# outlook Wires Claude into the classic Outlook desktop client on Windows: mail, calendar, contacts, tasks and rules. Needs Windows 10 or 11 with Outlook desktop installed. - plugin · `type=plugin` · Claude Code · ★ 36 - Author: anasahmed07 - License: MIT · policy=mirror · the beginning of the file is at the end of this page - Source: https://github.com/anasahmed07/Outlook-Classic-MCP - Updated: 2026-10-20 - HTML: https://affpapa.org/en/nevibecode/plugins/outlook ## What it does The plugin registers a local MCP server, `outlook-classic-mcp`, and loads a skill that shows the agent how to use it. The server reaches Outlook through the COM API via `pywin32`, the same route macros and Office add-ins take. Sign-in rides on whatever account Outlook already uses, so there is no Azure app registration, no Microsoft Graph and no OAuth tokens. You get 31 tools prefixed `outlook_*` across nine categories: mail, folders, calendar, contacts, tasks, colour categories, rules and Out-of-Office status. `outlook_whoami` is the sanity check that reports which mailbox is bound. Several read tools ship self-contained HTML views — inbox, reading pane, agenda, contacts, tasks — rendered inside the conversation by hosts that support the MCP Apps extension. Only classic Outlook (`OUTLOOK.EXE`) from Microsoft 365 or Office works. The new Outlook (`olk.exe`) is out, since it has no COM surface. Python 3.10+ is required, and the installer pulls 3.11 through `uv` if you lack one. You don't have to open Outlook first: the server launches it on the first COM call. Expect a one-time 5–15 s pause on that first call while `uvx` resolves the package. ## Install ### Claude Code (native platform) **Plugin marketplace** In the agent chat (not a shell): ```text /plugin marketplace add anthropics/claude-plugins-community ``` In the agent chat (not a shell): ```text /plugin install outlook@claude-community ``` ## When to use it - triage the inbox and file messages into folders - find a message by sender or subject - schedule a meeting and invite attendees - save attachments out of a message - mark tasks complete and add new ones ## Example prompts - List today's unread mail and mark it as read - Find messages from the finance team and save the attachments to `docs` - Create a meeting tomorrow at 15:00 and invite the team ## Source text · SKILL.md · MIT Below is the content of a third-party file.

BEGIN THIRD-PARTY FILE 2f8cfab9dd2347f1 ````text # outlook-classic-mcp ![outlook-classic-mcp banner](src/public/outlook-classic-mcp-banner.png) 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](#agent-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`](https://docs.astral.sh/uv/) once if you don't have it: ```powershell 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: ```text /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. ```bat 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: . --- ## 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. ``` For each toggled client it deep-merges `mcpServers.outlook = {"command": ".venv/Scripts/python.exe", "args": ["-m", "outlook_mcp"]}` into the right config (or runs `claude mcp add` for Claude Code). ```` END THIRD-PARTY FILE 2f8cfab9dd2347f1 The third-party file has ended.
