Iris runs on your own machine — the client starts it, so there is no endpoint to ping. 409 installs a week from pypi. Last commit 10 Sep 2026.
Microsoft 365 mail MCP: drafts into Outlook; sending off by default, opt-in via IRIS_ENABLE_SEND.
Today is the operative word: we check Iris every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

This one needs environment variables set before it will start:
IRIS_CLIENT_ID (Application (client) ID of YOUR OWN Entra app registration. There is no shared app; you register one.), IRIS_TENANT_ID (Directory (tenant) ID. Defaults to 'organizations'.), IRIS_DRAFT_FOLDER (Mail folder drafts are written to, created on first use. Defaults to 'AI Drafts'. Empty string uses Drafts.), IRIS_ALLOWLIST (Path to a recipient allowlist file. If absent or empty, all recipients are permitted.), IRIS_ENABLE_SEND (Set to '1' to enable sending. ALSO requires Mail.Send granted on the Entra app and a fresh sign-in. Off by default; when unset, iris cannot send and the send tool is not registered.).
The author declared them in the registry entry; get the values from the project itself.
