How to integrate Elorus 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 Elorus.

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

How Atomic Agent connects to Elorus

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 Elorus 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 Elorus. It searches Composio for the right tool.
4. On first use, open the sign-in link returned in the chat. Connect your Elorus 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 Elorus MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Elorus account. It provides structured and secure access to your invoicing, billing, and time-tracking tools, so your agent can perform actions like creating invoices, managing contacts, tracking estimates, and sending billing communications on your behalf.

• Automated invoice creation and delivery: Instruct your agent to generate new invoices, fill in all necessary details, and instantly email them to clients or contacts with just a prompt.
• Comprehensive contact management: Ask your agent to fetch, list, and organize your business contacts, so you can easily keep your client database up to date or find specific clients in seconds.
• Dynamic bills and expenses tracking: Let your agent retrieve and manage lists of bills and expenses, helping you stay on top of accounts payable and overall financial health.
• Flexible product and service catalog management: Direct your agent to create new products or services, update details, or fetch lists of items for invoicing and inventory purposes.
• Estimates and credit notes retrieval: Have your agent pull up estimates or credit notes with filters for date, contact, or status—ideal for monitoring ongoing deals and financial adjustments.

Use Elorus from Atomic Agent

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