How to integrate Heyreach 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 Heyreach.

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

How Atomic Agent connects to Heyreach

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 Heyreach 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 Heyreach. It searches Composio for the right tool.
4. On first use, open the sign-in link returned in the chat. Connect your Heyreach 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 Heyreach MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Heyreach account. It provides structured and secure access to your outreach platform, so your agent can perform actions like managing campaigns, handling leads, creating lists, and automating webhooks on your behalf.

• Campaign management and reporting: Retrieve and review all your active, scheduled, or past campaigns, enabling your agent to keep your outreach strategy organized and up to date.
• Lead and list operations: Fetch all leads from any list, create new empty lists, and get a full overview of your audience segments—making bulk actions and lead tracking a breeze.
• Webhook automation: Set up or delete webhooks programmatically, so your agent can automate notifications and integrate Heyreach data with other tools without manual effort.
• LinkedIn account integration: Access and manage all connected LinkedIn accounts, streamlining multi-channel outreach and coordination directly from your AI assistant.
• Company and data retrieval: Pull companies from specific lists and get detailed records, helping your agent power richer, more personalized engagement workflows.

Use Heyreach from Atomic Agent

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