Excel MCP Server
Manipulate Excel files locally or remotely with zero Microsoft Excel installation required. Pure Python implementation using openpyxl-style operations under the hood. Three transport modes: stdio for local use, SSE marked deprecated, and Streamable HTTP for remote production deployments. The Streamable HTTP transport requires EXCEL_FILES_PATH set on the server side and rejects absolute paths plus directory traversal, so remote deployments are sandboxed by default. 3,767 stars and 413 forks make this the highest-traction Excel MCP by a wide margin. v0.1.x release stream signals an evolving API surface, but the daily-near release cadence and PyPI distribution as `excel-mcp-server` keep operators on a known upgrade path. For data analysts wanting agent-driven Excel automation, this server delivers the full Excel feature surface (formulas, formatting, charts, pivot tables, conditional formatting) without the Microsoft Office licensing dependency.
