Microsoft365 MCP Server

jordanburke · MCP server(filed by default)

Microsoft365 MCP Server connects your AI assistant to Microsoft 365 through Microsoft Graph. Its 73 tools span mail, calendar, contacts, files, Teams, Planner, OneNote, To Do and SharePoint sites. Your agent can search and read messages, write threaded draft replies for you to review in Outlook before sending, find meeting times when everyone is free and browse OneDrive and SharePoint files. It needs your own Azure app registration, supports several sign-in modes and registered accounts, and its Teams, Planner and SharePoint tools need org mode.

Written by ooruby from the README of microsoft365-mcp-server 1.2.12.

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

Why it's useful

Your agent can work across your Microsoft 365 mail, calendar and files, and you can restrict it to drafts or read-only access.

What you could do with it

  1. 1Ask your agent to write a threaded reply to a message and leave it in your Drafts folder for review.
  2. 2Have your agent suggest meeting times when all the participants are free.
  3. 3Search OneDrive and SharePoint for a file through your agent and download it.

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

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 1.2.12, the file with digest sha512-Bg7dvhhURLXycMtb2AZUybfeo2FQECPpOayvKMdBqlni25+d9QJ8C+5wQLSwAeInTgLX4jGgC5/stBsNOKSt8Q==, 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": {
    "microsoft365-mcp-server": {
      "command": "npx",
      "args": [
        "-y",
        "microsoft365-mcp-server@1.2.12"
      ]
    }
  }
}

Or run it directly.

npx -y microsoft365-mcp-server@1.2.12

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.
