with `public` set to `true`. Without this intentional opt-in, the AI will not have any tools in its "toolbelt," ensuring the developer maintains total control over the site's surface area.

Question 3

How does the Abilities API function within this architecture?

Accepted Answer

The Abilities API, introduced in WordPress 6.9, serves as a standardized way to register what a site can actually do. When a developer registers an ability using `wp_register_ability`, they provide a unique name, a JSON input schema to tell the AI what data is required, a permission callback for security checks, and an execution callback which is the actual PHP logic. The MCP adapter then takes these registered abilities and translates them into "Tools" that the AI can discover and trigger.

Question 4

What security measures should be taken when connecting an AI to a WordPress site?

Accepted Answer

Security relies on the principle of least privilege and secure authentication. Developers should use Application Passwords to create a secure handshake between the AI client and WordPress. It is highly recommended to create a dedicated "AI User" with limited roles (like Editor instead of Administrator) so the AI is physically incapable of performing high-risk actions like deleting plugins. Additionally, because AI can access sensitive customer data in environments like WooCommerce, developers must manage API scopes carefully to remain compliant with privacy regulations like GDPR.

Question 5

Can AI agents be used to manage WooCommerce stores through MCP?

Accepted Answer

Yes, WooCommerce currently offers a developer preview for MCP that maps core store operations—such as listing products, retrieving order details, and updating inventory—directly into the system. This allows for "Agentic Commerce," where an AI can perform complex bulk tasks, like applying a discount to a specific category of products, by communicating with existing WooCommerce REST controllers. This automation happens through the "front door" of application logic, ensuring that all standard data validation and permission checks remain active.
