Ask Claude to connect your own domain

One message to a Claude that has the Fine Structure connector builds this, publishes it, and returns a live link. You get your domain attached to the published app, the exact DNS records to add, and confirmation once the certificate is live.

The prompt

Paste this into Claude exactly as it is, or open it from the gallery, where the same prompt is available in eighteen languages and opens the Claude desktop app already typed.

Connect my own domain to my published Fine Structure app, tell me exactly which DNS records to add, and confirm when the certificate is live.

What happens after you send it

  1. Claude calls create_app and generates the pages, the database tables and the styling.
  2. It polls the build until it finishes, which usually takes a few minutes.
  3. It publishes the app and returns a public link that works for anyone you send it to.
  4. Anything you want changed is another sentence in the same conversation, and every change keeps a saved version you can roll back to.

Questions people ask

How long does the certificate take?

It issues automatically once the DNS records resolve, usually within minutes.

Do I lose the free address?

No, the Fine Structure subdomain keeps working alongside your domain.

Connecting takes about two minutes

  1. Open claude.ai and sign in. A free Claude account is enough; free accounts can add one custom connector.
  2. Go to Settings, then Connectors, choose Browse connectors, and search for Fine Structure. Click Connect.
  3. Sign in with a Fine Structure account (the free tier is enough, no credit card) and approve.
  4. Back in the chat, ask for what you want built. The result is published at a public link.

In Claude Code: claude mcp add --transport http finestructure https://finestructure.ai/api/mcp, then run /mcp to authenticate. The full guide covers the desktop app and every other client.

What it costs

A free Fine Structure account builds and publishes this at a free subdomain, with no credit card. A free Claude account can add one custom connector. Paid plans add your own domain and higher limits, detailed on the pricing page.

Where this is listed

Fine Structure is a Community connector in Anthropic's connector directory (listed, not verified or endorsed), and the same server is recorded in the official MCP registry as ai.finestructure/fine-structure, on Smithery and on Glama. The endpoint answers publicly at /api/mcp/manifest, so any claim on this page can be checked against the live tool list.
