## Introduction

This guide walks you through connecting Gumroad to the Claude Agent SDK using the Composio tool router. By the end, you'll have a working Gumroad agent that can show all sales from the past week, list active subscriptions for your e-book, get your gumroad profile details through natural language commands.
This guide will help you understand how to give your Claude Agent SDK agent real control over a Gumroad account through Composio's Gumroad 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 Gumroad
- Configure an AI agent that can use Gumroad as a tool
- Run a live chat session where you can ask the agent to perform Gumroad 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 Gumroad MCP server, and what's possible with it?

The Gumroad MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Gumroad account. It provides structured and secure access to your Gumroad business data, so your agent can review sales, manage subscriptions, handle webhook resources, and retrieve user profile details on your behalf.
- Sales data insights: Instantly pull reports on all successful sales, with options to filter by date, product, or customer email for real-time business tracking.
- Subscription management: Let your agent list, review, and manage all active resource subscriptions, making it easy to keep tabs on recurring customers and memberships.
- User profile retrieval: Fetch up-to-date profile details for your Gumroad account, giving your agent context for personalized actions or reporting.
- Webhook automation: Subscribe or unsubscribe from Gumroad resources to receive real-time event notifications, enabling seamless integration with your automation workflows.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `GUMROAD_GET_RESOURCE_SUBSCRIPTIONS` | Get Resource Subscriptions | Tool to show all active subscriptions of the user for the input resource. Use when you need to review existing webhooks before adding a new one. |
| `GUMROAD_GET_SALES` | Get Sales | Tool to retrieve all successful sales by the authenticated user; excludes failed charges, abandoned carts, and page views — conversion rates cannot be derived from this data. Use when you need to list your Gumroad sales, optionally filtering by email, date range, product, or pagination. For high sales volumes, combine product_id and/or after/before filters with page to avoid large unfiltered result sets. |
| `GUMROAD_GET_USER` | Get User | Tool to retrieve the authenticated user's data. Use when you need the current user's profile details after authentication. |
| `GUMROAD_LIST_PRODUCTS` | List Products | Tool to retrieve all products for the authenticated Gumroad account. Use when you need product IDs for downstream operations like license verification, subscriber retrieval, or offer-code management. |
| `GUMROAD_SUBSCRIBE_TO_RESOURCE` | Subscribe to Resource | Tool to subscribe to a resource. Use when you need to receive real-time event webhooks after creating your webhook endpoint. |
| `GUMROAD_UNSUBSCRIBE_FROM_RESOURCE` | Unsubscribe From Resource | Tool to unsubscribe from a resource. Use after verifying the subscription ID exists to remove webhook. |
| `GUMROAD_VERIFY_LICENSE` | Verify License | Tool to verify a Gumroad license key against a specific product. Use when you need to check if a license key is valid, check usage count, or verify membership entitlement for software licensing or gated content. |

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

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

## Frequently Asked Questions

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

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

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

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