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. #### Guides and help * The plugin’s page: [athplugins.com/plugins/webmcp](https://athplugins.com/plugins/webmcp/) * Step by step guides, in English and Greek: [athplugins.com/docs/webmcp](https://athplugins.com/docs/webmcp/) #### Who makes it ATHPlugins is the plugin studio of [ATH Development](https://ath.dev), a web agency in Greece that builds and looks after WooCommerce stores. ## Screenshots [⌊The WebMCP check list, which also reads your trial token.⌉⌊The WebMCP check list, which also reads your trial token.⌉[ The WebMCP check list, which also reads your trial token.

Instead of reading the screen, an agent calls a tool such as product search and gets a clear answer. ### How do I add WebMCP to WordPress or WooCommerce? Install this plugin, switch it on in Settings > Agent Tools (WebMCP) and choose the tools. There is no code to write. For real visitors you also paste a free trial token from Chrome. ### Is WebMCP the same as MCP? They are related. An MCP server connects an AI app to a service from outside. WebMCP tools live in the web page and run in the visitor’s own browser session. ### Do I need a trial token? For now, yes, for real visitors. WebMCP is a browser experiment, an origin trial, and a browser offers it to your site only with a valid token for your address. Tokens are free and expire, and the check list shows you the date. When we last checked, on 31 October 2026, the Chrome trial covered Chrome 149 to 162 and ended on 30 March 2027. If you are only trying the plugin, you can turn on the testing flag in your own Chrome: chrome://flags/#enable-webmcp-testing. ### Which agents use this? Support is still arriving and changes often. Google has said that Gemini in Chrome will support WebMCP. Check the guides on our site for what we know today. ### Can an agent buy something without the customer knowing? No. No tool can place an order. The tools stop at the checkout page, where the customer reviews the order and pays. If you switch on the cart tools, the visitor sees a message on the page for every change. ### Is this the same as MCP for WooCommerce? No. WooCommerce MCP lets the store owner manage the store from an AI app, with an admin key. WebMCP tools are for the shopper’s own agent, in the shopper’s browser, with what the shopper is allowed to see. ### Does it help my position in Google? We have seen nothing from Google that says so, and we do not promise it. ### Does the plugin send data anywhere? The plugin itself calls no outside service, and tools answer from your own site. The answers go to the agent the visitor uses in their own browser, and that agent may send them to its own provider, as with anything it reads on the screen. Only tick what you are happy for a visitor’s agent to read. Add a line about AI agents to your privacy policy if you switch on order tracking. ### Can developers change the tools? Yes, with the filters `athwmcp_active_tools`, `athwmcp_store_info`, `athwmcp_shipping_options`,` athwmcp_payment_options` and `athwmcp_track_order`. A tool’s use also fires the event `athwmcp:tool` on the document. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “ATH Agent Tools for WebMCP” is open source software.
