What is the Outlook Meetings Scheduler MCP server?

Most team communication work still happens through a UI a human drives. Outlook Meetings Scheduler MCP server moves it into the conversation instead. MCP server for the Outlook Meetings Scheduler.

The short version

MCP Server for scheduling meetings in Microsoft Outlook using Microsoft Graph API.

The tools it exposes

The server publishes 6 tools. What each one is for:

  • Input — name (string)
  • Returns — List of matching people with names and email addresses
  • Inputs — - subject (string): Subject of the calendar event
  • attendees — Array of { email, name (optional), type (optional) }
  • client_credentials — The client_credentials tool exposed by this server
  • client_provided_token — The client_provided_token tool exposed by this server

Getting it running

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

What it needs from you

Configuration is passed through the environment: AUTH_MODE, CLIENT_ID, TENANT_ID, CLIENT_SECRET, USER_EMAIL, ACCESS_TOKEN, TOKEN_EXPIRES_ON, GITHUB_TOKEN. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.

How it compares

Plenty of team communication servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Outlook Meetings Scheduler's toolset — Input, Returns, Inputs and 3 more — is a fair guide to whether it matches your workflow. It is maintained by anoopt; worth a glance at recent repository activity before you build anything load-bearing on it.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

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.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.
