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
