Outlook MCP server

outlook-mcp

MCP server for Microsoft Outlook personal accounts via Microsoft Graph API.

Personal Microsoft accounts only — @outlook.com, @hotmail.com, @live.com. Work/school accounts (Entra ID) are not supported in v1.

Who this is for

You'll like this if you're:

• An agent builder wiring Outlook into your own infra (OpenClaw, Claude Code, Cursor, custom MCP host) and want a typed tool surface — not stdout you have to parse
• Building on personal Microsoft accounts (Outlook.com / Hotmail / Live) and want full control: BYO Azure app, no enterprise consent flow, no shared client ID
• Looking for real coverage — mail, calendar, contacts, to-do, drafts, folders, batch ops, threading — instead of a mail-only or calendar-only wrapper
• Security-conscious: tokens in the OS keyring (Keychain on macOS, libsecret on Linux -- never cleartext unless you opt in), granular allowcategories, optional readonly mode, zero telemetry

This isn't for you if you need work/school M365 accounts (use Microsoft's official tooling — Entra ID auth and admin-consent flows are out of scope here), or if a basic mail-only client would suffice (this has 62 tools — way more than you need for "read my inbox").

How it differs from other Outlook tools you'll find

This is the only first-class MCP server in the personal-Outlook space — most alternatives are bash scripts or skill-shaped CLI wrappers the agent shells out to. That distinction matters: the agent gets typed tool schemas with structured args/returns, not stdout it has to parse. Other things you won't find elsewhere: /$batch-optimized triage (10-20× faster on bulk ops), recursive folder ops with name resolution, granular per-category permissions, multi-account support, and full attachment write paths including >3MB upload sessions for drafts.

What This Enables

Give your AI agent full Outlook access. Example prompts that just work:

• "Summarize my unread email from the past 24 hours and flag anything time-sensitive."
• "What's in my Focused Inbox right now? Anything in Other that looks like it belongs up top?"
• "Any shipping updates in my inbox? Track what I'm waiting on and when it's supposed to arrive."
• "Scan my email for upcoming subscription renewals — what's about to auto-charge in the next two weeks?"
• "I've got a trip to Seattle next week — check my calendar for the itinerary and create a To Do task with a packing checklist."
• "Draft a reply to the last message from my sister saying I'll call her this weekend."
• "Move all newsletter and promotional email from this week to a 'Read Later' folder — batch 20 at a time."

The server exposes 62 discrete tools so the agent can compose its own workflow — read, triage, write, schedule, track tasks — without hardcoded macros.

Works With

• OpenClaw — native MCP support, available via ClawHub
• Claude Code — add to ~/.claude/settings.json under mcpServers
• Cursor — MCP-compatible
• Any MCP client — it's a standard stdio MCP server
