Can Claude build me a website?

Yes. With the Fine Structure connector from Claude's directory, Claude builds the site, hosts it, publishes it at a public address on a free subdomain, and keeps editing it in later conversations. A custom domain with automatic TLS attaches on paid plans.

The difference from asking Claude for HTML is that nothing lands in your lap to deploy: hosting, database, authentication and TLS are part of the same account the connector works in. You ask, it goes live, and the next request edits the live thing.

What the connector actually does

Generates a complete application from a prompt: React pages, a managed database, authentication, styling.
Publishes to a live URL on a free subdomain, and connects a custom domain with automatic TLS on paid plans.
Edits existing apps: reads files, patches them, validates, republishes. Every change keeps a restorable saved version.
Creates database schemas and records, queries them back, and reports on them.
Reads traffic analytics and runtime errors for published apps, then fixes what it finds.
Creates standing AI agents that run on a schedule and can message their verified owner on WhatsApp and by email.
82 tools over the OAuth surface and 13 starter prompts, documented at finestructure.ai/api/mcp/docs.

Connecting takes about two minutes

Open claude.ai and sign in. A free Claude account is enough; free accounts can add one custom connector.
Go to Settings, then Connectors, choose Browse connectors, and search for Fine Structure. Click Connect.
Sign in with a Fine Structure account (the free tier is enough, no credit card) and approve.
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.

Questions people ask

Where is the website hosted?

On Fine Structure's infrastructure, at yourname.finestructure.ai for free, or on your own domain with automatically issued certificates on paid plans.

Can I edit it later without Claude?

Yes. The same app opens in the Fine Structure Studio, a full visual editor, and every Claude edit keeps a saved version you can restore from either surface.

Do I need an API key?

No. The connector uses OAuth: you sign in on a Fine Structure page and approve. No key, no client ID, no secret to paste anywhere.

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.
