How to integrate Moosend MCP with Atomic Agent

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 Moosend.

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

How Atomic Agent connects to Moosend

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 Moosend 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 Moosend. It searches Composio for the right tool.
4. On first use, open the sign-in link returned in the chat. Connect your Moosend 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.

The Moosend MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Moosend account. It provides structured and secure access to your email marketing platform, so your agent can perform actions like managing subscribers, automating campaigns, creating mailing lists, and customizing audience data on your behalf.

• Subscriber management and segmentation: Add, update, or search for subscribers in your mailing lists, letting your agent keep your audience organized and up to date.
• Campaign creation and analytics: Retrieve, inspect, and manage email campaigns—enabling your agent to help you monitor, review, or even clean up your marketing activities.
• Mailing list automation: Create or delete mailing lists as needed, so your agent can reorganize or streamline your audience targeting at scale.
• Custom fields and personalization: Build or remove custom fields in your lists, empowering the agent to personalize campaigns and collect richer subscriber data.
• Campaign and list cleanup: Direct your agent to permanently remove campaigns or mailing lists you no longer need, keeping your marketing hub tidy and efficient.

Use Moosend from Atomic Agent

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