Apixies MCP Server

Connect 39+ 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. Works without a key too (sandbox mode, 20 requests/day).

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 works in two modes:

• Without a key (sandbox): 20 requests per day. Good for trying it out.
• With a free key: 75 requests per day. Register at apixies.io/register.

Set your key via the APIXIES_API_KEY environment variable in your MCP client config.

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

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 still works in sandbox mode (20 req/day)
• To remove the warning, add your API key to the env config

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
