README

outlook-classic-mcp


	A local MCP (Model Context Protocol) server that exposes the classic Outlook desktop client — mail, folders, calendar, contacts, tasks, color categories, mail rules, and Out-of-Office status — to any MCP-aware agent: Claude Code, Claude Desktop, Cowork, GitHub Copilot / VS Code agent mode, Cursor, Cline, Continue, Windsurf, and anything else that speaks MCP.

It talks to Outlook's COM API on Windows via pywin32, the same path macros and Office add-ins use. Authentication piggybacks on whatever account Outlook is already signed into — no Azure / Entra app registration, no Microsoft Graph API, no OAuth tokens.

Requirements

Windows 10 or 11
Outlook desktop (Classic) — the OUTLOOK.EXE shipped with Microsoft 365 / Office. The "new Outlook" (olk.exe) is not supported (no COM surface).
Python 3.10+ (the installer fetches Python 3.11 via uv if you don't already have one).

You do not need to open Outlook before starting the server — the server auto-launches Outlook on its first COM call.

Install

Three paths, simplest first.

Option 1 — Agent plugin (recommended)

The repo doubles as a plugin marketplace. Installing the plugin registers the MCP server and loads the bundled outlook skill (an operational reference that teaches the agent how to drive these tools) in one step. The MCP server itself is fetched on demand by uvx directly from PyPI — no git clone, no pip install, no .venv to maintain.

The plugin format started in Claude Code and is now supported by other agents too (Cowork, Copilot, Cursor, and others that adopted the plugin/skill format) — point your agent's plugin install flow at this repo. The commands below are for Claude Code:

Install uv once if you don't have it:

powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"

Open a fresh terminal so PATH refreshes, then in any Claude Code session:

/plugin marketplace add anasahmed07/Outlook-Classic-MCP
/plugin install outlook@outlook-classic-mcp

Restart Claude Code (/quit, reopen). First call has a one-time 5–15 s pause while uvx resolves the package; subsequent calls are instant. Confirm with outlook_whoami.

To update later: /plugin marketplace update outlook-classic-mcp then /plugin update outlook@outlook-classic-mcp. To pull a fresh PyPI release of the server itself: uv cache clean outlook-classic-mcp.

Option 2 — From PyPI with uv (any MCP client)

Works for any MCP client. The smart client installer auto-registers the server with Claude Desktop, Claude Code, Cursor, Cline, Continue, and Windsurf; for other clients (e.g. VS Code / Copilot agent mode), add the server to their MCP config manually — see below.

uv pip install --system outlook-classic-mcp
python -m outlook_mcp.scripts.install_to_clients

(uv is Astral's Python installer — see Option 1 above for the one-line install. --system writes to your system Python so python -m outlook_mcp resolves anywhere; drop the flag if you'd rather install into an active venv.)

Package: https://pypi.org/project/outlook-classic-mcp/.

Smart client installer

scripts/install_to_clients.py detects which MCP clients are installed on your machine and shows a checkbox menu:

Select which clients to register outlook-mcp with:
  [ ] 1. Claude Desktop      C:\Users\you\AppData\Roaming\Claude\claude_desktop_config.json
  [ ] 2. Claude Code         (via `claude` CLI)
  [ ] 3. Cursor              C:\Users\you\.cursor\mcp.json

Type a number to toggle, 'a' to select all, 'n' for none,
'enter' to confirm, 'q' to quit without changes.
