## Description

Securely connect your AI agents and chatbots (Claude, ChatGPT, Cursor, etc) with Crawlbase MCP or direct API to crawl web pages, manage crawler queues, retrieve stored crawl results, and monitor account usage through natural language.

## Summary

Crawlbase is a web crawling API platform for fetching pages, managing crawler queues, storing crawl results, and tracking usage.
It helps developers collect web data at scale without building and maintaining crawler infrastructure.

## Categories

- data & analytics

## Toolkit Details

- Tools: 8

## Images

- Logo: https://logos.composio.dev/api/crawlbase

## Authentication

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

## Suggested Prompts

- Crawl product pages for pricing changes
- Extract headlines from competitor blogs
- Check crawl queue status today

## Supported Tools

## 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 Crawlbase Tools via Tool Router with Your Agent

Get tools from Tool Router session and execute Crawlbase actions with your Agent
```python
tools = session.tools
response = openai.responses.create(
  model='gpt-4.1',
  tools=tools,
  input=[{
    'role': 'user',
    'content': 'Crawl https://example.com and return the page title and main text'
  }]
)
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: 'Crawl https://example.com and return the page title and main text'
  }],
});
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 for Python or TypeScript
```python
pip install composio claude-agent-sdk
```

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

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

Import and initialize the Composio client, then create a Tool Router session for Crawlbase
```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' });
const session = await composio.create('your-user-id');
console.log(`Tool Router session created: ${session.mcp.url}`);
```

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

Use the MCP server with your AI agent (Anthropic Claude or Mastra)
```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 Crawlbase tools.',
    max_turns=10
)

async def main():
    async with ClaudeSDKClient(options=options) as client:
        await client.query('Crawl https://example.com and return the page title and main text')
        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 } from 'ai';

const client = await createMCPClient({
  transport: {
    type: 'http',
    url: session.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: 'Crawl https://example.com and return the page title and main text'
  }],
  maxSteps: 5,
});

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

## Why Use Composio?

### 1. AI Native Crawlbase Integration

- Supports both Crawlbase MCP and direct API based integrations
- Structured, LLM-friendly schemas for reliable crawl requests and queue actions
- Rich coverage for crawling pages, checking queues, reading stored results, and monitoring usage

### 2. Managed Auth

- Securely store Crawlbase API keys without hard-coding them in your agent code
- Central place to manage, scope, and revoke Crawlbase access
- Per user and per environment credentials, so staging and production stay cleanly separated

### 3. Agent Optimized Design

- Crawlbase tools are shaped so language models can pick the right crawl, queue, or result action
- Tools are tuned using real error and success rates to improve reliability over time
- Execution logs show what ran, when it ran, and which user triggered the crawl

### 4. Enterprise Grade Security

- Fine-grained RBAC so you control which agents and users can access Crawlbase
- Scoped, least privilege access for crawl requests, stored results, and usage data
- Full audit trail of agent actions to support review and compliance
