How to integrate Microsoft Word 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 1,700+ apps through Composio, including Microsoft Word.

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 Microsoft Word account. See the Atomic Agent documentation for installation instructions.

For exact tool slugs and parameter tables, see the tool catalog in the Composio docs.

How Atomic Agent connects to Microsoft Word

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 Microsoft Word 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 Microsoft Word. It searches Composio for the right tool.
4. On first use, open the sign-in link returned in the chat. Connect your Microsoft Word 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 Microsoft Word MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Microsoft Word account. It provides structured and secure access to DOCX files in OneDrive and SharePoint, so your agent can find, read, create, edit, and share documents on your behalf.

• Document discovery and reading: Have your agent find DOCX files in OneDrive or SharePoint, inspect their paragraphs, formatting, tables, images, links, and tracked changes, and review retained document versions.
• Document creation and editing: Let the agent create new Word documents, append text and tables, replace text across runs, edit formatting and lists, and update existing content.
• Templates and document workflows: Direct your agent to fill placeholders in a Word template, add comments to specific paragraphs, accept or reject tracked changes, and export a DOCX file to PDF.
• File organization and version control: Instruct your agent to copy, move, rename, replace, delete, or restore DOCX files while preserving access to available document versions.
• Sharing and collaboration: Have your agent create view, edit, or embed sharing links and invite named recipients with read or write access to a DOCX file.

Use Microsoft Word from Atomic Agent

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