FAQ from Mcp Office Excel
What dependencies does Mcp Office Excel require?
It requires Python 3.11+ and runs on Windows. Microsoft Excel (desktop version) is only needed for COM‑based tools (PDF export, recalculation, pivot tables, VBA); the file‑based tools (using openpyxl) work without Excel.
How does Mcp Office Excel differ from hosted cloud‑based Excel automation?
Mcp Office Excel is local‑first — all processing happens on your machine. There is no hosted or cloud tier, so your workbook data never leaves your environment.
What transport protocol does Mcp Office Excel use?
The server communicates over stdio, as is standard for MCP servers. No network transport or authentication is required.
Are there any known limitations?
The server offers 65 tools, but COM‑dependent features require a licensed copy of Microsoft Excel installed on the same Windows machine. The file‑based subset works without Excel.
Where does my workbook data live?
All data stays on your local filesystem. The server reads from and writes to Excel files on disk; it does not send data to any remote service.
