Claude Website Generator by B12 connectorWhat Claude can build for you with B12.
The Claude Website Generator by B12 connector exposes 1 tool, and it writes. 0 reading tools, 0 undocumented ones. It drafts a site hosted by B12 from a project name and a short description, then hands you a preview and a link. Here is how it works and where it stops.

What a chat-built B12 website gives you, and what it does not
You give Claude two things, the name of your project and a sentence or two on what the site is for, and B12 produces a first version of the website. Claude shows you a static preview image in the conversation along with a link. That link is where the real work continues: on B12, outside the chat, you claim the site, adjust it and publish it.
A draft to react to. You give a project name and its goals, and generate_website returns a preview plus a link to the generated site, so there is something concrete to look at instead of a blank page.
Two directions, side by side. B12 states that calling the tool again creates a separate, additional website. Ask twice with two different descriptions and you get two distinct drafts to compare, each with its own link.
A head start without a B12 login. According to B12's help center, you can connect and generate a site without an existing B12 account. The account question comes later, when you open the link to claim the site.
What it will not do: change a site after the fact. The tool only creates. B12 says its websites can only be edited online with the b12.io software, so every tweak, page or wording change happens there, not in Claude. Nothing runs on its own either: Claude calls the tool while it answers you, never on a schedule. For recurring, unattended jobs, look at the automation platforms on the Integrations hub; other connectors are listed on the Claude integrations page.
Five terms before you connect B12
The Claude vocabulary used on this page, in one minute.
- Connector
- The link you set up once between Claude and an outside service, here B12's site builder, so Claude can call on it mid-reply.
- Tool
- One named thing a connector lets Claude do. This one has a single tool, generate_website, which Claude calls on its own.
- Authorization
- The sign-in screen of a service, where you hand Claude the access it uses afterwards. Granted once per person, and revocable.
- Approval
- The confirmation Claude waits for before an action that changes something on your behalf, shown in the chat when it matters.
- MCP
- The open standard connectors run on, which lets an assistant like Claude exchange requests with an outside service such as B12.
Connect Website Generator by B12 in three steps
- 01
Find the connector
Open Claude's settings, go to Customize then Connectors, and search for Website Generator by B12. If your Claude account belongs to a Team or Enterprise organization, an Owner or Primary Owner has to enable the connector there first.
- 02
Add it to Claude
Click Connect on its row. B12 documents no sign-in step of its own for generating a site: its help center says you can generate one without an existing B12 account. If a screen does ask for access, read it before you accept.
- 03
Switch it on in the chat
B12 asks you to check that the connector is toggled on for the conversation you are in, not only added to your account. If it misbehaves later, use Disconnect and connect it again.
The single Website Generator by B12 tool
Website Generator by B12 gives Claude 1 tool: 0 that read your account, 1 that change something in it.
A single tool, on the writing side: every run creates a fresh site. B12 describes it in the tool list its own server shares, and Claude displays its name unchanged.

What Claude creates (1)
1 toolgenerate_website builds a new B12 site on each call. B12 documents no confirmation of its own for it, so the approval section further down is what governs it.
generate_website
Approval: see the ruleTurns a project name and a few words on the site's purpose into a website, then returns a static preview image plus a link to claim and edit the site outside the conversation. B12 hosts the result, and each new call yields a separate, additional site.
What Claude asks before it generates a site
Unless told otherwise, Claude pauses for your OK every time it is about to act on an account for you, and that request shows up right in the chat.
Inside a Team or Enterprise organization, it is the owners who choose whether people may skip the repeated prompt for some actions. Owners can likewise narrow this connector for every member at once, and that setting cannot be bypassed from a personal account. Whatever happens, Claude stays inside the reach of whoever connected it. On B12's side, its help center says B12 itself takes care of creating and hosting the site once the request arrives.
Which Claude plans include it
Across the official directory, 819 sheets and not one lists plan availability. For this connector as for the rest, no source states it: the catalogue simply leaves that hole.
The rule Anthropic does publish is general. Remote connectors can be used by anyone on Claude, Cowork, Claude Desktop and the mobile apps. Team and Enterprise organizations add one step: an Owner or Primary Owner turns the connector on, and only then can members link it. To see where this one stands for you, open its sheet in the official directory. Also note that B12 is the only party documenting it.
Where Website Generator by B12 stops
This connector automates nothing. The tool only runs inside one of Claude's replies, so no site gets generated in the background or on a timer.
Treat the tool list as what was observed, not as a ceiling: administrators can enable actions that never appear on a public sheet. A verification badge does not mean a security review took place, and Anthropic states on each sheet that publishers choose their own tools and that it does not vouch for how they behave. Plug in only connectors whose publisher you trust, which here means B12 itself. Claude's help center has no article on this connector.
