Overview

AI-generated overview

Local MCP server for nintact contact forms: an assistant can build forms, read submissions, and approve AI-drafted replies from the editor.

What you can do
Diagnose whether a domain can receive mail by reading public DNS records and returning a verdict with a next step. Design, create, list, get, update, duplicate and delete contact forms, and set or remove a form logo. Read the inbox, open messages and change their status. Regenerate, edit and approve AI-drafted replies. Manage the knowledge used to ground drafts, including scanning a site for it. Manage workspace settings, usage, inbound addresses and a custom sending domain.
When to use it
Useful when a site built with an AI assistant needs a working contact form without DNS, SMTP or mail-provider setup, and you want the assistant to create the form, triage incoming messages and prepare replies. Also handy for checking, before signup, whether a domain's mail will be delivered.
Requirements
Runs locally over stdio via npx, so Node.js is needed. Most tools need a nintact account and an API key, supplied as NINTACT_API_KEY or created with the login command, which stores it in a local config file. The deliverability check works without an account. Desktop MCP clients only; ChatGPT connectors cannot run a local server.
Before you install
Approving a draft sends a real email, so confirm with the person first. The API key is a live credential; the login command stores it locally, while passing it on the command line can leave it in shell history and client config. Tools can create, update and delete forms, messages, knowledge entries, inbound addresses and sending domains. Setting notification addresses sends confirmation links and holds notifications until they are confirmed. AI processing can be switched off per form.

Installation

In SourceWeft

  1. Open nintact in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

README

nintact-mcp

MCP server for nintact — a contact form you paste in one line, an AI that sorts what comes in and drafts the reply, and delivery that needs no DNS work.

Build the form, read the inbox, and approve replies without leaving your editor.

Why this exists

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 the person who built the site finds out weeks later, from the customer who never got an answer.

nintact sends over an already-authenticated domain with Reply-To pointing at your own address, so replies reach you without you touching DNS, SMTP, or a mail provider.

Install

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

login writes the key to ~/.nintact/config.json (0600). Passing it on the command line also works and is what CI wants:

bash
claude mcp add nintact --env NINTACT_API_KEY=nk_live_... -- npx -y nintact-mcp

Prefer login on a person's own machine — a key typed into a command ends up in shell history and in the client's config file in plaintext.

No claude on PATH?

The desktop app alone does not install the CLI. Add this at the top level of ~/.claude.json. A session that is already open will not pick it up; open a new one.

json
{  "mcpServers": {    "nintact": {      "type": "stdio",      "command": "npx",      "args": ["-y", "nintact-mcp"]    }  }}

Any MCP client works — Cursor, Codex CLI, Claude Desktop. ChatGPT itself cannot: its connectors only accept a server published over HTTPS, not one run locally.

Works without an account

check_deliverability needs no API key. It reads public DNS and tells you whether a domain can actually get mail delivered — which is usually the question, before anyone has signed up for anything.

check_deliverability("example.com")→ { spf: "missing", dmarc: "missing", verdict: "will_be_rejected",    next_step: "..." }

Tools

32 tools covering the same surface as the REST API. No screen-only features.

Every error carries a next_step field describing how to recover, so an agent can fix its own mistake instead of giving up on the tool.

Things worth knowing before you point this at someone's account

  • approve_draft sends a real email. Confirm with the person first. nintact never sends without an explicit approval, and neither should you.
  • Call get_organization (or the API's GET /me) first. It returns the workspace name and how many forms already exist. If that count is not zero, reuse a form instead of adding one — inquiries split across two forms land in two places, and the owner only watches one.
  • Notifications are held until the address confirms. Setting notify_emails emails a confirmation link to each address. Until someone opens it, submissions are stored and visible in the dashboard but no notification goes out. Tell the owner to check their mail.
  • AI can be switched off per form. update_form with mode: "relay" forwards everything untouched — no classification, no draft, nothing sent to a model.

Verifying an install without creating a real inquiry

bash
curl -X POST 'https://nintact.com/api/f/YOUR_FORM_ID?dry_run=1' \  -H 'Content-Type: application/json' \  -d '{"name":"Test","email":"[email protected]","message":"checking the install"}'

Everything is checked as in a real submission, then nothing is stored and nobody is notified. 200 with {"data":{"ok":true,...}} means the install is correct. Use this instead of sending a real submission to someone else's inbox.
