Excel Workbook Operations Via Graph

via “excel file operations and onenote notebook access”

A Model Context Protocol (MCP) server for interacting with Microsoft 365 and Office services through the Graph API

Unique: Uses Graph API's workbook session management for transactional consistency across multiple cell updates, preventing race conditions in concurrent scenarios. Implements OneNote page append operations through Graph API's /content endpoint with HTML content support.

vs others: More reliable than OpenPyXL or similar libraries because it works with cloud-stored files without local download/upload cycles. More integrated than REST-based Excel APIs because it leverages Microsoft's official Graph API with built-in session management.

via “chart creation and management”

** - Excel manipulation including data reading/writing, worksheet management, formatting, charts, and pivot table

Unique: Exposes chart creation as a discrete MCP tool that accepts data ranges and chart specifications, enabling agents to generate visualizations without understanding Excel's chart object hierarchy

vs others: Simpler than using Excel's COM API because it abstracts chart object creation and data binding into a single tool call with declarative parameters

via “excel-workbook-operations-via-graph”

** 📇 ☁️ - MCP server that connects to the whole Microsoft 365 suite (Microsoft Office, Outlook, Excel) using Graph API (including mail, files, calendar)

Unique: Wraps Graph Excel API's session-based workbook model into stateless MCP tool calls, automatically managing workbook sessions and translating A1 cell notation into Graph API range queries without requiring agents to understand Excel's internal object model

vs others: More integrated than generic spreadsheet APIs because it works with Excel's table model and formula evaluation, and simpler than Excel COM automation because it doesn't require local Excel installation and works across cloud-hosted workbooks
