How to integrate Lucid 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 Lucid.

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

How Atomic Agent connects to Lucid

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 Lucid 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 Lucid. It searches Composio for the right tool.
4. On first use, open the sign-in link returned in the chat. Connect your Lucid 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 Lucid MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Lucid account. It provides structured and secure access to your documents, diagrams, mind maps, sequence diagrams, and org charts, so your agent can search, retrieve, create, edit, and share Lucid content on your behalf.

• Document search and review: Have your agent find documents by title or keyword, search within a document, retrieve its structured content, and summarize what it finds.
• Diagram and chart creation: Direct your agent to create diagrams from specifications, mind maps, sequence diagrams, entity relationship diagrams, and org charts.
• Canvas editing: Let the agent add or edit shapes, lines, and dynamic tables, as well as remove items from an existing Lucid document.
• Sharing and collaboration: Instruct your agent to share documents with collaborators, create share links, review discussion threads, and post comments.
• Organization and export: Have your agent create and manage folders, update document titles or tags, browse folder contents, and export document pages as PNG images.

Use Lucid from Atomic Agent

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