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 Curated.

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 Curated account. See the Atomic Agent documentation for installation instructions.

How Atomic Agent connects to Curated

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 Curated 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 Curated. It searches Composio for the right tool.
  4. On first use, open the sign-in link returned in the chat. Connect your Curated 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 Curated MCP server, and what's possible with it?

The Curated MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Curated account. It provides structured and secure access to your newsletters, letting your agent manage publications, curate content, draft issues, and handle subscribers for you.

  • Publication and issue management: Have your agent list all your publications, fetch their issues, and help you stay on top of what's scheduled or published.
  • Draft issue creation: Let your agent create new draft issues for any of your newsletters, making it easy to start new editions with the right content and settings.
  • Curated link collection: Easily add new links, articles, or resources to your publication's collection, so your newsletter always has fresh, relevant content.
  • Subscriber insights: Retrieve lists of all email subscribers for any publication, helping you better understand and engage your audience.
  • Category organization: List and review all categories for your publications, allowing your agent to help you keep content organized and targeted.

Use Curated from Atomic Agent

With your account connected, ask Atomic Agent to work with Curated 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 Curated MCP server, the agents and LLMs can only access a fixed set of Curated tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Curated 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 Curated tools.

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