nuxt-ai-ready

Tested against nuxt-ai-ready 2.4.1 plus its unreleased fixes on main, on Nuxt 4.5 and Node 24. The module converts rendered pages to Markdown with mdream and publishes llms.txt, llms-full.txt, and .md twins. Optional parts add MCP tools, WebMCP tools, and a runtime page index. Config key: aiReady. Docs: https://nuxtseo.com/ai-ready

Setup

The package installs @nuxtjs/robots and @nuxtjs/sitemap and loads them as module dependencies. Configure them with the robots and sitemap keys.

pnpm add nuxt-ai-ready

Set site.url. Canonical URLs, Link headers, and /.well-known/ai-catalog.json use it. Prerender the pages you want in llms-full.txt and in the page index (nuxi generate, or nitro.prerender.routes). A page visit in dev or production does not index anything.

Automatic behaviour

With no aiReady config, the module adds:

• /llms.txt: site name, description, resource links, and a ## Pages list. In dev it lists sitemap routes without titles.
• /llms-full.txt: the full Markdown of each prerendered page. Only prerendered pages go in the static file.
• A .md twin per page. /about becomes /about.md, and / becomes /index.md. Paths under /api and /_ get none.
• Accept negotiation: a request that prefers text/markdown, or a known AI bot user agent, gets a 307 to the .md URL.
• <link rel="alternate" type="text/markdown"> and <link rel="describedby" href="/llms.txt"> in HTML, plus matching Link headers.
• /sitemap.md, and a ## Sitemap footer on every generated .md page. Set sitemapMd: false to remove both.
• Nuxt Content v3 page collections: the .md route serves the source Markdown, not converted HTML. Set contentSource: false to convert HTML.
• Agent skills: every skills/<name>/SKILL.md in the project root or a local layer is published at /.well-known/agent-skills/, at /skills/<name>/SKILL.md, and in llms.txt. With one skill it is also served at /SKILL.md. Set agentSkills: false to publish nothing.

Off by default: Content Signals, MCP, WebMCP, runtime sync, cron, and the database.

Common tasks

Add llms.txt sections. notes renders before the first heading:

export default defineNuxtConfig({
  aiReady: {
    llmsTxt: {
      sections: [{ title: 'API Reference', links: [{ title: 'REST API', href: '/docs/api', description: 'API docs' }] }],
      notes: 'Built with Nuxt AI Ready',
    },
  },
})

Remove an element from the Markdown on every path, build and runtime. Put it in mdreamOptions; the defaults minimal and clean stay on:

export default defineNuxtConfig({
  aiReady: { mdreamOptions: { filter: { exclude: ['.author-bio'] } } },
})

Change the Markdown text. The Nitro hook covers runtime .md responses, prerendered .md files, llms-full.txt, and indexed pages. ctx.isPrerender is true only during prerendering:

// server/plugins/markdown.ts
export default defineNitroPlugin((nitroApp) => {
  nitroApp.hooks.hook('ai-ready:page:markdown', (ctx) => {
    ctx.markdown += '\n\nSee /support.'
  })
})

Allow Content Signals. An omitted permission renders as no:

export default defineNuxtConfig({ aiReady: { contentSignal: { search: true } } })
// robots.txt: Content-Signal: ai-train=no, search=yes, ai-input=no

MCP: install @nuxtjs/mcp-toolkit and add it to modules. The module then registers list_pages, search_pages, and get_page_markdown at /mcp. MCP needs a running server; nuxi generate output cannot host it.

WebMCP: set webmcp: true. This registers the same three tools in the browser and auto-imports useWebMcpTool() and useWebMcpSupported(). Without webmcp, those composables are not defined.

Runtime indexing, database drivers, Cloudflare D1, and the server query helpers: see references/runtime-indexing.md.

Traps

• The same edit in both hooks applies twice. During prerendering the Nitro ai-ready:page:markdown hook runs, then the Nuxt hook of the same name. Put an edit in one of them, not both.
• Content source pages skip conversion hooks. A Nuxt Content page ignores mdreamOptions and both Nitro hooks.
• Dev has no page data. Query helpers, MCP tools, and search return empty results in nuxi dev. Test with nuxi build and node .output/server/index.mjs.
• Response caching turns negotiation off. An ISR, swr, or cache route rule without varies: ['accept', 'sec-fetch-dest', 'user-agent'] serves HTML to Markdown clients. The .md URL still works. For a CDN that caches by URL only, set contentNegotiation: false.
• Emptying ctx.markdown does not hide a page. It drops the body from llms-full.txt. The URL stays in llms.txt and in the index. Use sitemap.exclude for discovery, and access control for private pages.
• A project skills/ folder is public. Agent skills discovery publishes it with no opt in. Rename the folder with agentSkills.dir, or set agentSkills: false.
• The same hook name exists twice. ai-ready:page:markdown is a Nuxt hook (nuxt.config hooks, prerender only) and a Nitro hook (nitroApp.hooks, every HTML conversion). They receive different context. The Nitro ctx.event is undefined when indexing runs outside a request.
• database: false conflicts with runtimeSync and cron. The build fails and names the option.

Version limits

• v2 removed IndexNow. The indexNow option and /__ai-ready/indexnow no longer exist. Submit URLs from the ai-ready:page:indexed Nitro hook: https://nuxtseo.com/docs/ai-ready/advanced/indexnow
• v1 renamed these. Do not write the old form:

Config

• llmsTxt.markdownLinks (false): link page entries in llms.txt to their .md twins.
• describedby (true): the describedby link tag and header.
• tools.<listPages|searchPages|getPageMarkdown>.<mcp|webmcp>.enabled: attach a built in tool to one transport only.
• autoI18n (true): with @nuxtjs/i18n, adds hreflang Link headers and a languages section in llms.txt.
• Other options: https://nuxtseo.com/docs/ai-ready/api/config

Debug

• curl -H 'Accept: text/markdown' -D - -o /dev/null <url> must return 307 with Location: <path>.md. A 200 means a cache rule turned negotiation off.
• /__ai-ready__/debug.json exists in dev, or with debug: true.
• Nuxt DevTools has an AI Ready tab.
