Mail-MCP runs on your own machine — the client starts it, so there is no endpoint to ping. 74 installs a week from npm. Last commit 1 Oct 2026.
Personal Outlook.com / Hotmail inbox: read, search, file, delete, unsubscribe via Microsoft Graph.
Today is the operative word: we check Mail-MCP every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

This one needs environment variables set before it will start:
MAIL_MCP_CLIENT_ID (Application (client) ID of your Microsoft Entra app registration (see README). Run `npx -y @rixtay/mail-mcp login` once to sign in.), MAIL_MCP_CACHE_PATH (Token cache location. Defaults to ~/.mail-mcp/token-cache.json.).
The author declared them in the registry entry; get the values from the project itself.
