Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "office-excel": {
      "command": "uvx",
      "args": [
        "mcp-office"
      ],
      "env": {
        "EXCEL_ALLOWLIST_ROOTS": "your-value",
        "EXCEL_ENABLE_WRITE": "your-value",
        "EXCEL_ENABLE_COM": "your-value",
        "EXCEL_MAX_ITEMS": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add office-excel --env EXCEL_ALLOWLIST_ROOTS=your-value --env EXCEL_ENABLE_WRITE=your-value --env EXCEL_ENABLE_COM=your-value --env EXCEL_MAX_ITEMS=your-value -- uvx mcp-office

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "office-excel": {
      "command": "uvx",
      "args": [
        "mcp-office"
      ],
      "env": {
        "EXCEL_ALLOWLIST_ROOTS": "your-value",
        "EXCEL_ENABLE_WRITE": "your-value",
        "EXCEL_ENABLE_COM": "your-value",
        "EXCEL_MAX_ITEMS": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "office-excel": {
      "type": "stdio",
      "command": "uvx",
      "args": [
        "mcp-office"
      ],
      "env": {
        "EXCEL_ALLOWLIST_ROOTS": "your-value",
        "EXCEL_ENABLE_WRITE": "your-value",
        "EXCEL_ENABLE_COM": "your-value",
        "EXCEL_MAX_ITEMS": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

EXCEL_ALLOWLIST_ROOTS required env
Comma-separated directory roots allowed for file access. Required — no files are accessible without this.
EXCEL_ENABLE_WRITE env
Set to 'true' to enable write operations (cell writes, sheet creation, formatting).
EXCEL_ENABLE_COM env
Set to 'true' to activate COM-backed tools: recalculate_workbook, export_as_pdf, hydrate_template, pivot_table, and evaluate_formula(live=True). Windows-only — requires pywin32 and Microsoft Excel.
EXCEL_MAX_ITEMS env
Maximum number of rows/items returned per call. Default: 50.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is MCP Office Excel safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: EXCEL_ALLOWLIST_ROOTS

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.7.0) reached the registry 5 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

What can I use instead?

MCP Office

Local-first, governed MCP servers for Microsoft Office — built for developers who want to treat Office files the way they treat code.

What is this?

MCP Office is a suite of Model Context Protocol servers that expose Microsoft Office capabilities as governed, deterministic tool calls. Each server runs locally on Windows, connects to your MCP client (Claude Desktop, VS Code Copilot, or any MCP-compatible client), and gives you structured control over Office files — without an in-app AI assistant.

This is not a Copilot replacement. It is a developer-first execution layer for Office automation.

Packages

✅ Available now

Package	What it does	Install	Tools
`excelmcp`	Read, write, style, validate, and export Excel workbooks	`pip install mcp-office`	65
`pptmcp`	Build, edit, review, and export PowerPoint presentations. Output Contract framework for machine-verifiable slide specs	`pip install mcp-office`	51
`wordmcp`	Template assembly, tracked-changes support, and structural QA for Word documents	`pip install mcp-office`	50

🚧 Coming next

Package	Status
`mailmcp`	Integrated into the current source distribution; Windows Outlook UAT and published-artifact verification pending

MailMCP is now included in the repository's single mcp-office source distribution, but the currently published PyPI artifact does not yet claim MailMCP availability. See mailmcp/README.md for source validation while Windows Outlook UAT and release verification remain open.

New packages are added as they complete their proof cycle. See ROADMAP.md.

Quick start

Prerequisites

Windows 10 or 11
Python 3.11 or later (python --version)
Claude Desktop or VS Code with GitHub Copilot
Microsoft Office (Excel / PowerPoint / Word) — required for COM-backed tools (styling, PDF export, tracked-changes)
Classic Microsoft Outlook desktop — required for MailMCP

Install

PyPI note: excelmcp on PyPI is an unrelated third-party package. Do not pip install excelmcp — that ships you a stranger's code. The published suite package is mcp-office.

pip install mcp-office

Or clone and install the consolidated suite from source (including MailMCP and Windows COM support):

git clone https://github.com/dosev-ai/mcp-office.git

cd mcp-office python -m venv .venv .venv\Scripts\activate python -m pip install -e ".[com]"

Configure Claude Desktop

Open %APPDATA%\Claude\claude_desktop_config.json (create it if it doesn't exist) and add the servers you installed:

"mcpServers": { "excel-excelmcp": { "command": "python", "args": ["-m", "excelmcp.server"], "env": { "EXCEL_ALLOWLIST_ROOTS": "C:\\path\\to\\your\\files", "EXCEL_ENABLE_WRITE": "true" } }, "powerpoint-pptmcp": { "command": "python", "args": ["-m", "pptmcp.server"], "env": { "PPT_ALLOWLIST_ROOTS": "C:\\path\\to\\your\\files", "PPT_ENABLE_WRITE": "true" } }, "word-wordmcp": { "command": "python", "args": ["-m", "wordmcp.server"], "env": { "WORD_ALLOWLIST_ROOTS": "C:\\path\\to\\your\\files", "WORD_ENABLE_WRITE": "true" } } } }

Replace C:\\path\\to\\your\\files with the directory where your Office files live. Restart Claude Desktop after saving.

Verify

In Claude Desktop, send:

Call capabilities() on excel-excelmcp

Call capabilities() on powerpoint-pptmcp Call capabilities() on word-wordmcp

Each should return a tool list (65 for Excel, 51 for PowerPoint, 50 for Word). If a server is missing, check that python resolves to the venv where you installed mcp-office.

Full per-package guides: excelmcp/README.md · pptmcp/README.md · wordmcp/README.md · mailmcp/README.md *(source-integrated; release pending)*

Detailed step-by-step: docs/quickstart.md

Requirements

Requirement	Notes
Windows 10 or 11	COM automation requires Windows
Python 3.11+	`python --version` to confirm
Microsoft Office	Required for COM-dependent tools (styling, PDF export, tracked-changes). Read-only docx/xlsx/pptx tools work without Office.
Classic Outlook desktop	Required for MailMCP. MailMCP remains release-pending until Windows Outlook UAT and published-artifact verification pass.
MCP client	Claude Desktop or VS Code with Copilot

Architecture

Your MCP client (Claude Desktop / VS Code Copilot / other)

│ │ MCP stdio protocol ↓ MCP Office servers (local Python processes) ├─ excelmcp — Excel automation (live) ├─ pptmcp — PowerPoint automation (live) ├─ wordmcp — Word automation (live) └─ mailmcp — Outlook automation (source-integrated; release pending) │ │ COM / Outlook COM / openpyxl / python-pptx / python-docx ↓ Microsoft Office (local installation)

Each server is a standalone local stdio MCP process. MCP Office does not add a hosted service; Microsoft Office and your MCP client/model may still have their own sync and data-handling boundaries.
