excel-mcp-server is an open-source ai agents project by haris-musa (haris-musa/excel-mcp-server on GitHub). It has 4,216 GitHub stars and 470 forks, is released under the MIT license, and was last updated on GitHub on 8 October 2026.
Choose the folder(s) the server may access — access is confined to --allow-dir paths.
Add the uvx command to Claude Code, Codex, or another MCP client using the documented one-liners.
Restart so the Excel tools load.
Have the agent read a sheet, compute values, and write results or a chart back into the file.
Read/write ranges, formatting, conditional formatting, data validation, tables, images, and sparklines.
Formula results are calculated by a built-in engine (~260 functions), not left as unevaluated strings.
Create Excel charts including 2016 types, and build PivotTables from your data.
Folder confinement, formula safety checks that reject network/external-reference functions, atomic saves, and an optional read-only mode.
Run locally per-client over stdio, or as a streamable-HTTP server with optional token authentication.
Reads VBA in macro-enabled files; writing VBA is opt-in (--allow-vba-write) and macros are never executed.
Clone the project and enter its directory (most users run it via uvx, next step).
git clone https://github.com/haris-musa/excel-mcp-server.git
cd excel-mcp-serverRegister the server, scoped to your workbooks folder.
claude mcp add excel --scope user -- uvx excel-mcp-server stdio --allow-dir /path/to/workbooksStart the server over stdio yourself, or over HTTP at http://127.0.0.1:8017/mcp.
uvx excel-mcp-server stdio --allow-dir /path/to/workbooksDeveloper haris-musa maintains the project (excelmcpserver.com).
Yes, MIT-licensed. Your AI client (Claude, Codex, etc.) may have its own costs.
Neither — no Excel installation is required, and the server itself needs no key; HTTP mode can optionally use your own auth token.
This server gives the agent purpose-built, safety-checked tools (confinement, formula checks, atomic saves, a real calculation engine) instead of arbitrary code execution against your files.
Run `claude mcp add excel --scope user -- uvx excel-mcp-server stdio --allow-dir /path/to/workbooks`, restart Claude Code, and ask it to inspect a workbook.
