OneNote MCP Server: Integrating AI Applications into Microsoft OneNote

Overview: What is OneNote MCP Server?

OneNote MCP Server is an implementation of the Model Context Protocol (MCP) designed to enable AI applications and language models to interact with Microsoft OneNote through a standardized interface. This server acts as a bridge, facilitating seamless communication between various AI tools and the OneNote notebook ecosystem. By leveraging MCP, developers can ensure that AI applications like Claude Desktop, Continue, Cursor, and more have consistent and robust access to critical data, enhancing productivity and efficiency in note-taking and content creation workflows.

🔧 Core Features & MCP Capabilities

This server offers a comprehensive set of core features centered around managing OneNote notebooks, sections, and pages. These capabilities are essential for AI applications that aim to integrate with Microsoft OneNote:

• Notebook Management: List all notebooks, create new ones, retrieve details about existing notebooks, and delete them when necessary.
• Section Management: List sections within a notebook, add new sections, obtain section details, and remove sections as needed.
• Page Management: List pages within a section, create new pages with HTML content, read page content, update it, and delete pages. Additionally, the server supports searching for pages across multiple notebooks.

These features provide a robust foundation for AI applications to interact dynamically with OneNote, allowing for real-time data manipulation and integration.

⚙️ MCP Architecture & Protocol Implementation

The architecture of OneNote MCP Server follows the Model Context Protocol (MCP), which is designed to ensure interoperability between various AI tools. The server uses Microsoft Azure services for authentication and authorization, ensuring secure access to OneNote resources via its APIs. Internally, it manages connections to the Microsoft Graph API to perform CRUD operations on notebooks, sections, and pages.
