## Description

Securely connect your AI agents and chatbots (Claude, ChatGPT, Cursor, etc) with Ip2whois MCP or direct API to look up domain WHOIS data, retrieve registrant and admin contacts, check domain age and expiration, and analyze nameserver information through natural language.

## Summary

Ip2whois is a WHOIS lookup API delivering detailed domain registration info and metadata. Get instant access to creation dates, registrant contacts, and nameservers for any domain.

## Categories

- data & analytics

## Toolkit Details

- Tools: 2

## Images

- Logo: https://www.ip2whois.com/images/logo.png

## Authentication

- **Api Key**
  - Type: `api_key`
  - Description: Api Key authentication for Ip2Whois.
  - Setup:
    - Configure Api Key credentials for Ip2Whois.
    - Use the credentials when creating an auth config in Composio.

## Suggested Prompts

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `IP2WHOIS_DOMAIN_LOOKUP` | IP2WHOIS Domain Lookup | Retrieves WHOIS registration data for any domain. Returns registrar info, registration/expiration dates, domain age, nameservers, and contact details (registrant, admin, tech, billing). Use to investigate domain ownership, check availability, verify legitimacy, or research competitors. Note: Some data may be redacted due to WHOIS privacy protection. |

## Installation and MCP Setup

### Path 1: SDK Installation

#### Path 1, Step 1: Install Composio

Install the Composio SDK
```python
pip install composio_openai
```

```typescript
npm install @composio/openai
```

#### Path 1, Step 2: Initialize Composio and Create Tool Router Session

Import and initialize Composio client, then create a Tool Router session
```python
from openai import OpenAI
from composio import Composio
from composio_openai import OpenAIResponsesProvider

composio = Composio(provider=OpenAIResponsesProvider())
openai = OpenAI()
session = composio.create(user_id='your-user-id')
```

```typescript
import OpenAI from 'openai';
import { Composio } from '@composio/core';
import { OpenAIResponsesProvider } from '@composio/openai';

const composio = new Composio({
  provider: new OpenAIResponsesProvider(),
});
const openai = new OpenAI({});
const session = await composio.create('your-user-id');
```

#### Path 1, Step 3: Execute Ip2whois Tools via Tool Router with Your Agent

Get tools from Tool Router session and execute Ip2whois actions with your Agent
```python
tools = session.tools
response = openai.responses.create(
  model='gpt-4.1',
  tools=tools,
  input=[{
    'role': 'user',
    'content': 'Get WHOIS details for example.com'
  }]
)
result = composio.provider.handle_tool_calls(
  response=response,
  user_id='your-user-id'
)
print(result)
```

```typescript
const tools = session.tools;
const response = await openai.responses.create({
  model: 'gpt-4.1',
  tools: tools,
  input: [{
    role: 'user',
    content: 'Get WHOIS details for example.com'
  }],
});
const result = await composio.provider.handleToolCalls(
  'your-user-id',
  response.output
);
console.log(result);
```

### Path 2: MCP Server Setup

#### Path 2, Step 1: Install Composio

Install the Composio SDK and Claude Agent SDK
```python
pip install composio claude-agent-sdk
```

```typescript
npm install @composio/core ai @ai-sdk/openai @ai-sdk/mcp
```

#### Path 2, Step 2: Create Tool Router Session

Initialize the Composio client and create a Tool Router session
```python
from composio import Composio
from claude_agent_sdk import ClaudeSDKClient, ClaudeAgentOptions

composio = Composio(api_key='your-composio-api-key')
session = composio.create(user_id='your-user-id')
url = session.mcp.url
```

```typescript
import { Composio } from '@composio/core';

const composio = new Composio({ apiKey: 'your-api-key' });

console.log("Creating Tool Router session...");
const { mcp } = await composio.create('your-user-id');
console.log(`Tool Router session created: ${mcp.url}`);
```

#### Path 2, Step 3: Connect to AI Agent

Use the MCP server with your AI agent
```python
import asyncio

options = ClaudeAgentOptions(
    permission_mode='bypassPermissions',
    mcp_servers={
        'tool_router': {
            'type': 'http',
            'url': url,
            'headers': {
                'x-api-key': 'your-composio-api-key'
            }
        }
    },
    system_prompt='You are a helpful assistant with access to Ip2whois tools.',
    max_turns=10
)

async def main():
    async with ClaudeSDKClient(options=options) as client:
        await client.query('Get WHOIS info for example.com')
        async for message in client.receive_response():
            if hasattr(message, 'content'):
                for block in message.content:
                    if hasattr(block, 'text'):
                        print(block.text)

asyncio.run(main())
```

```typescript
import { openai } from '@ai-sdk/openai';
import { experimental_createMCPClient as createMCPClient } from '@ai-sdk/mcp';
import { generateText, stepCountIs } from 'ai';

const client = await createMCPClient({
  transport: {
    type: 'http',
    url: mcp.url,
    headers: { 'x-api-key': 'your-composio-api-key' }
  }
});

const tools = await client.tools();

const { text } = await generateText({
  model: openai('gpt-4o'),
  tools,
  messages: [{ role: 'user', content: 'Get WHOIS info for example.com' }],
  stopWhen: stepCountIs(5)
});

console.log(`Agent: ${text}`);
```
