Zactonz tools (18, 2 write)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • capture_screenshot

    Loads a public web page in a headless browser and captures it as a JPEG, PNG or WebP image, or as a PDF. Returns a link to the file, and the image itself when it is small enough to look at directly. Suited to checking how a page renders or keeping a visual record of it.

  • check_email_domainwrite action

    Audits how a domain is configured for email: MX, SPF, DKIM, DMARC, MTA-STS, TLS-RPT and BIMI records, whether it is a disposable or free mail provider, a score out of 100 and a list of findings.

  • convert_html_to_markdown

    Converts HTML you already hold to Markdown. Nothing is fetched.

  • convert_image

    Converts an image at a public URL to WebP, AVIF, JPEG, PNG or GIF, optionally resizing, cropping, rotating, flipping, blurring, sharpening or removing colour. Returns a link valid for 24 hours with the source and output details, and the image itself when it is small enough.

  • generate_barcode

    Renders a barcode: Code 128, Code 39, Code 93, EAN-13, EAN-8, UPC-A, UPC-E, ITF-14 or Codabar. Returns a link valid for 24 hours, the dimensions and the image itself.

  • generate_qr_code

    Encodes text or a URL as a QR code. Returns a link to the image and the image itself. With the text format it returns the code as rows of 0 and 1 instead.

  • generate_social_imagewrite action

    Creates an Open Graph image, the card shown when a link is shared, from a title and an optional subtitle, site label and logo. Returns a link valid for seven days and the image itself.

  • get_drive_download_link

    Converts a Google Drive share link into a URL that downloads the file directly.

  • inspect_image

    Reports the width, height, format, file size, orientation, transparency and dominant colours of an image at a public URL.

  • inspect_ssl_certificate

    Connects to a host and reports its TLS certificate: issuer, subject, validity dates, days remaining, whether the chain is trusted and the name matches, and the protocol and cipher in use.

  • lookup_dns

    Returns the DNS records of a host or domain (A, AAAA, MX, TXT, NS, CNAME, SOA, CAA, SRV) and its DNSSEC status.

  • lookup_whois

    Returns the registration record of a domain from RDAP or WHOIS: registrar, creation, update and expiry dates, status codes, nameservers and abuse contact.

  • preview_link

    Reads the metadata of a public URL: title, description, preview image, favicon, site name, author, publication date, language and feeds. A quick way to learn what a link points to without reading the page.

  • read_qr_code

    Decodes the QR code in an image and returns the text it holds.

  • read_webpage

    Fetches a public web page and returns its main content as Markdown, without navigation, adverts or scripts. For pages that build their content with JavaScript, set render to true.

  • render_html

    Renders an HTML document you provide as a JPEG, PNG or WebP image, or as a PDF: an invoice, a report, a certificate. Returns a link to the file, and the image itself when it is small enough. Images, fonts and stylesheets referenced by the HTML must use absolute URLs.

  • translate_text

    Translates text from one language to another. 46 languages are supported.

  • verify_emails

    Checks whether email addresses can receive mail by asking the receiving mail server, without sending a message. Returns valid or invalid for each address. Can take up to a minute.

Install Zactonz in Claude Code, Cursor or VS Code

Runs npx -y @zactonz/mcp on your machine. Read the scan report first; the gateway never runs local packages.

claude mcp add zactonz-mcp -- npx -y @zactonz/mcp
Add to Cursor

What the publisher says

From the Zactonz repository's README, as published. We do not edit it. Read it on GitHub

Zactonz MCP server

A Model Context Protocol server for the Zactonz APIs. It lets an AI assistant capture a screenshot of a web page, read a page as Markdown, preview a link, look up DNS, SSL and WHOIS records, check a domain's email setup, verify addresses, generate QR codes, barcodes and social card images, convert images and translate text.

It runs on your machine over stdio and needs Node.js 18 or newer.

Install

There is nothing to install ahead of time. The client configurations below run npx -y @zactonz/mcp, which fetches the package on first use and keeps it cached. You need Node.js 18 or newer.

Skip to Setup unless you want to run it from a checkout.

From source

Useful for pinning a particular commit, working on the server, or running without a registry. Needs Node.js 18 or newer and git.

git clone https://github.com/zactonz/zactonz-mcp.git
cd zactonz-mcp
npm ci --omit=dev

That is the whole install: two runtime dependencies, no build step. Check it starts — it will wait for input, so press Ctrl+C to leave:

node bin/zactonz-mcp.js

Then point your client at the absolute path, in place of the npx form used below:

{
  "mcpServers": {
    "zactonz": {
      "command": "node",
      "args": ["/absolute/path/to/zactonz-mcp/bin/zactonz-mcp.js"],
      "env": {
        "ZACTONZ_API_KEYS": "zk_screen_…,zk_markdown_…"
      }
    }
  }
}

Use the real absolute path — ~ and relative paths are not expanded by most clients. On Windows, write it with forward slashes or escaped backslashes, for example C:/Users/you/zactonz-mcp/bin/zactonz-mcp.js.

For Claude Code:

claude mcp add zactonz --env ZACTONZ_API_KEYS="zk_screen_…" -- node /absolute/path/to/zactonz-mcp/bin/zactonz-mcp.js

If you would rather have zactonz-mcp on your PATH, run npm link in the clone, then use "command": "zactonz-mcp" with no args.

To update later: git pull && npm ci --omit=dev.

Setup

  1. Create a key for each product you want to use in the API console. There is a free plan.
  2. Add the server to your MCP client, with the keys in ZACTONZAPIKEYS separated by commas.

If you installed from source instead, substitute the "command" and "args" shown there for the npx form used below.

Clients that read an mcpServers block, such as Claude Desktop, Cursor and Windsurf:

{
  "mcpServers": {
    "zactonz": {
      "command": "npx",
      "args": ["-y", "@zactonz/mcp"],
      "env": {
        "ZACTONZ_API_KEYS": "zk_screen_…,zk_markdown_…,zk_domain_…"
      }
    }
  }
}

VS Code (.vscode/mcp.json):

{
  "servers": {
    "zactonz": {
      "command": "npx",
      "args": ["-y", "@zactonz/mcp"],
      "env": { "ZACTONZ_API_KEYS": "zk_screen_…,zk_markdown_…" }
    }
  }
}

Claude Code:

claude mcp add zactonz --env ZACTONZ_API_KEYS="zk_screen_…,zk_markdown_…" -- npx -y @zactonz/mcp

On Windows, if the client cannot start npx directly, use "command": "cmd" with "args": ["/c", "npx", "-y", "@zactonz/mcp"].

Keys

A Zactonz key works for one product, and the product is part of the key: zkscreen… is a screenshot key, zkmarkdown… a Markdown key. Put every key you have in ZACTONZAPIKEYS. The server uses the right one for each call and offers the assistant only the tools those keys can call.

Keys stay in the server process. They are sent to api.zactonz.com in the Authorization header and nowhere else, and they are never included in anything returned to the assistant.

Tools

Shortened. The full README is on GitHub.
