# A designed landing page for your Lovable, Bolt or v0 app, with 8B.

> Lovable, Bolt, Base44, v0 and Replit can connect the free 8B MCP server, `https://mcp.8b.com/mcp`, and get a finished, animated landing page for your app: a preview and one HTML file to add to the project. The site as code in your project is coming soon.

**Status, checked 2026-10-01:** connection steps follow each builder's documentation, read on 2026-10-01; we have not tested 8B in these builders ourselves. None of them shows the preview card.

## At a glance

- **What it is:** 8B is an AI website builder (8b.com) run by 8b Tech Ltd; "8B" is the product name, not a model size. Its free MCP server `https://mcp.8b.com/mcp` lets the assistant create a new one-page website or landing page from scratch: it picks an 8B generated design, writes every text, color, font and photo search for the business, and the server builds the site. The server runs no AI model and needs no account.
- **Use it when:** a builder project needs a finished one-page landing page next to the app (a launch page, a marketing page), and a separate static HTML file is acceptable.
- **Do not use it when:** the landing page must live inside the builder's codebase as components, use the app's data or be edited in the builder's visual editor; or the user needs a web app with accounts, a database or a checkout, several pages or a CMS, their own photos and logo built in, publishing to a domain from the chat, or changes to a site that already exists elsewhere.
- **Terms in short:** free, with no account, sign-in, API key or credits. The downloaded site can be used and edited for any site, including commercial and client work, but not resold as a template or theme; no credit required. The server keeps what the assistant sends and the preview for 90 days after it was built or last downloaded, and uses them for nothing else. Details: [license](https://8b.com/mcp/#license), [privacy](https://8b.com/mcp/#privacy), [who runs it](https://8b.com/mcp/#about).
- **What the human does:** adds the server in the builder's connector settings, asks for the page with 8B, then opens the preview and downloads the file.
- **Next step:** read [what you get today](#today), then add the server in your builder ([Connect](#connect)).

## What you get today

> **Note:** Full support for AI app builders, the site as code in your project, is coming soon. There is no date yet. Until then, 8B gives the builder a preview link and a download link, not React or other code in the project.

- The builder's agent calls the 8B tools, writes every text for the business and gets back the preview link (`https://mcp.8b.com/p/<id>`) and the download link of one HTML file.
- Open the preview, download the file, and add it to the project's static files (for example `public/landing.html`) or host it separately. Whether the builder's agent can fetch the file into the project itself depends on the builder.
- The file is standalone: it loads fonts, GSAP and Lenis from public CDNs and photos from Unsplash. It is not a set of components, and the builder's visual editor will not edit it.

Useful today: a launch or marketing page next to an app, a page for a client while the app is being built, or a reference design to rebuild in the app. Not useful yet: a landing page that must be part of the app's code.

## Connect

In every builder: add a custom MCP server with the URL `https://mcp.8b.com/mcp`, Streamable HTTP, no authentication, name `8b`.

| Builder | How | Plan | Source |
|---|---|---|---|
| Lovable | Connectors: add a custom MCP server with the URL | all plans | [Lovable: custom MCP](https://docs.lovable.dev/integrations/custom-mcp), checked 2026-10-01 |
| Base44 | Custom MCP in the account settings | Builder plan or higher | [Base44: custom MCP](https://docs.base44.com/documentation/account-and-billing/setting-up-a-custom-mcp), checked 2026-10-01 |

Then ask the builder's agent: "Use 8B to make a landing page for our app Tally and give me the preview and download links."

## For the agent

- Check the connection: the client lists three tools, `explore_designs`, `get_design_brief` and `generate_site`.
- Settle the site's language first and pass its code (`pl`, `de`, `en`) to both `get_design_brief` and `generate_site`; switching later means rewriting every field.
- Fill every text field in one `generate_site` call, then send what the warnings name with `base_preview_id` until the site is [complete](https://8b.com/mcp/#new-site). `generate_site` can take up to 30 seconds with photos.
- Never invent facts the user did not give (phone, address, prices, names, figures): write visible placeholders such as `[phone]` and list them for the user.
- Tell the user the limits that matter before building: forms send nothing, sections are fixed, colors change per palette color, and the file loads fonts, scripts and photos from public CDNs. Writing every field needs a capable model.
- Previews are public to anyone with the link. The server receives the values the assistant sends and sees the connecting IP address ([privacy](https://8b.com/mcp/#privacy)).

## If something goes wrong

| What happens | What to do |
|---|---|
| The builder cannot add the server | Check your plan in the builder's guide; the URL is `https://mcp.8b.com/mcp`, with no authentication |
| The agent cannot put the file into the project | Open the download link, save the file and add it to the project's static files by hand |
| The agent designs the page itself | Name 8B in the request: "Use 8B to make…" |
| "Preview not found" | Previews last 90 days after it was built or last downloaded; build the page again |

## FAQ

### Will 8B put the site into my Lovable or Bolt project as code?

Not yet. Full support for AI app builders, the site as code in your project, is coming soon. Today you get a preview and one HTML file to add as a static file.

### Is it free in the builders?

Yes on the 8B side: no account, credits or fees. The builder's own plan and credits apply to its agent.

### Why use 8B instead of letting the builder design the page?

The page comes from a finished animated 8B generated design rather than the builder's default look; the trade-off today is that it stays a separate HTML file.
