How to integrate Mem 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 Mem.

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

How Atomic Agent connects to Mem

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 Mem 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 Mem. It searches Composio for the right tool.
4. On first use, open the sign-in link returned in the chat. Connect your Mem 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 Mem MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Mem account. It provides structured and secure access to your notes and collections, so your agent can perform actions like creating notes, organizing collections, retrieving note content, and deleting outdated information on your behalf.

• Automated note creation: Ask your agent to quickly capture ideas, meeting summaries, or research notes and save them directly into your Mem workspace.
• Organize with collections: Direct your agent to group related notes by creating new collections for projects, topics, or teams, keeping your knowledge base tidy and efficient.
• Retrieve and review notes: Let your agent fetch the content and metadata of any note by its identifier, making it easy to reference or summarize past information.
• Cleanup and delete notes or collections: Instruct your agent to remove outdated notes or entire collections for a clutter-free knowledge base.

Use Mem from Atomic Agent

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