Pricing: https://agentreadychecklist.com/pricing.md (free). # Next.js Next.js App Router pages are Server Components by default, so content is in the HTML response, which meets AR-READ-01, and the framework adds no bot blocking, which meets AR-FIND-01. A sitemap, llms.txt, JSON-LD and markdown twin each need project code. Development mode exposes an MCP endpoint for coding agents, and none exists for a built site's visitors. ## At a glance Type [Framework](https://agentreadychecklist.com/vendors/by-type/framework/) Operator Vercel Homepage [nextjs.org](https://nextjs.org), answered HTTP 200 on 2026-11-05 Checklist rows 11 of 31 read: **2** supported, 8 partial, 1 no statement In the crawl 3 of 5,897 home pages counted on 2026-11-04.

Last read 2026-11-05 ## What it does for this layer - Next.js 16.4.5, published to npm on 2026-11-03 under the MIT licence, is also the doc version named in the Next.js docs index. primary source, 2026-11-03: [registry.npmjs.org/next](https://registry.npmjs.org/next), read 2026-11-05 - Next.js 16 was announced on 2025-10-21 with "Next.js Devtools MCP", a Model Context Protocol integration aimed at AI-assisted debugging. primary source, 2025-10-21: [nextjs.org/blog/next-16](https://nextjs.org/blog/next-16), read 2026-11-05 - In Next.js 16 and later the development server exposes an MCP endpoint at /\_next/mcp that gives coding agents the running app's errors, routes, logs and compilation issues; the next-devtools-mcp package connects an agent client to it. primary source: [nextjs.org/docs/app/guides/mcp](https://nextjs.org/docs/app/guides/mcp), read 2026-11-05 - Next.js docs state that "By default, layouts and pages are Server Components", rendered on the server and streamed to the client. primary source: [nextjs.org/docs/app/getting-started/server-and-client-components](https://nextjs.org/docs/app/getting-started/server-and-client-components), read 2026-11-05 - Calling notFound() renders the Next.js 404 page and injects a robots noindex meta tag into it, according to the API reference. primary source: [nextjs.org/docs/app/api-reference/functions/not-found](https://nextjs.org/docs/app/api-reference/functions/not-found), read 2026-11-05 - The middleware file convention is deprecated in Next.js 16 and renamed to proxy; proxy.ts is where a request header such as Accept can be read before routing. primary source: [nextjs.org/docs/app/api-reference/file-conventions/proxy](https://nextjs.org/docs/app/api-reference/file-conventions/proxy), read 2026-11-05 - Next.js has metadata file conventions, app/robots.ts and app/sitemap.ts, that generate /robots.txt and /sitemap.xml at build or request time. primary source: [nextjs.org/docs/app/api-reference/file-conventions/metadata/robots](https://nextjs.org/docs/app/api-reference/file-conventions/metadata/robots), read 2026-11-05 - A GET of https://nextjs.org/docs/llms.txt with the network user agent on 2026-11-05 returned a 51 KB text/plain index whose header names doc version 16.4.5. observed: [nextjs.org/docs/llms.txt](https://nextjs.org/docs/llms.txt), read 2026-11-05 - Next.js documentation pages carry "Copy for LLM" and "View Markdown" controls next to each article, seen on the MCP guide on 2026-11-05. observed: [nextjs.org/docs/app/guides/mcp](https://nextjs.org/docs/app/guides/mcp), read 2026-11-05 ## Products and plans | Product | What it is | Price | As of | | --- | --- | --- | --- | | Next.js | Open-source React framework with server rendering, static export and route handlers. | Free, open source; MIT licence; registry.npmjs.org/next | 2026-11-05 | ## Standards | Row | What it asks | Status | What the vendor's pages say | Source | | --- | --- | --- | --- | --- | | AR-FIND-01 | Do not block agents | supports | Next.js serves no robots.txt and adds no bot blocking unless the project defines app/robots.ts or public/robots.txt; the host WAF is separate. | nextjs.org/docs/app/api-reference/file-conventions/metadata/robots | | AR-FIND-03 | Sitemap listed in robots.txt | partial | A sitemap exists only when the project adds app/sitemap.ts or a static file. | nextjs.org/docs/app/api-reference/file-conventions/metadata/sitemap | | AR-FIND-04 | AI Catalog at .well-known | partial | Files under public/.well-known/ or a route handler can serve ai-catalog.json; nothing is generated. | nextjs.org/docs/app/api-reference/file-conventions/route | | AR-READ-01 | Answer in the initial HTML | supports | App Router layouts and pages are Server Components by default, so content is in the HTML response. | nextjs.org/docs/app/getting-started/server-and-client-components | | AR-READ-02 | Real HTTP status codes | partial | notFound() and not-found.js return a 404; unmatched routes 404 by default, missing records need notFound(). | nextjs.org/docs/app/api-reference/functions/not-found | | AR-READ-07 | Ship llms.txt | partial | No built-in llms.txt; a static file or