We check WebMCP tools, accessibility tree quality, schema, and layout stability, then give you copy-paste fixes. An agent-ready website exposes WebMCP tools, a clean accessibility tree, and stable layout so AI agents from Chrome, ChatGPT, and other assistants can read and act on it.

Copied to clipboard! ## What the agentic readiness checker tests AI agents are starting to browse the web on people's behalf: Chrome's built-in agent, ChatGPT operators, and other autonomous assistants now read pages and take actions on them. This free WebMCP and agentic browsing checker reads the source of any URL you enter and grades it across the four areas that decide whether an agent can use your page. ### WebMCP integration Detects declarative form and navigation tools, imperative WebMCP registration, and whether every tool parameter is described so an agent can call it. ### Accessibility tree Checks the structure agents rely on: html lang, image alt text, accessible names on fields and controls, semantic landmarks, and a single h1. ### Layout stability (CLS) Flags images and embedded media without explicit dimensions, the main cause of layout shift that breaks an agent mid-action. ### Discoverability Reminds you to publish an llms.txt at your domain root so agents and answer engines know what your site is and where to look. ## Agentic browsing and WebMCP, in brief Agentic browsing is when an AI agent navigates and acts on a site for a user instead of just reading it, and Chrome Lighthouse now scores how ready your page is for it. WebMCP is the browser standard that makes it work: you expose structured tools to agents either declaratively (annotating forms and links with data-toolname and data-tooldescription) or imperatively (registering actions through navigator.modelContext). This checker reads your page and tells you whether those tools, and the structure around them, are in place. For the full implementation walkthrough and a step-by-step on making a page agent-ready, read our [WebMCP agent-ready website guide](/blog/webmcp-agent-ready-website-guide/). ## Agentic readiness vs traditional SEO and AEO Agentic readiness is the newest layer of a bigger shift. Traditional SEO gets you ranked in Google, answer engine optimization (AEO) gets you cited in AI answers, and agentic readiness lets agents actually act on your page. The good news is that the signals reinforce each other: clean structure, schema, and fast stable rendering help all three. To see how your content reads to answer engines, try our [free SEO audit tool](/free-seo-audit-tool/) and [blog SEO checker](/free-blog-seo-checker/). To find out whether AI engines already cite your brand, run the [AI visibility audit](/ai-audit/). ## Want this done for you? Snezzi is a done-for-you AI SEO agency.

Chrome Lighthouse added an Agentic Browsing category that measures how readable and actionable your page is to these agents, using the Chrome DevTools Protocol and the live accessibility tree. WebMCP is a browser standard that lets a page expose structured tools to AI agents. Declarative tools annotate existing forms and navigation with attributes like data-toolname and data-tooldescription, while imperative tools register actions in JavaScript via navigator.modelContext or document.modelContext. This tells agents exactly what actions a page supports and what parameters they take. Lighthouse runs in a live Chrome instance and reports a fractional score (the ratio of agentic-readiness checks passed) using the DevTools Protocol WebMCP domain and the rendered accessibility tree. This tool fetches the page source from the URL you enter, so it cannot evaluate runtime-registered tools, computed accessibility names, or layout shifts that only happen after rendering. Treat this checker as a fast source pre-check, not the authoritative score. Start by exposing WebMCP tools on your highest-intent forms and navigation, give every tool a clear name and description, and ensure each input has an accessible label. Then fix accessibility tree basics (html lang, image alt text, one h1, semantic landmarks), set explicit width and height on media to avoid layout shift, and publish an llms.txt at your domain root. Finally, run the official Chrome Lighthouse Agentic Browsing audit to confirm. Enter your URL above and the checker grades it across four areas: WebMCP tool integration, accessibility tree quality, layout stability, and discoverability. A high pass ratio means agents like Chrome's built-in agent and ChatGPT operators can read your page structure and act on it. A low ratio flags exactly what to fix first. A WebMCP validator checks whether a page exposes WebMCP tools correctly: declarative form and navigation tools annotated with data-toolname and data-tooldescription, or imperative tools registered through navigator.modelContext. This checker validates that those tools exist and that every parameter has an accessible description, so agents can call them without guessing. An agent-ready website is one that AI agents can understand and operate, not just one humans can read. In practice that means clear WebMCP tools on key actions, a clean accessibility tree (labels, landmarks, a single h1), a stable layout with no surprise shifts, and an llms.txt that tells agents what your site is about. They overlap heavily. The same signals that make a page agent-ready (clean structure, schema, accessible labels, fast and stable rendering) also help answer engine optimization (AEO) and AI visibility in ChatGPT, Perplexity, and Google AI Overviews. Agentic readiness is the action layer; AEO is the citation layer. Fixing one usually lifts the other. An AI visibility checker measures whether AI answer engines already cite your brand. This checker measures whether the page itself is structured for agents to read and act on. Use this to fix the page, then run our AI visibility audit to track whether citations follow. Yes.
