Microsoft Outlook MCP Server

MCP server for Microsoft Outlook — search, send, and manage mail and calendar with browser-session auth; no Azure AD app registration.

Clone the repo, build it, point your AI tool at dist/index.js. Uses the same OWA REST API that Outlook Web App calls internally. Auth is your normal Outlook browser login; access matches what your account can already do.

Prerequisites

  • Node.js 18+

  • Microsoft 365 / Outlook.com account

  • Chrome (macOS/Linux) or Edge (Windows)

Related MCP server: outlook-mcp

Setup

git clone https://github.com/hickeroar/outlook-mcp.git
cd outlook-mcp
npm install
npm run build

Register as a local stdio MCP server:

{
  "mcpServers": {
    "Outlook": {
      "command": "node",
      "args": ["/absolute/path/to/outlook-mcp/dist/index.js"]
    }
  }
}

Session files: ~/.outlook-mcp-server/ (macOS/Linux) or %APPDATA%\outlook-mcp-server\ (Windows).

First login

Call outlook_login (use forceNew: true if session is dead). Browser opens for Microsoft sign-in. After that, tools use cached OWA tokens with automatic refresh.

Commands

npm run build
npm run typecheck
npm run cli -- status
npm run cli -- login
npm run cli -- inbox
npm run cli -- search "quarterly report"
npm run cli -- calendar
