How to connect a OneNote MCP with Claude Code (4 steps)

Merge provides a seamless way to integrate OneNote with Claude Code using the Merge Agent Handler, simplifying the process of accessing institutional knowledge stored in OneNote without the need for a complex Microsoft Graph integration. The Merge platform manages authentication and token refreshes through a single CLI setup, allowing developers to list notebooks, retrieve page content, and summarize notes directly from the terminal. This integration is particularly beneficial for developers needing to access meeting notes, project specifications, and architecture decisions that are often stored in OneNote but not integrated into standard development workflows. By connecting OneNote to Claude Code, developers can efficiently access and utilize this information for coding or downstream actions, addressing gaps in existing Microsoft Graph implementations and providing a scalable solution for multi-user environments.
