MCP SERVER

Microsoft MCP

by elyxlz ↗

Read and send Outlook mail, move it between folders, book and answer calendar events, keep contacts, and push files in and out of OneDrive — across more than one signed-in Microsoft account, each call naming the account_id it applies to.

Summary
A work mailbox and a personal one answer in the same conversation.

Nearly every tool takes account_id, so two accounts are a parameter rather than a reason to restart the server, and unified_search then spans message, event, drive and site types in one query. The writes are direct: delete_email, delete_event, delete_contact and delete_file each remove the object outright, and the repository declares no license, which matters if this is going into a company setup.

What it is

A server over Microsoft 365 mail, calendar, contacts and OneDrive, holding several signed-in accounts at once and taking account_id on almost every one of its 35 tools.

What you get
  • Mail listed per folder or read one message at a time with body_max_length capping the body, then drafted, sent, replied to sender or to all, flagged or categorised through update_email, moved between folders, or deleted
  • Attachments sent from local file paths and pulled back down by get_attachment to a path you choose
  • Calendar events listed across days_back and days_ahead including recurring instances, created with attendees and a timezone, updated, cancelled with or without a cancellation notice, and answered accept, decline or tentativelyAccept
  • check_availability across a set of attendees before a slot is proposed
  • OneDrive listed by path, downloaded to a local file, uploaded, replaced from a local file and deleted, with contacts created and edited in the same session
  • Search per area — search_emails, search_events, search_files, search_contacts — or unified_search across message, event, drive, driveItem, list, listItem and site in one query
  • Device-code sign-in run from inside the session: authenticate_account returns the URL and code, complete_authentication finishes the flow once it has been entered
Requirements

MICROSOFT_MCP_CLIENT_ID for the Microsoft application the sign-in runs against, and a Microsoft account you can authorize through the device-code flow. The repository declares no license.
