## Introduction

This guide walks you through connecting Rocket reach to the Claude Agent SDK using the Composio tool router. By the end, you'll have a working Rocket reach agent that can find verified email for linkedin profile, get direct dial number for company executive, lookup job title for specific contact through natural language commands.
This guide will help you understand how to give your Claude Agent SDK agent real control over a Rocket reach account through Composio's Rocket reach MCP server.
Before we dive in, let's take a quick look at the key ideas and tools involved.

## TL;DR

Here's what you'll learn:
- Get and set up your Claude/Anthropic and Composio API keys
- Install the necessary dependencies
- Initialize Composio and create a Tool Router session for Rocket reach
- Configure an AI agent that can use Rocket reach as a tool
- Run a live chat session where you can ask the agent to perform Rocket reach operations

## What is Claude Agent SDK?

The Claude Agent SDK is Anthropic's official framework for building AI agents powered by Claude. It provides a streamlined interface for creating agents with MCP tool support and conversation management.
Key features include:
- Native MCP Support: Built-in support for Model Context Protocol servers
- Permission Modes: Control tool execution permissions
- Streaming Responses: Real-time response streaming for interactive applications
- Context Manager: Clean async context management for sessions

## What is the Rocket reach MCP server, and what's possible with it?

The Rocket reach MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your RocketReach account. It provides structured and secure access to professional contact information, so your agent can perform actions like finding verified emails, enriching lead profiles, searching for company details, and managing outreach research—all automatically on your behalf.
- Find verified contact details: Instantly retrieve accurate email addresses, phone numbers, and social profiles for prospects or candidates from the RocketReach database.
- Enrich and update lead profiles: Ask your agent to gather and supplement missing details about leads, including job titles, current companies, and social links.
- Company lookup and research: Have your agent pull company background, industry, size, and key personnel information to inform outreach and targeting strategies.
- List building and segmentation: Let your agent assemble lists of contacts based on filters like company, role, location, or industry, so you can streamline your outreach campaigns.
- Contact verification and scoring: Direct your agent to check the deliverability and accuracy of contact details, helping you prioritize the best leads or candidates.

## Creating MCP Server - Stand-alone vs Composio SDK

The Rocket reach MCP server is an implementation of the Model Context Protocol that connects your AI agent to Rocket reach. It provides structured and secure access so your agent can perform Rocket reach operations on your behalf through a secure, permission-based interface.
With Composio's managed implementation, you don't have to create your own developer app. For production, if you're building an end product, we recommend using your own credentials. The managed server helps you prototype fast and go from 0-1 faster.

## Step-by-step Guide

### 1. Prerequisites

Before starting, make sure you have:
- Composio API Key and Claude/Anthropic API Key
- Primary know-how of Claude Agents SDK
- A Rocket reach account
- Some knowledge of Python

### 1. Getting API Keys for Claude/Anthropic and Composio

Claude/Anthropic API Key
- Go to the [Anthropic Console](https://console.anthropic.com/settings/organization/api-keys) and create an API key. You'll need credits to use the models.
- Keep the API key safe.
Composio API Key
- Log in to the [Composio dashboard](https://dashboard.composio.dev?utm_source=toolkits&utm_medium=framework_docs).
- Navigate to your API settings and generate a new API key.
- Store this key securely as you'll need it for authentication.

### 2. Install dependencies

No description provided.
```python
pip install composio-anthropic claude-agent-sdk python-dotenv
```

```typescript
npm install @anthropic-ai/claude-agent-sdk @composio/core dotenv
```

### 3. Set up environment variables

Create a .env file in your project root.
What's happening:
- COMPOSIO_API_KEY authenticates with Composio
- USER_ID identifies the user for session management
- ANTHROPIC_API_KEY authenticates with Anthropic/Claude
```bash
COMPOSIO_API_KEY=your_composio_api_key_here
USER_ID=your_user_id_here
ANTHROPIC_API_KEY=your_anthropic_api_key_here
```

### 4. Import dependencies

```python
import asyncio
from claude_agent_sdk import ClaudeSDKClient, ClaudeAgentOptions
import os
from composio import Composio
from dotenv import load_dotenv

load_dotenv()

## Conclusion

You've successfully built a Claude Agent SDK agent that can interact with Rocket reach through Composio's Tool Router.
Key features:
- Native MCP support through Claude's agent framework
- Streaming responses for real-time interaction
- Permission bypass for smooth automated workflows
You can extend this by adding more toolkits, implementing custom business logic, or building a web interface around the agent.

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Rocket reach MCP?

With a standalone Rocket reach MCP server, the agents and LLMs can only access a fixed set of Rocket reach tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Rocket reach and many other apps based on the task at hand, all through a single MCP endpoint.

### Can I use Tool Router MCP with Claude Agent SDK?

Yes, you can. Claude Agent SDK fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Rocket reach tools.

### Can I manage the permissions and scopes for Rocket reach while using Tool Router?

Yes, absolutely. You can configure which Rocket reach scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

### How safe is my data with Composio Tool Router?

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Rocket reach data and credentials are handled as safely as possible.
