Nothing serious here today

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 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.

run in your terminal
claude mcp add iris -- uvx iris-mcp

{
  "mcpServers": {
    "iris": {

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.

Iris — questions

Answers built from our own checks of this server.

Why is there no uptime for Iris?
Iris runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the pypi package iris-mcp was installed 409 times last week.
How do I connect Iris?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls iris-mcp straight from pypi; nothing to host, nothing to sign up for.
How many people use Iris?
The pypi package iris-mcp was installed 409 times in the last week. Week over week that is +210%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Iris open source?
Yes — it is published under the MIT licence, written in Python and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
