Excel automation for AI - Sheets, Power Query, DAX, VBA, Tables, Ranges and more. Windows only.

Overview

MCP Server for Excel's local MCP server; no sign-in required; STDIO.

No AI overview yet: these facts come from the registry entry and the server itself.

Installation

In SourceWeft

  1. Open MCP Server for Excel 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.

Other MCP clients

Follow the launch instructions in the repository.

Website · Installation · Features · Troubleshooting · 2-minute demo

Automate real Microsoft Excel with AI. Excel MCP Server lets GitHub Copilot, Claude, ChatGPT, and other agents control Excel through natural-language requests—using either MCP or a token-efficient CLI.

Unlike file-parser tools, ExcelMcp drives the actual Excel application through its official COM API. It can refresh Power Query, recalculate formulas, evaluate DAX, run VBA and Python =PY(), and preserve PivotTables, charts, macros, the Data Model, and workbook formatting.

64 MCP tools across 33 feature areas, with 437 operations, cover end-to-end Excel automation.

[!IMPORTANT] Requires Windows, Microsoft Excel 2016 or later, and an interactive desktop. It is not intended for Linux, macOS, or server-side batch processing.

For GitHub Copilot CLI, install either plugin from the Awesome Copilot Excel listings:

powershell
copilot plugin install excel-mcp@awesome-copilot# Or, for command-line Excel automation:copilot plugin install excel-cli@awesome-copilot

For a workbook already open in Excel, use discovery and attachment to keep working in that workbook. Excel determines whether newly opened files are read-only.

What You Can Automate

  • Data & analytics: Power Query, DAX, Power Pivot, Excel Tables, PivotTables, and data connections.
  • Cells & workbooks: ranges, formulas, formatting, worksheets, files, calculation, and named ranges.
  • Charts & visuals: charts, slicers, conditional formatting, screenshots, drawings, and sparklines.
  • Automation & advanced: VBA, Python in Excel, Goal Seek, scenarios, data tables, windows, and XML Maps.

Explore the capabilities behind all 437 operations. Current command details come from CLI help or the MCP tool descriptions.

See It in Action

[A sales table, regional summary, and chart created in the real Excel application by Excel MCP Server]

Ask in plain language:

  • "Import products.csv with Power Query and load it to the Data Model."
  • "Create a PivotTable showing revenue by region, then add a column chart."
  • "Use Goal Seek to find the price that produces $100,000 profit."
  • "Show me Excel while you work."

Because Excel performs the work, you can inspect results live and continue editing the workbook normally.

MCP Server or CLI?

Both entry points expose the same Excel commands and behavior, so the choice is technical. Coding agents can use either one.

InterfaceWorks withWhy
MCP ServerAny MCP-compatible clientTool discovery and persistent sessions
CLI (excelcli)Agents that can run terminal commandsBuilt-in help without loading MCP tool definitions, usually with fewer AI tokens

Both entry points run Excel commands in separate worker processes, so a blocked Excel operation does not block their basic controls. The CLI also keeps a background service running so workbook sessions persist across commands.

SourceWeft started this package once in an isolated sandbox, without credentials, to list its tools. That failed: the server did not start.

Score

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
