+ 5 Auth & Attachment Tools

Auth Start — Sign in again or switch to another Microsoft account
Auth Status — Show which Microsoft account is connected
Attachment Read — Extract text from PDF, DOCX, XLSX, images (sender must be approved in browser first)
Whitelist List — Show approved senders for attachment access
Whitelist Revoke — Remove an approved sender

Limitations

What can it not do (yet)?

  • No direct email sending (drafts only — user confirms in Outlook)
  • No attachment uploads (read-only — and only from senders you approve in a browser)
  • No forwarding, redirect or delete rules and no automatic replies — by design, the agent never sends mail on its own (calendar invitations and updates excepted)
  • Cannot permanently delete emails (moving them to the Deleted Items folder is possible)
  • No editing or deleting existing calendar events (except setting categories)
  • No contact access
Connect it

Add this address to your MCP client.

https://mcp-outlook.swarm-test.ci.alpha.pet/mcp

Your client opens a Microsoft sign-in the first time it connects — use your @alpha.pet account. The server acts as you, so each person sees only their own mailbox, and it never sees your password.
