API Freaks MCP Server

Why use API Freaks MCP?

Before you start

You'll need Node.js v20 or higher and an API Freaks API key.

To get a key:

1. Create a free account.
2. Open your dashboard and go to API Keys.
3. Copy your key.

You'll pass it to the server as the APIFREAKS_API_KEY environment variable, shown in each setup below. Full API reference: APIFreaks Docs.

Platform Integrations

The setup is the same idea everywhere: run the server with npx -y @apifreaks/mcp and pass your key as APIFREAKS_API_KEY. Pick your client below.

Claude Code

Add it from the terminal (recommended):

claude mcp add apifreaks -e APIFREAKS_API_KEY=your_apikey_here -- npx -y @apifreaks/mcp

Or edit the config file at ~/.claude/settings.json:

{
  "mcpServers": {
    "apifreaks": {
      "command": "npx",
      "args": [
        "-y",
        "@apifreaks/mcp"
      ],
      "env": {
        "APIFREAKS_API_KEY": "your_apikey_here"
      }
    }
  }
}

Claude Desktop

Edit claude_desktop_config.json:

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

{
  "mcpServers": {
    "apifreaks": {
      "command": "npx",
      "args": [
        "-y",
        "@apifreaks/mcp"
      ],
      "env": {
        "APIFREAKS_API_KEY": "your_apikey_here"
      }
    }
  }
}

Restart Claude Desktop after you save.

Codex CLI

codex mcp add apifreaks --env APIFREAKS_API_KEY=your_apikey_here -- npx -y @apifreaks/mcp

Start a new Codex session after you add the server.

Cursor

Create or edit .cursor/mcp.json in your project root, or ~/.cursor/mcp.json for a global setup:

{
  "mcpServers": {
    "apifreaks": {
      "command": "npx",
      "args": [
        "-y",
        "@apifreaks/mcp"
      ],
      "env": {
        "APIFREAKS_API_KEY": "your_apikey_here"
      }
    }
  }
}

You can also add it through the UI under Cursor Settings → MCP.

Windsurf

Edit ~/.codeium/windsurf/mcp_config.json:

{
  "mcpServers": {
    "apifreaks": {
      "command": "npx",
      "args": [
        "-y",
        "@apifreaks/mcp"
      ],
      "env": {
        "APIFREAKS_API_KEY": "your_apikey_here"
      }
    }
  }
}

Gemini CLI

Edit ~/.gemini/settings.json, or .gemini/settings.json in your project root for project-level config:

{
  "mcpServers": {
    "apifreaks": {
      "command": "npx",
      "args": [
        "-y",
        "@apifreaks/mcp"
      ],
      "env": {
        "APIFREAKS_API_KEY": "your_apikey_here"
      }
    }
  }
}

VS Code (GitHub Copilot / Continue)

Create .vscode/mcp.json in your workspace:

{
  "servers": {
    "apifreaks": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@apifreaks/mcp"
      ],
      "env": {
        "APIFREAKS_API_KEY": "your_apikey_here"
      }
    }
  }

Example prompts for API Freaks MCP

You don't call tools by name. Ask in plain language and your assistant picks the right one, runs it, and works the answer into its reply. Click the copy icon on any prompt block to paste it directly into your assistant:

WHOIS & Domain Ownership

Who owns the domain apple.com? Give me the full WHOIS record including registrar, creation date, and expiry date.

Now check if apple.com's WHOIS record has changed recently - pull the history for any nameserver or registrant updates.

Find other domains registered by the same organisation using a reverse WHOIS lookup by company name.

IP & ASN Intelligence

What organization owns the IP address 8.8.8.8? Give me the ASN, route prefix, and the city-level location.

Now look up that ASN - AS15169 - show me the organisation name, country, and all associated route prefixes.

What upstreams does AS15169 peer with? Check AS24940 and list its upstream ASN numbers.

Is the IP 1.1.1.1 anycast? Show me the announced route prefix and the ASN that originates it.

For IP 2.56.12.11, pull the abuse contact email, phone number, and the organisation responsible.

Check these IPs for VPN, proxy, Tor, bot, and spam indicators: 49.12.212.42, 2.56.12.11, 8.8.8.8

DNS Records & History

What are the MX, NS, and A records for github.com? Show me all of them organised by record type.

Has github.com changed its IP addresses in the last 2 years? Pull the DNS history and highlight any changes.

Which other domains or hostnames are currently pointing to the same IPs as github.com? Run a reverse DNS lookup.

Now check stripe.com's SPF, DKIM, and DMARC records - are they configured correctly for email deliverability?

Domain Availability & Discovery

Is mycompany.io available to register? If not, suggest 5 similar domain alternatives I could try.

Now check what known subdomains exist for tesla.com - I want to map their external attack surface.

Also find domains that are similar to "google" - possible typosquatting domains registered by third parties.

Email Validation

Is contact@example.com a valid, deliverable email address? Run SMTP verification and check if the mailbox actually exists.

Now verify these other addresses in bulk and tell me which are risky or invalid: admin@stripe.com, test@nonexistent12345.com, hello@apple.com

You can combine multiple tools in one request - ask it to check a domain's registration, DNS records, certificate, and hosting at once, and it pulls each piece before answering. For everything available, see Supported Tools.

Troubleshooting

Still stuck? Email support@apifreaks.com or open an issue on GitHub.
