claude mcp add nintact -e 'NINTACT_API_KEY=<your nintact_api_key>' -- npx -y nintact-mcp@0.5.1
JSON configuration (Claude Desktop, Cursor, VS Code)

            "command": "npx",
            "args": [
                "-y",
                "nintact-mcp@0.5.1"
            ],
            "env": {
                "NINTACT_API_KEY": "<your nintact_api_key>"

nintact — MCP server and JavaScript client

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.

PackageWhat it is
nintact-mcpMCP server — 32 tools. Build forms, read the inbox, approve replies from your editor.
nintactJavaScript client, React component, and CLI.

The problem this exists for

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.

Quick start

npx nintact-mcp login                          # 6-digit code by email; the key is stored, not pasted
claude mcp add nintact -- npx -y nintact-mcp

Then ask your assistant to build the form.

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