What is the Outlook Calendar MCP MCP server?

MCP server for Outlook Calendar integration. That is what the outlook calendar mcp mcp server brings to an AI assistant: the same capability, reachable through the Model Context Protocol rather than a separate app or dashboard.

The short version

A Model Context Protocol (MCP) server that allows Claude to access and manage your local Microsoft Outlook calendar (Windows only).

  • View Calendar Events — List events within a date range, view event details, check attendee status
  • Manage Calendar Events — Create new events and meetings, update existing events
  • Calendar Intelligence — Find free time slots for scheduling, identify optimal meeting times
  • Multiple Calendar Support — Access different calendars in your Outlook profile

What it needs from you

  • Windows operating system - Microsoft Outlook desktop client installed - VBScript support (see VBScript Installation below if you're on Windows 11 24H2+) - Node.js (version 14.x or higher) - npm (comes with Node.js)

Getting it running

outlook-calendar-mcp on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.

How it compares

This sits in the planning and project tracking group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. It is maintained by merajmehrabi; worth a glance at recent repository activity before you build anything load-bearing on it.

We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.

Things to watch

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.
