Introduction

Atomic Agent is an open-source AI agent that runs on your machine and supports local models through llama.cpp. Connect it to 1,500+ apps through Composio, including Gumroad.

This guide uses Atomic Agent's built-in Composio integration. You need Atomic Agent v0.5.6 or later, your own Composio API key, and a Gumroad account. See the Atomic Agent documentation for installation instructions.

How Atomic Agent connects to Gumroad

Atomic Agent connects to Composio's Tool Router over Streamable HTTP MCP. It discovers the tools needed for your request, and Composio handles account authentication.

Execution and account-connection tools follow Atomic Agent's configured approval policy. Review any approval prompt before allowing an action on your connected account.

Connect Gumroad to Atomic Agent

  1. Sign up or sign in to the Composio dashboard. Copy your API key.
  2. In Atomic Agent, open the Integrations tab and select Composio. Select API key, press e, paste the key, and press Enter. The tools become available immediately, without a restart.
  3. Ask Atomic Agent to do something in Gumroad. It searches Composio for the right tool.
  4. On first use, open the sign-in link returned in the chat. Connect your Gumroad account, then return to Atomic Agent to continue.

Headless setup

Add the following line to ~/.atomic-agent/.env, replacing YOUR_COMPOSIO_API_KEY with your key. Start Atomic Agent after saving the file.

bash
COMPOSIO_API_KEY=YOUR_COMPOSIO_API_KEY

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.

Use Gumroad from Atomic Agent

With your account connected, ask Atomic Agent to work with Gumroad in natural language. You can connect more apps through the same Composio integration as you need them.

Troubleshooting

Why is my API key rejected?

Copy the key directly from the Composio dashboard. Atomic Agent requires ASCII characters because it sends the key in an HTTP header. Remove any extra characters introduced when copying.

Why are Composio tools unavailable after saving a key?

Check that you use Atomic Agent v0.5.6 or later and that Composio is enabled in your configuration. A "composio": { "enabled": false } setting disables the integration while keeping the saved key on disk.

Does Composio have a free plan?

The Hobby plan includes 100,000 tool calls per month. Composio-managed OAuth apps have a lower included allowance. See Composio pricing for the current limits that apply to your connection.

FAQ

Frequently asked questions

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.

Yes, you can. Atomic Agent 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.

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.

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.
