What it can do
Tool names and descriptions exactly as the server reported them on Nov 7, 2026. The maker wrote them, not us; we show them as plain text.
check_store_ai_readinessChecks whether AI assistants and shopping agents can read an online store. Fetches the public store pages the user names, without running JavaScript. Returns the store's AI Shopping Readiness Index score if the store is in the Index, which AI crawlers its robots.txt allows, and w
check_ai_crawler_accessReads a site's robots.txt the way 9 crawlers do (Googlebot, Bingbot, Applebot, OAI-SearchBot, ChatGPT-User, Claude-SearchBot, Claude-User, PerplexityBot, Perplexity-User) and returns which may fetch the given page and the rule that blocks each one. Does not see CDN or firewall ru
check_page_readabilityFetches the public page at the given URL without running JavaScript and reports whether its main text is present in the HTML. Checks one page only. Use when the user asks whether a page's content can be read without JavaScript.
check_product_pageFetches one public product page without running JavaScript and reports whether the price and stock are in the HTML and which of six product structured data fields are present: price, availability, brand, identifier (gtin or sku), shipping details and aggregate rating. Use when th
check_page_visibilityRuns the xfix search check on one public page: fetches it without running JavaScript, checks robots.txt for 9 crawlers, measures mobile speed and reviews text, headings and title. Returns a score out of 100, a grade, coverage, any failed gates and the 5 biggest point losses with
get_page_visibility_resultReturns the result of an xfix search check started earlier, or its progress if it is still running.
lookup_index_scoreLooks up a store domain in the xfix AI Shopping Readiness Index and returns its published score and the fields shown on the public Index page, or says the store is not in the Index. Does not fetch the store.
check_ad_grants_websiteChecks a nonprofit's public website against the visible parts of Google's Ad Grants website policy: the domain serving the site itself, HTTPS, a findable mission, a physical address and registration number, real content on the key pages, working links and donate buttons, a mobile

Common questions
Is xfix safe?
It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (1.1.1) reached the registry today.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?
