KZB Studio

KZB AI Cart Assistant for WooCommerce connects your store to AI systems using the open Model Context Protocol (MCP). It also adds an optional AI-powered chat widget to your storefront, powered by the WordPress AI Client built into WordPress 7.0.
The guiding principle: automation stops at the cart. The plugin never initiates checkout or processes payments — those actions always require a human.
<h4>What the free version includes</h4>
<ul>
<li>MCP server — REST endpoints that expose your product catalog and allow authenticated AI agents to add products to a customer’s cart (<code>add_to_cart</code>) and view cart contents (<code>view_cart</code>)</li>
<li>Storefront chatbot — floating chat widget powered by the WordPress AI Client; customers can ask product questions and add items to their cart through conversation</li>
<li>Bearer token authentication — per-user tokens that let an AI agent act on a specific customer’s behalf</li>
<li>My Account integration — customers can generate and revoke their own tokens from the My Account page</li>
<li>Admin panel — category filters, security limits (max quantity, max cart value), token management, and an audit log of every AI action</li>
<li>Privacy-first — respects the Global Privacy Control (GPC) signal; no API keys are stored by the plugin</li>
</ul>
<h4>Pro version</h4>
The KZB AI Cart Assistant Pro extension unlocks additional MCP tools and support for variable (configurable) products:
<ul>
<li><code>remove_from_cart</code> — remove a specific product from the cart</li>
<li><code>update_cart</code> — change the quantity of a cart item (quantity 0 removes the item)</li>
<li><code>clear_cart</code> — empty the entire cart</li>
<li>Variable product support — add product variants by specifying a variation ID</li>
</ul>
The Pro extension is available at <a href="https://kzbstudio.pl" rel="nofollow ugc">kzbstudio.pl</a>.
<h4>MCP Server</h4>
AI agents discover the MCP endpoint via a <code><link rel="mcp-server"></code> tag automatically injected into your site’s <code><head></code>. The agent can then browse the product catalog (JSON-LD format) and call tools on behalf of an authenticated customer.
Typical agent flow:
<ol>
<li>Agent reads <code><link rel="mcp-server"></code> from your page HTML</li>
<li><code>GET /wp-json/kzbaca/v1/mcp</code> — reads available tools and the product catalog URL</li>
<li><code>GET /wp-json/kzbaca/v1/mcp/resources</code> — fetches the product list</li>
<li><code>POST /wp-json/kzbaca/v1/mcp/tools/add_to_cart</code> — adds a product (Bearer token required)</li>
<li>Agent returns the cart URL to the customer for payment</li>
</ol>
<h4>External Services</h4>
This plugin connects to external AI services only when the chatbot is enabled and an AI provider is configured in WordPress Settings → AI. No data is sent to any external service when the chatbot is disabled (the default state).
WordPress AI Client 
The storefront chatbot uses the WordPress AI Client (built into WordPress 7.0) to communicate with your configured AI provider. The AI provider and its privacy policy are managed in Settings → AI in your WordPress admin — this plugin does not communicate directly with any AI provider. 
Data sent: conversation messages, product catalog summary, cart context.
No data is ever sent to the plugin author’s servers.
