Overview

Description from the maker (original English)

50 developer utility APIs as tools: SSL, DNS, WHOIS, email checks, HTML to PDF, sitemaps and more.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Chat & email
  • You need to fill in: APIXIES_API_KEY

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on your computer with your user’s permissions (files, network, apps).
  • You fill in yourself: APIXIES_API_KEY

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

  • npmNode.js installed (for the npx command)

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "apixies": {
      "command": "npx",
      "args": [
        "-y",
        "@apixies/mcp-server"
      ],
      "env": {
        "APIXIES_API_KEY": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add apixies --env APIXIES_API_KEY=your-value -- npx -y @apixies/mcp-server

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "apixies": {
      "command": "npx",
      "args": [
        "-y",
        "@apixies/mcp-server"
      ],
      "env": {
        "APIXIES_API_KEY": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "apixies": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@apixies/mcp-server"
      ],
      "env": {
        "APIXIES_API_KEY": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Common questions

Is Apixies Developer API Suite safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: APIXIES_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.4.2) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

Apixies MCP Server

Connect 52+ developer utility APIs to Claude, Cursor, and any MCP-compatible AI tool.

Check SSL certificates, look up DNS records, validate emails, generate QR codes, convert HTML to PDF, and more. All through natural language.

Quick Start

Add this to your MCP client config:

{

"mcpServers": { "apixies": { "command": "npx", "args": ["-y", "@apixies/mcp-server"], "env": { "APIXIES_API_KEY": "apx_your_key_here" } } } }

Get a free API key at apixies.io/register. The server needs one. Without it every tool call returns a MISSING_API_KEY error.

Setup by Client

Claude Desktop

One click: download apixies.mcpb and double-click it. Claude Desktop asks for your API key and you're done.

Or by hand:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json Windows: %APPDATA%\Claude\claude_desktop_config.json

{

"mcpServers": { "apixies": { "command": "npx", "args": ["-y", "@apixies/mcp-server"], "env": { "APIXIES_API_KEY": "apx_your_key_here" } } } }

Restart Claude Desktop after saving.

Claude Code

Add to your project's .mcp.json or global config:

{

"mcpServers": { "apixies": { "command": "npx", "args": ["-y", "@apixies/mcp-server"], "env": { "APIXIES_API_KEY": "apx_your_key_here" } } } }

Cursor

Add to .cursor/mcp.json in your project root:

{

"mcpServers": { "apixies": { "command": "npx", "args": ["-y", "@apixies/mcp-server"], "env": { "APIXIES_API_KEY": "apx_your_key_here" } } } }

VS Code

Add to .vscode/mcp.json:

{

"mcpServers": { "apixies": { "command": "npx", "args": ["-y", "@apixies/mcp-server"], "env": { "APIXIES_API_KEY": "apx_your_key_here" } } } }

Windsurf

Add to ~/.codeium/windsurf/mcp_config.json:

{

"mcpServers": { "apixies": { "command": "npx", "args": ["-y", "@apixies/mcp-server"], "env": { "APIXIES_API_KEY": "apx_your_key_here" } } } }

Example Conversations

SSL check:

You: Check if stripe.com has a valid SSL certificate

Claude uses check_ssl tool, then responds with issuer, expiry date, protocol version, and chain health.

DNS lookup:

You: What are the MX records for github.com?

Claude uses dns_lookup with type "MX" and returns the mail server records.

Multi-tool workflow:

You: Do a security audit on mysite.com. Check SSL, security headers, and email authentication.

Claude calls check_ssl, check_headers, and validate_email_auth in sequence, then gives you a combined report.

API Key

The server needs an API key. It's free: register at apixies.io/register, create a key in the dashboard, and you get 75 requests a day.

Set it with the APIXIES_API_KEY environment variable in your MCP client config. The Claude Desktop extension asks for it when you install.

Privacy Policy

The server runs on your machine and sends only the arguments of each tool call (a domain, a URL, some text) to the Apixies API at https://apixies.io, together with your API key. It doesn't read your files, your conversations or anything else on your computer, and it has no telemetry of its own.

Apixies logs API requests for up to 90 days to enforce quotas and debug problems. Payload fields such as text, HTML and email addresses are redacted from those logs. Nothing is sold or shared for advertising.

Full policy: apixies.io/privacy. Questions: hello@apixies.io.

Development

cd mcp-server

npm install npm run build npm run inspect # Opens MCP Inspector to test tools

For local development with auto-reload:

npm run dev

To run against a local Apixies instance, set APIXIES_BASE_URL (for example http://localhost:8000). It defaults to https://apixies.io.

Troubleshooting

Tools don't appear in Claude Desktop

  • Make sure you restarted Claude Desktop after editing the config
  • Check the config file path is correct for your OS
  • Verify Node.js 18+ is installed: node --version

"APIXIES_API_KEY not set" warning

  • The server starts, but every tool call fails with MISSING_API_KEY
  • Add your API key to the env config and restart the client

Rate limit errors

  • Free tier: 75 requests/day with an API key, 20 without
  • Errors include a DAILY_QUOTA_EXCEEDED code

Connection timeout

  • Some tools (screenshot, performance check) may take a few seconds
  • If consistently timing out, check your network connection