route handler is needed. | nextjs.org/docs/app/api-reference/file-conventions/route | | AR-READ-08 | JSON-LD on key pages | partial | The JSON-LD guide shows rendering a script tag in a Server Component; nothing is added by default. | nextjs.org/docs/app/guides/json-ld | | AR-READ-09 | Advertise a markdown mirror | partial | generateMetadata can emit alternates with a text/markdown type; the project writes the markdown itself. | nextjs.org/docs/app/api-reference/functions/generate-metadata | | AR-ACT-03 | MCP over Streamable HTTP | no statement | The /_next/mcp endpoint serves coding agents in development; the docs describe no MCP server for a site's visitors. | nextjs.org/docs/app/guides/mcp | | CF-CONTENT-SIGNALS | Content-Signal line | partial | MetadataRoute.Robots has no Content-Signal field; a static robots.txt or route handler is needed. | nextjs.org/docs/app/api-reference/file-conventions/metadata/robots | | CF-MARKDOWN-NEGOTIATION | Markdown by Accept | partial | proxy.ts can read the Accept header and rewrite to a markdown route the project builds. | nextjs.org/docs/app/api-reference/file-conventions/proxy | ## Checks on its own site | Reading | Result | Date | Source | | --- | --- | --- | --- | | Cloudflare scan of nextjs.org | 27 of 100, band L1 Basic Web Presence | 2026-11-05 | isitagentready.com | | Home pages counted in the crawl | 3 of 5,897; Counted from the shared crawl of 2026-11-04 by generator meta tag in the home page HTML; the generator rule only sees tags whose name attribute comes first, so it undercounts | 2026-11-04 | agentreadychecklist.com/data/ | ## What it does not do - Next.js does not generate an llms.txt, a markdown twin or an MCP server for the sites built with it. - Next.js does not decide bot blocking or 404 behaviour at the edge; the host (Vercel or another) and its firewall settings do. ## Reading notes Version read from the npm registry on 2026-11-05; recipes for each requirement live on the nextjs-app-router platform page. ## Related pages on this site Recipes [Next.js](https://agentreadychecklist.com/platforms/nextjs-app-router/) ([checklist view](https://agentreadychecklist.com/platform/nextjs-app-router/checklist/)) Same recipe page [Medusa](https://agentreadychecklist.com/vendors/medusa/), [Payload](https://agentreadychecklist.com/vendors/payload/), [Vercel](https://agentreadychecklist.com/vendors/vercel/) Same type [Frameworks](https://agentreadychecklist.com/vendors/by-type/framework/), [all vendors](https://agentreadychecklist.com/vendors/) ## Sources - [nextjs.org](https://nextjs.org)read 2026-11-05 - [registry.npmjs.org/next](https://registry.npmjs.org/next)read 2026-11-05 - [nextjs.org/blog/next-16](https://nextjs.org/blog/next-16)read 2026-11-05 - [nextjs.org/docs/app/guides/mcp](https://nextjs.org/docs/app/guides/mcp)read 2026-11-05 - [nextjs.org/docs/app/getting-started/server-and-client-components](https://nextjs.org/docs/app/getting-started/server-and-client-components)read 2026-11-05 - [nextjs.org/docs/app/api-reference/functions/not-found](https://nextjs.org/docs/app/api-reference/functions/not-found)read 2026-11-05 - [nextjs.org/docs/app/api-reference/file-conventions/proxy](https://nextjs.org/docs/app/api-reference/file-conventions/proxy)read 2026-11-05 - [nextjs.org/docs/app/api-reference/file-conventions/metadata/robots](https://nextjs.org/docs/app/api-reference/file-conventions/metadata/robots)read 2026-11-05 - [nextjs.org/docs/llms.txt](https://nextjs.org/docs/llms.txt)read 2026-11-05 - [nextjs.org/docs/app/api-reference/file-conventions/metadata/sitemap](https://nextjs.org/docs/app/api-reference/file-conventions/metadata/sitemap)read 2026-11-05 - [nextjs.org/docs/app/api-reference/file-conventions/route](https://nextjs.org/docs/app/api-reference/file-conventions/route)read 2026-11-05 - [nextjs.org/docs/app/guides/json-ld](https://nextjs.org/docs/app/guides/json-ld)read 2026-11-05 - [nextjs.org/docs/app/api-reference/functions/generate-metadata](https://nextjs.org/docs/app/api-reference/functions/generate-metadata)read 2026-11-05 - [isitagentready.com](https://isitagentready.com/)read 2026-11-05 - [agentreadychecklist.com/data/](https://agentreadychecklist.com/data/)read 2026-11-04 Edition Data 2026-11-04 Reviewed 2026-11-05 Spec AgentReady v2.0, 273d2d7 Crawl 13,071 rows, 2026-11-04 Ora 132 checks, contract 1.38.0, 2026-11-05 Verify with Ora The scanner this site recommends for the whole checklist. 132 checks, a score out of 100, no account. `npx ax@0.10 audit --min-score ` [Why Ora, and its limits](https://agentreadychecklist.com/verify-with-ora/) Method - [How rows, commands and rates are made](https://agentreadychecklist.com/method/) - [How an Ora check is matched to a row](https://agentreadychecklist.com/checklist/ora-checks/) - [Pass rates by rank band](https://agentreadychecklist.com/data/by-rank/) Sources and read dates sit at the foot of the page.
