ATH Agent Tools for WebMCP

Description

AI agents and shopping assistants are starting to shop for people inside the browser, the idea often called agentic commerce. Without help they read the screen and guess where to click. WebMCP (Web Model Context Protocol) is a proposed web standard, from the Chrome team and others, that lets a site tell them clearly what it can do.

This free plugin adds WebMCP to WordPress and WooCommerce, with no code to write. It offers the tools of your site and your store to the AI agent in the visitor’s browser, so your store is agent-ready: products, prices, stock, shipping and payment through clear tools.

Ελληνικά: Το δωρεάν WebMCP plugin για WordPress και WooCommerce. Κάντε το site και το eshop σας έτοιμο για τους AI βοηθούς (AI agents) του browser. Οι βοηθοί βρίσκουν προϊόντα, τιμές, απόθεμα, μεταφορικά και τρόπους πληρωμής, χωρίς να μαντεύουν από την οθόνη. Εσείς επιλέγετε κάθε εργαλείο και η πληρωμή μένει πάντα στον πελάτη. Το plugin έχει ελληνικό περιβάλλον.

An honest word about today

WebMCP is an experiment that can still change. Chrome and Edge offer it through free trial tokens, Safari and Firefox do not, and few agents use it so far. Setting it up now means your store is ready when more of them do. Do not expect extra sales from it yet.

Tools that only read

Ticked by default, and offered only after you switch the plugin on. They show what any visitor can already see.

• Store information: name, language, currency, main pages, and a note you write for agents (delivery times, returns, how to reach you).
• Search the site and read a page: public pages and posts, so an agent answers from what you wrote. Password protected content is refused.
• Search products: by words, category, price, stock and offers. Hidden products are never returned.
• Product details: price, stock, description, options such as size and colour, and the price of a chosen option.
• Product categories.
• Shipping options: the methods for a country and postcode, with cost and free shipping limit.
• Payment options: the methods that are on, and the fee of cash on delivery when you use our free ATH COD plugin.
• View the cart: the visitor’s own cart and totals.

Tools you switch on yourself

• Add to cart and change the cart. The visitor sees a message on the page for every change.
• Open the checkout. It takes the visitor to the checkout page. It fills in nothing.
• Track an order. Needs the order number together with the email or phone of the order. Returns the status and the tracking number, never an address. Repeated wrong tries are blocked. It reads tracking numbers from our free and paid courier plugins (ACS, ELTA Courier, Courier Center, Geniki Taxydromiki, SVUUM) and from the WooCommerce Shipment Tracking data.

What an agent can never do

• Place or pay for an order.
• See another customer’s cart, address or account.
• Change anything in your site or your admin.

Cart tools go through WooCommerce’s own Store API, in the visitor’s own session, so they can do only what the visitor could do by clicking. The plugin adds no way to write to your site.

Light on your site

• Visitors whose browser does not have WebMCP download one file of a few hundred bytes and nothing else happens.
• No extra database queries on ordinary pages, no tables, no logs, no calls to outside services. One small option.
• Works with page caching.

See when agents use your site

An option, off by default, sends an event with the tool’s name to Google Tag Manager when a tool is used. Never what was asked.

For your setup

• A check list tells you what is missing and reads the trial token you paste: which address it is for and when it expires.
• A test screen runs every tool and shows exactly what the agent receives.
• Works without WooCommerce too, with the tools for pages and posts.
• High-Performance Order Storage (HPOS), classic and block checkout.
• PHP 7.4 to 8.5.
• English and Greek included.
