    List every folder of the Outlook.com mailbox with its path, total message count and unread count.

Install Mail-MCP in Claude Code, Cursor or VS Code

Runs npx -y @rixtay/mail-mcp on your machine. Read the scan report first; the gateway never runs local packages.

What the publisher says

From the Mail-MCP repository's README, as published. We do not edit it. Read it on GitHub

Mail-MCP

A small, focused MCP server that lets Claude (Claude Desktop, Cowork, Claude Code or any MCP client) work on a personal Outlook.com / Hotmail / Live mailbox through Microsoft Graph: read and search mail, file it into folders, delete it, and unsubscribe from newsletters.

Built for one job: clean up an overflowing personal inbox with an AI assistant, safely.

Tools

Nine tools, all prefixed mail_:

Design choices:

  • Safe by default. Deletion goes to Deleted Items (visible and restorable in Outlook). Permanent deletion requires an explicit flag. Bulk actions support dryRun.
  • Efficient on big mailboxes. mailsenderssummary scans thousands of messages in a few seconds (1,000-item pages, minimal $select) and only fetches headers for the top senders through $batch.
  • No generic send tool. The Mail.Send permission is used solely to send mailto: unsubscribe requests.
  • Every tool ships a strict input schema, an output schema and MCP annotations (readOnlyHint, destructiveHint, …) so hosts can auto-approve read-only calls.

Requirements

  • Node.js 22 or newer.
  • A personal Microsoft account (outlook.com, hotmail.com, live.com, msn.com).
  • A free Microsoft Entra app registration (5 minutes, below). Password-based IMAP was switched off for personal accounts in September 2024, so an OAuth app is the only supported way in.

1. Register an app in Microsoft Entra (once, free)

No Azure subscription is needed for a public client app.

  1. Go to and sign in with your personal Microsoft account.
  2. Identity → Applications → App registrations → New registration.
  3. Fill in:
  • Name: Mail-MCP
  • Supported account types: Personal Microsoft accounts only
  • Redirect URI: platform Mobile and desktop applications, value http://localhost
  1. Click Register and copy the Application (client) ID (xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx).
  2. Under Authentication, make sure http://localhost is listed under "Mobile and desktop applications" and Allow public client flows is Yes.
  3. Under API permissions, add Microsoft Graph delegated permissions: Mail.ReadWrite, Mail.Send, User.Read, offline_access. No admin consent is needed; you consent at first sign-in.

Shortened. The full README is on GitHub.
