Can Claude build and publish a landing page?

Yes, in one message: "Build a landing page for my business, add a lead form, publish it and give me the link." With Fine Structure connected, the page goes live on a free subdomain, the form writes into a real database table, and later messages change copy, design or structure.

Because the leads land in the app database, the follow-up is one more sentence: an agent that checks for new leads every morning and reports to you on WhatsApp. The landing page stops being a brochure and starts being a system.

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

Can I use my own domain?

Yes, on paid plans: add the domain in the chat or the Studio, set the DNS records shown, and TLS certificates issue automatically. The free subdomain link works from the first minute either way.

Where do the form submissions go?

Into the app's managed database, where Claude can query them, report on them, or wire an agent to follow up.

Does this work on a free Claude plan?

Yes. Anthropic documents custom remote MCP connectors on Free, Pro, Max, Team and Enterprise, with free accounts limited to one custom connector. A free Fine Structure account is enough on the other side, and no credit card is required.

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.
