How to integrate Better proposals 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 Better proposals.

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 Better proposals account. See the Atomic Agent documentation for installation instructions.

How Atomic Agent connects to Better proposals

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 Better proposals 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 Better proposals. It searches Composio for the right tool.
4. On first use, open the sign-in link returned in the chat. Connect your Better proposals 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 Better Proposals MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Better Proposals account. It provides structured and secure access to your proposals workspace, so your agent can perform actions like creating companies, generating proposals, listing templates, and managing document types on your behalf.

• Automated proposal creation: Instruct your agent to generate new proposal covers or assemble entire proposals using customizable templates and dynamic content.
• Company and client management: Let your agent create new companies, retrieve lists of existing clients, and keep your contacts organized for faster proposal delivery.
• Template and document type selection: Ask your agent to fetch available templates and document types, helping you choose the right style and format every time.
• Quote and currency handling: Have your agent list all available quotes and supported currencies, streamlining the pricing and invoicing process for your proposals.
• Bulk data retrieval and reporting: Direct the agent to gather lists of all proposals, document types, or companies for easy review, reporting, or dashboarding.

Use Better proposals from Atomic Agent

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