Overview

AI-generated overview

A local MCP server that lets an assistant create and edit Excel workbooks on your machine, working with rows and sheets.

What you can do
Create Excel workbooks locally, with rows and sheets as the building blocks of each file. Edit existing workbooks by changing rows and sheets. Everything happens on the local machine, with no network calls and no API key.
When to use it
Useful when you want an assistant to produce or adjust spreadsheet files on your own computer, such as assembling tabular data into a workbook or updating rows and sheets in an existing file, without involving a cloud service.
Requirements
Runs as a local process on the user's machine, installed from the npm package @mrfentmen/excel-mcp over stdio, so a Node.js runtime is needed. No authentication, environment variables or headers are declared. Desktop only; not available as a web executable.
Before you install
It writes and edits workbook files on your local disk, so changes to existing files may not be reversible; keep backups of anything important. No credentials or network access are involved according to the description.

Installation

In SourceWeft

  1. Open Excel Mcp in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.
