Build a website or web app in minutes! Generate, design, write code, and create copy for your website.
Visual Studio Code runs MCP servers for Copilot Chat in agent mode, so the model can use external tools while it works on your code.
This guide connects B12 MCP to VS Code through MewCP, so VS Code can use B12 MCP's 1 tool, like generate_website.
B12 MCP needs no credentials, but every call still runs through MewCP: scoped, checked and logged like any other.
Scope access to the exact B12 MCP tools and accounts you allow, work and personal side by side. Anything outside that scope is refused at call time, even when the model asks for it.

Other clients
B12 MCP works the same way in every client below. Pick yours for its own guide.
Free to start.
Each call is logged: what ran, on which account, and whether it worked. Failures come back structured, so the agent knows whether to retry instead of guessing.
Every app sits behind one secure MCP URL, and there is no server for you to deploy or keep running. Add an integration in the dashboard and it is live on the next call, with no config to change and no new credentials to wire up. Tools load only when a task needs them, so your agent stays fast and focused however many apps you connect.
A browser window opens the first time the client connects. Sign in and approve access. No API key needed.
Start a new chat and ask: "List the tools you can use from MewCP." You should see your connected apps.
Generate a website with AI. Use the project name and description arguments to provide guidance on the purpose of the website. The description argument may include high-level guidance on site structure or content to include, but not verbatim site copy. Absolutely NEVER invent a name or description, even as an example, and ALWAYS make sure you request the business name and description from the user before calling the tool and creating a website. Once you have called this tool, the response will contain a signup nonce (which you should ignore) and a message explaining that a website preview image has been shown to the user above the message. The message also contains a link to claim their website on a website editor outside of ChatGPT (websites are hosted by B12 and can only be edited online using the b12.io software suite). To avoid misleading the user, remember that the preview image they see above your response message is completely static. Users cannot add content or sections to the site in the preview panel. If a user asks to edit a site they created, you can send them to b12.io/dashboard to edit their site in the B12 editor, or instruct them to click the ‘sign up to see your website’ button in the static preview. If the user wants a completely new separate website (perhaps related to previous sites they have created), you can call the tool again to generate a new website preview image (static) and signup link.
