excel-mcp-server

Why we included this project

Teams that automate reporting usually reach a point where an AI needs to build or edit a spreadsheet, and this server is what makes that practical. It exposes Excel operations as callable tools over the Model Context Protocol, letting an agent create, read, and edit workbooks, add formulas, style cells, and build charts and pivot tables, all without needing Microsoft Excel installed. Run it locally over stdio or as a remote service over streamable HTTP, and any MCP-compatible client can talk to it. The built-in validation around ranges, formulas, and data integrity matters more than it sounds, because a careless agent editing an .xlsx file can quietly corrupt the whole workbook.
