Validated OpenAI-compatible product feed for ChatGPT product discovery (ACP), plus catalog API, MCP server and UCP discovery for AI agents.

KaliCart Bridge – Product Feed for ChatGPT & AI Agents

Make your WooCommerce catalog ready to be read and verified by AI shopping systems.
KaliCart Bridge gives you an immediate catalog-readiness report inside WooCommerce: it identifies products with missing images, brand, usable description, category, price or SKU, and links you directly to the native Products screen to fix them. It then exposes your live catalog in a structured form for AI agents and can generate a validated product feed ready for ChatGPT merchant submission.
No LLM runs on your site. No cloud service or customer data is sent anywhere by default. Prices, availability and product changes remain live on your WooCommerce store.
The plugin does not promise traffic, ChatGPT placement or merchant approval. It prepares and exposes your catalog; OpenAI controls access to its own shopping surfaces and delivery channel.

For developers and AI integrations
What it does:
<ul>
<li>Exposes a <code>/discovery</code> endpoint — the single entry point any agent needs to understand your catalog</li>
<li>Provides <code>/catalog/search</code>, <code>/catalog/products</code>, <code>/catalog/product/{id}</code>, <code>/catalog/categories</code> endpoints</li>
<li>Exposes a Model Context Protocol (MCP) server at <code>/wp-json/kalicart/v1/mcp</code> (JSON-RPC 2.0) so MCP-capable agents can call the catalog as tools — same data as the REST endpoints, no API key</li>
<li>Gives AI chatbot and assistant builders a structured catalog source to ingest or call, instead of scraping product pages</li>
<li>Computationally normalizes product data: prices (min/max for variables, sale %, discount), stock, gender inference, color family mapping, size type detection</li>
<li>Exposes WooCommerce shipping-zone policy for agent reasoning; checkout remains the final authority for exact destination/cart shipping cost</li>
<li>Exposes active product/category-compatible coupons as conditional checkout savings; coupons never replace the catalog price</li>
<li>Category tree nodes include direct <code>products_url</code> and <code>search_url_template</code> fields so agents can navigate without constructing URLs manually</li>
<li>Dashboard issue cards and suggestions link to filtered product lists for direct remediation</li>
<li>Uses your merchant taxonomy — no global remapping, products stay in your WooCommerce categories</li>
<li>Injects a <code>&lt;link rel="kalicart-agent"&gt;</code> in your site <code>&lt;head&gt;</code> for agent auto-discovery</li>
<li>Adds an &#8220;agent ready&#8221; badge in the footer</li>
<li>Injects <code>Allow: /wp-json/kalicart/</code> in <code>robots.txt</code></li>
<li>Generates <code>/kalicart-sitemap.xml</code> linked from the WP sitemap index</li>
<li>Shows a catalog health dashboard in wp-admin with quarantine tracking and improvement suggestions</li>
</ul>
What it does NOT do:
<ul>
<li>No LLM calls</li>
<li>No cloud dependency for core functionality</li>
<li>No data sent anywhere outside your server by default — the only optional exception is the Federated Catalog feature (see &#8220;External services&#8221; below), which you turn on explicitly</li>
<li>No API key required for public endpoints</li>
</ul>
Normalization engine:
<ul>
<li>Price: regular, sale, current, discount %, currency — variable products get min/max ranges</li>
<li>Stock: status, in_stock bool, quantity if managed, backorder policy</li>
<li>Gender: inferred from <code>pa_gender</code> attribute, category paths, tags, product name (multilingual keywords: IT/EN/FR/DE/ES)</li>
<li>Color: mapped to 13 color families via keyword matching on <code>pa_color</code>/<code>pa_colore</code> and product metadata</li>
<li>Size: detected from <code>pa_size</code>/<code>pa_taglia</code>, type auto-detected (clothing S/M/L, numeric EU, shoes EU half-sizes)</li>
</ul>
Catalog health / quarantine:
Products are scored 0–100 based on: title quality, description length, category assignment, price validity, image presence and SKU presence. Quarantine is reserved for blocking computability issues: ambiguous/too-short titles, missing or very short descriptions, missing real categories, and missing or zero prices. Missing images and SKUs remain clickable improvement suggestions but do not quarantine products.
Checkout sessions (optional):
When enabled in WP Admin → KaliCart → Settings, agents can create checkout sessions containing one or more products. Each session returns cart_url (lands on WooCommerce cart for review) and checkout_url (goes directly to checkout). Sessions expire after 30 minutes. No OAuth, no PII, no payment on the agent side.
Model Context Protocol (MCP) endpoint:
The same read-only catalog is also exposed as an MCP server at <code>/wp-json/kalicart/v1/mcp</code> (JSON-RPC 2.0 over HTTP POST). MCP-capable agents and assistants connect to it and call the catalog as tools: <code>search_products</code>, <code>list_products</code>, <code>get_product</code>, <code>list_categories</code>, <code>get_meta</code>. It is read-only and needs no authentication, exactly like the public REST endpoints — it adds a second transport, not new data. No LLM, no external calls. Checkout and payment are never exposed over MCP.
<h3>ChatGPT Product Discovery Feed</h3>
<ol>
<li>Configure and generate. Set your return policy URL and target countries (derived from your WooCommerce selling locations); optionally set a brand fallback for own-label stores. The plugin validates every row against the OpenAI Product Feed specification: incomplete store configuration blocks generation entirely, products without image or brand are excluded and counted, and a failed run never destroys the last valid feed.</li>
<li>Apply at chatgpt.com/merchants. Application and approval are required and decided by OpenAI.</li>
<li>Deliver after approval. Upload the generated file (stable filename, <code>jsonl.gz</code> supported) on the delivery channel OpenAI assigns. The plugin regenerates a full daily snapshot via WP-Cron.</li>
</ol>
No acceptance or visibility is guaranteed by the plugin: approval, delivery access and final ranking are determined by OpenAI.
<h3>External services</h3>
This plugin works fully standalone. It connects to one external service only if you explicitly opt in by activating the optional Federated Catalog feature in WP Admin → KaliCart Bridge.
Service: KaliCart Global (https://dashboard.kalicart.com)
When data is sent: Only when an administrator clicks &#8220;Activate Federated Catalog&#8221; (and, symmetrically, &#8220;Revoke consent&#8221;). Nothing is sent automatically, on activation, or in the background. With the feature off, the plugin makes no external requests.
What is sent: A single value — your site&#8217;s public URL (e.g. https://yourstore.com). On revoke, the same URL is sent to withdraw. No customer data, orders, personal data, credentials, or API keys are ever transmitted.
What the service does: The URL tells KaliCart Global your store wishes to be discovered. KaliCart Global then periodically reads your already-public catalog (the same data exposed by the Bridge&#8217;s public REST endpoints) and includes it in federated agent search. It only reads; it never writes to your store. Revoking stops this and parks your catalog.
