Summary

Gives Claude and other AI assistants the ability to create, read, and update link-in-bio sites at yourhandle.unu.lu through a streamable HTTP MCP server. Exposes operations to check handle availability, publish sites with name/bio/links, swap between 17 themes (minimal, gradient, brutalist, glass), and modify content on the fly. Sites go live instantly and expire after an hour unless claimed with email. No auth required. If you're building agent workflows that need to spin up simple landing pages or let users claim web presence conversationally, this handles the entire create and publish cycle without leaving the chat. Also available as a REST API if you want direct integration outside MCP.

MCP Badge

AI agent website builder, starting with link-in-bio sites. Create and publish via MCP server or REST API.

v1.0 — Stable API.

What is unulu?

unulu is a website builder designed for AI agents. You describe a site in conversation with an AI assistant — Claude, ChatGPT, Gemini, Cursor, or any MCP-compatible tool — and it builds and publishes the site instantly.

Starting with link-in-bio sites: a single page with your name, bio, and links, live at yourhandle.unu.lu. No signup, no templates, no manual work.

What AI agents can do

  • Create a link-in-bio site with a name, bio, links, and theme
  • Read the current state of any site
  • Update content — display name, bio, links, theme, link badges
  • Check handle availability before claiming
  • 17 built-in themes including minimal, gradient, brutalist, glass, and more

Sites are published instantly and expire after 1 hour unless claimed with an email address.

Quick start (MCP)

Add unulu to your MCP client config:

{
  "mcpServers": {
    "unulu": {
      "type": "streamable-http",
      "url": "https://mcp.unulu.ai"
    }
  }
}

No authentication required. Then ask your AI agent: "Build a link-in-bio site for me on unulu."

REST API

Base URL: https://api.unulu.ai

MethodPathDescription
POST/api/sitesCreate a link-in-bio site
GET/api/sites/{site_id}Get site state
PATCH/api/sites/{site_id}Update a site
GET/api/claims/check-handleCheck handle availability

No authentication required. Rate limited. Full spec: openapi.json
