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.

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)

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 from source (for development / COM extras):

git clone https://github.com/dosev-ai/mcp-office.git
cd mcp-office
python -m venv .venv
.venv\Scripts\activate
pip install -e ./excelmcp
pip install -e ./wordmcp
pip install -e ./shared && pip install -e ./pptmcp

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, 46 for PowerPoint, 50 for Word). If a server is missing, check that python resolves to the venv where you installed mcp-office.

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. | | 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 + MailRepo (coming)
        │
        │  COM / openpyxl / python-pptx / python-docx
        ↓
  Microsoft Office (local installation)

Each server is a standalone stdio MCP server. No network calls. No cloud dependency. Your files stay local.
