KZB Studio

<p>KZB AI Cart Assistant for WooCommerce connects your store to AI systems using the open <strong>Model Context Protocol (MCP)</strong>. It also adds an optional AI-powered chat widget to your storefront, powered by the <strong>WordPress AI Client</strong> built into WordPress 7.0.</p>
<p><strong>The guiding principle: automation stops at the cart.</strong> The plugin never initiates checkout or processes payments — those actions always require a human.</p>
<h4>What the free version includes</h4>
<ul>
<li><strong>MCP server</strong> — 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><strong>Storefront chatbot</strong> — floating chat widget powered by the WordPress AI Client; customers can ask product questions and add items to their cart through conversation</li>
<li><strong>Bearer token authentication</strong> — per-user tokens that let an AI agent act on a specific customer’s behalf</li>
<li><strong>My Account integration</strong> — customers can generate and revoke their own tokens from the My Account page</li>
<li><strong>Admin panel</strong> — category filters, security limits (max quantity, max cart value), token management, and an audit log of every AI action</li>
<li><strong>Privacy-first</strong> — respects the Global Privacy Control (GPC) signal; no API keys are stored by the plugin</li>
</ul>
<h4>Pro version</h4>
<p>The <strong>KZB AI Cart Assistant Pro</strong> extension unlocks additional MCP tools and support for variable (configurable) products:</p>
<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>
<p>The Pro extension is available at <a href="https://kzbstudio.pl" rel="nofollow ugc">kzbstudio.pl</a>.</p>
<h4>MCP Server</h4>
<p>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.</p>
<p>Typical agent flow:</p>
<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>
<p>This plugin connects to external AI services <strong>only when the chatbot is enabled and an AI provider is configured in WordPress Settings <span aria-hidden="true" class="wp-exclude-emoji">→</span> AI</strong>. No data is sent to any external service when the chatbot is disabled (the default state).</p>
<p><strong>WordPress AI Client</strong><br />
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 <strong>Settings <span aria-hidden="true" class="wp-exclude-emoji">→</span> AI</strong> in your WordPress admin — this plugin does not communicate directly with any AI provider.<br />
Data sent: conversation messages, product catalog summary, cart context.</p>
<p>No data is ever sent to the plugin author’s servers.</p>


KZB AI Cart Assistant for WooCommerce

Allow AI agents and a storefront chatbot to browse your product catalog and add items to customers' carts. Payment is always completed by a human.

Respira for WordPress

<p>Inhale: MCP Abilities is a small, focused utility that solves one problem: the default WordPress MCP server (provided by the official MCP Adapter plugin) does not expose any registered abilities by default. Site administrators have to write PHP filters to opt each ability into the public MCP surface.</p>
<p>This is the workaround pattern documented in WordPress contributor blog posts and developer guides since the MCP Adapter shipped. Inhale: MCP Abilities replaces the PHP-filter workaround with a simple settings page.</p>
<p>Once installed and activated, you’ll find a new page at Settings > Inhale: MCP Abilities where you can check off the abilities you want exposed to your default MCP server.</p>
<h4>What the Inhale: MCP Abilities plugin does</h4>
<ul>
<li>Lists every registered WordPress ability across all active plugins and themes</li>
<li>Lets you select which abilities are exposed to the default MCP server with simple checkboxes</li>
<li>Shows annotation metadata (read-only, destructive, idempotent) on each ability so you can make informed decisions</li>
<li>Requires explicit confirmation when you inhale an ability marked as destructive</li>
<li>Provides connection info for popular MCP clients (Claude Desktop, Cursor, Claude Code)</li>
<li>Respects each ability’s own permission_callback. The Inhale: MCP Abilities plugin controls visibility, not authorization.</li>
</ul>
<h4>What the Inhale: MCP Abilities plugin doesn’t do</h4>
<ul>
<li>Inhale: MCP Abilities does not run any MCP servers, transports, or authentication. Those are handled by the official MCP Adapter plugin, which the Inhale: MCP Abilities plugin extends.</li>
<li>Inhale: MCP Abilities does not register any abilities of its own. It only toggles visibility of abilities other plugins have registered.</li>
<li>Inhale: MCP Abilities does not phone home, collect telemetry, or make external network requests.</li>
</ul>
<h4>Requirements</h4>
<ul>
<li>WordPress 6.8 or later (Abilities API in core since 6.9; 6.8 requires the Abilities API plugin)</li>
<li>PHP 7.4 or later</li>
<li>The official WordPress MCP Adapter plugin installed and active</li>
</ul>
<h4>About MCP</h4>
