Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@nintact-mcp Create a contact form and list my unapproved draft replies"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
A contact form you paste in one line. An AI that sorts what comes in and drafts the reply. Delivery that needs no DNS work.
This repository holds the two published packages. The hosted service lives at nintact.com.
Package | What it is |
MCP server — 32 tools. Build forms, read the inbox, approve replies from your editor. | |
JavaScript client, React component, and CLI. |
A site built with an AI assistant usually works until the contact form. Then the mail silently stops. Gmail and Yahoo! reject mail from a domain with no SPF/DKIM, and whoever built the site finds out weeks later — from the customer who never got an answer.
The usual fixes all end at the same wall: an SMTP plugin still needs a domain you have authenticated, and authenticating a domain means DNS records the person often cannot edit.
nintact sends over an already-authenticated domain, with Reply-To pointing at your own address.
Replies reach you without touching DNS, SMTP, or a mail provider.

No account yet? check_deliverability works without a key — it reads public DNS and tells you
whether a domain can actually get mail delivered.
