## Introduction

This guide walks you through connecting LeadBoxer to the Claude Agent SDK using the Composio tool router. By the end, you'll have a working LeadBoxer agent that can list all new leads from today, show all companies visiting pricing page, get contact info for most recent lead through natural language commands.
This guide will help you understand how to give your Claude Agent SDK agent real control over a LeadBoxer account through Composio's LeadBoxer 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 LeadBoxer
- Configure an AI agent that can use LeadBoxer as a tool
- Run a live chat session where you can ask the agent to perform LeadBoxer 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 LeadBoxer MCP server, and what's possible with it?

The LeadBoxer MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your LeadBoxer account. It provides structured and secure access so your agent can perform LeadBoxer operations on your behalf.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `LEADBOXER_ADD_OR_UPDATE_LEAD_TAGS` | Add or Update Lead Tags | Tool to add or update lead tags in LeadBoxer. Use when you need to manage lead tags by adding new tags, removing specific tags, or overwriting all existing tags for a specified user. |
| `LEADBOXER_DELETE_CTD` | Delete Custom Tracking Domain | Tool to delete a custom tracking domain entry for a dataset. Use when you need to remove a specific custom tracking domain (CTD) associated with a dataset in LeadBoxer. |
| `LEADBOXER_GET_EVENTS` | Get Events | Tool to fetch events for specified sessions from LeadBoxer. Use when you need to retrieve behavioral data including pageviews, clicks, form submissions, email interactions, and custom events. Events can be filtered by session ID, email, user ID, or segment/smartlist IDs. |
| `LEADBOXER_GET_LEAD_SCORE_FORMULA` | Get Lead Score Formula | Tool to fetch the lead score formula for a specific dataset. Use when you need to understand how lead scores are calculated for records in a dataset. The formula defines scoring based on criteria types: Range (number ranges), Match (exact values), Exists (presence of values), and Boost (event-based scoring). |
| `LEADBOXER_GET_SESSIONS` | Get Sessions | Tool to fetch sessions for a specified lead ID from LeadBoxer. Use when you need to retrieve session data for a user, with optional filtering by email, user ID, Smartlist ID, or segment ID. A session represents a single visit to the site, and users can have multiple sessions over time. |
| `LEADBOXER_LOG_SERVER_SIDE_EVENT` | Log Server-Side Event | Tool to track server-side events in LeadBoxer. Use when tracking backend events, page views, or custom activities from your server. This endpoint supports tracking user interactions, conversions, and other activities that occur on the server-side. |
| `LEADBOXER_GET_CUSTOM_TRACKING_DOMAINS` | Get Custom Tracking Domains | Tool to fetch custom tracking domain entries for a dataset. Use when you need to retrieve all custom tracking domains that are created or in progress for a specific datasetId. |
| `LEADBOXER_POST_EVENT_DATA` | Post Event Data | Tool to send event data for tracking user activities via POST request. Use when tracking events by sending data in the request body with application/x-www-form-urlencoded format. |
| `LEADBOXER_GET_LEAD_DETAIL` | Get Lead Detail | Tool to fetch detailed information about a lead based on filters. Use when you need comprehensive lead data for a specific lead ID. The default view type is B2B. Note: On initial pageview, there may be a few seconds overhead before data is populated; consider implementing a 3-second delay after lead creation. |

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

The LeadBoxer MCP server is an implementation of the Model Context Protocol that connects your AI agent to LeadBoxer. It provides structured and secure access so your agent can perform LeadBoxer 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 LeadBoxer 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

No description provided.
```python
import asyncio
from claude_agent_sdk import ClaudeSDKClient, ClaudeAgentOptions
import os
from composio import Composio
from dotenv import load_dotenv

load_dotenv()
```

import 'dotenv/config';
import readline from 'node:readline';
import { Composio } from '@composio/core';

## Conclusion

You've successfully built a Claude Agent SDK agent that can interact with LeadBoxer 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 LeadBoxer MCP?

With a standalone LeadBoxer MCP server, the agents and LLMs can only access a fixed set of LeadBoxer tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from LeadBoxer 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 LeadBoxer tools.

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

Yes, absolutely. You can configure which LeadBoxer 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 LeadBoxer data and credentials are handled as safely as possible.
