Office Outlook MCP

chrischall · MCP server

Connects an AI assistant to Outlook and Microsoft 365 for mail, folders, calendar, contacts and tasks. It can list and read messages and attachments, create drafts, send mail, mark or move messages, and create or update calendar events with a Microsoft Teams meeting attached by default. It can also ask Outlook's Scheduling Assistant for times when everyone is free. Anything that writes asks you to confirm first.

Written by ooruby from the README of @chrischall/office-outlook-mcp 0.4.1.

Not claimed by its maker. Is this yours? Prove it and answer the findings

Why it's useful

Your agent can handle mail and meeting scheduling in Outlook while you approve every change that sends or edits something.

What you could do with it

  1. 1Ask your agent to find a time when everyone invited is free and create the event with a Teams meeting.
  2. 2Have your agent write a draft email and show exactly what would be sent before you approve it.
  3. 3Go through a folder of messages, mark the ones you have dealt with as read and move others elsewhere.

Written from its documentation: what it says it can do, not what our checks found.

Maintenance

Not measured

No release date is on record for this package yet. The nightly publisher check records one as it reaches each npm package, about once every ten nights.

Release activity only: it says nothing about quality or safety, and a finished small package can be fine without releases. How it is measured

Not yet tested
Licence and provenance
finding
no LICENCE file at the root (.)

Published because it was found. A finding is information about where the limits are, not a verdict that the software is unsafe.

How far this has been checked

Static scanned

What it establishes
Its published package, or for a hosted server its source repository at a recorded commit, was read file by file, without running it, by every check in our current scan.
What it does not
How it behaves when it runs, or anything the scan does not read yet: several rubric checks, the repository's history, and compiled code in folders named dist or build. For a hosted server, that the endpoint runs the code that was read. The ooruby Index sets out exactly what was read.
Exactly what was read
Version 0.4.1, the file with digest sha512-OlgWzOxBOtIEKHFOccwzUZY1XR59BDocBUPT2G3E1tdKBmXMlVGIuDrCd7jTe24msTWmLGKPc1Hl0y9pMWsARg==, as the registry publishes it. A published version cannot be replaced, so this names the same bytes for anyone who checks.
Authentication
Runs locally. No hosted endpoint is listed for this package. You run it on your own machine, so there is no endpoint of ours to authenticate against.
How the rungs work

Adding it

Paste this into your client's MCP configuration.

{
  "mcpServers": {
    "office-outlook-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "@chrischall/office-outlook-mcp@0.4.1"
      ]
    }
  }
}

Or run it directly.

npx -y @chrischall/office-outlook-mcp@0.4.1

Pinned to 0.4.1, which is the version the findings above were found in. Drop the version to take whatever is newest, and the report on this page stops describing what you installed.

The badge, if this is your listing

It renders the current rung (static scanned) and links back here, where what that does and does not establish is one click away. It updates itself as the evidence deepens.
