## Introduction

This guide walks you through connecting Campayn to the Claude Agent SDK using the Composio tool router. By the end, you'll have a working Campayn agent that can add new subscriber to weekly newsletter list, list all active contact lists in account, fetch details for your last sent campaign through natural language commands.
This guide will help you understand how to give your Claude Agent SDK agent real control over a Campayn account through Composio's Campayn 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 Campayn
- Configure an AI agent that can use Campayn as a tool
- Run a live chat session where you can ask the agent to perform Campayn 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 Campayn MCP server, and what's possible with it?

The Campayn MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Campayn account. It provides structured and secure access to your contact lists, email campaigns, and subscriber management, so your agent can handle tasks like creating contacts, managing lists, fetching messages, and maintaining your email marketing automation—all on your behalf.
- Effortless contact management: Easily add new contacts, update existing ones, or permanently delete subscribers from your Campayn lists through your agent.
- Automated list organization: Ask your agent to create, retrieve, or clean up contact lists, making it simple to segment and manage your audience.
- Campaign and message insights: Have your agent fetch the details of individual messages or retrieve all campaign messages to keep you up to date with your email marketing efforts.
- Streamlined webform management: Direct your agent to delete outdated or unnecessary webforms, keeping your lead capture workflow tidy and current.
- Bulk data retrieval: Let your agent pull all contacts in a specific list or fetch all available lists with a single command, saving you time and effort when working with large datasets.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `CAMPAYN_CREATE_CONTACT` | Create Contact | Tool to create a new contact in a specific list. Use when you need to add a contact after gathering details. |
| `CAMPAYN_DELETE_CONTACT` | Delete Contact | Tool to delete a specific contact. Use when you need to remove a contact permanently after confirming it should be deleted. Example: "Delete contact 123". |
| `CAMPAYN_DELETE_LIST` | Delete List | Tool to delete a specific contact list. Use when cleaning up unused lists after confirming they are no longer needed. Example: "Delete list 123". |
| `CAMPAYN_DELETE_WEBFORM` | Delete webform | Delete a specific webform from a contact list. Use this to permanently remove a webform that is no longer needed. Requires both the list_id and webform_id - use Get Webforms action first to find these values. Note: The API returns success even for non-existent webform IDs (idempotent delete behavior). |
| `CAMPAYN_GET_CONTACT` | Get Contact | Tool to retrieve a specific contact by ID. Use when you need to fetch full contact details after confirming the contact ID. |
| `CAMPAYN_GET_CONTACTS` | Get Contacts | Retrieves all contacts from a specific contact list in Campayn. Returns contact details including email, name, address, and confirmation status. Use 'Get Lists' action first to obtain the list_id. Supports optional filtering by contact name/email/company. |
| `CAMPAYN_GET_LISTS` | Get Lists | Tool to retrieve all contact lists. Use when you need to fetch available lists before performing list-specific actions. Example prompt: "List all my contact lists". |
| `CAMPAYN_GET_MESSAGE` | Get Message Statistics | Tool to retrieve engagement statistics for a specific email message by ID. Returns views, positive responses (clicks), and negative responses (unsubscribes/bounces). Use GET_MESSAGES first to get the list of available message IDs. |
| `CAMPAYN_GET_MESSAGES` | Get Messages | Tool to retrieve all email messages. Use when you need to list all messages visible to the authenticated user. |
| `CAMPAYN_GET_REPORTS` | Get Reports | Tool to retrieve report URLs and metadata for sent and scheduled emails. Use when you need to fetch email delivery data, optionally filtered by a date range (Unix timestamp in seconds, UTC). Note: scheduled emails will have report_url set to null. |
| `CAMPAYN_GET_WEBFORM` | Get Webform | Tool to retrieve details of a specific webform by ID. Use after confirming the webform ID when you need to fetch form details like title, type, HTML, and signup count. Example: "Get webform 1550". |
| `CAMPAYN_GET_WEBFORMS` | Get Webforms | Tool to retrieve all webforms for a specific contact list. Use when you need to list forms after confirming the list ID. Example prompt: "List all webforms in list 123". |
| `CAMPAYN_UNSUBSCRIBE_CONTACT` | Unsubscribe Contact | Tool to unsubscribe contacts from a list by contact id or email address. Use when you need to remove contacts from a mailing list. If id is provided, only that specific contact will be unsubscribed. If email is provided, all contacts on that list with that email will be unsubscribed. |
| `CAMPAYN_UPDATE_LIST` | Update List | Tool to update a contact list. Use after confirming list ID and desired changes. Example: Update list 123 name to 'Newsletter Subscribers'. |

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

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

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Campayn MCP?

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

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

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