B12

B12 Website Generator MCP Server

B12's Model Context Protocol server, and the only machine-callable surface B12 publishes. It exposes a single tool, generate_website, which builds a website draft with AI from a business name, description, image keywords and subtitle, then returns a static preview image and a signup link to claim and edit the site. Two remote deployments run in parallel: mcp.b12.io/mcp serves Claude with an MCP-UI preview resource, and b12.io/mcp serves ChatGPT Apps. Both answer anonymously with no API key, token or OAuth challenge.
