### Description (declared)

# Microsoft 365 MCP Server

An [MCP](https://modelcontextprotocol.io) server that exposes Microsoft 365
operations as tools, backed by Microsoft Graph — SharePoint, OneDrive, Mail,
Calendar, Users & Directory, and Groups — plus text extraction from Office/PDF
documents and mail attachments.

It is **stateless** and **does not do any OAuth**: your application already holds
a valid Microsoft Graph access token, and it supplies that token with each
request. No re-authentication, no token exchange, no gateway.

## Why this exists

If you already obtained a Microsoft Graph delegated access token
(`aud = https://graph.microsoft.com`) via a 3LO flow in your app, you cannot feed
that token into an On-Behalf-Of (OBO) exchange — Entra requires the OBO assertion
to target a middle-tier app, not Graph itself. This server avoids the problem
entirely by calling Graph directly with the token you already have.

## Install & run with uvx

The server ships as a `uvx`-runnable package. [`uv`](https://docs.astral.sh/uv/)
builds and runs it in an isolated environment on demand — no manual `pip install`.

Once published to an index you can run it by name:

```bash
uvx keos-microsoft365-mcp
```

## Providing the access token

The token is resolved per request in this order:

1. **Explicit argument** — pass `access_token` in the tool call arguments.
2. **Bearer header** — when running over HTTP, send `Authorization: Bearer <token>`.
3. **Environment** — `GRAPH_ACCESS_TOKEN` (or the legacy `SHAREPOINT_ACCESS_TOKEN`).

The token must be a Microsoft Graph delegated access token
(`aud = https://graph.microsoft.com`). Grant the scopes for the tools you use:

| Area | Delegated scopes |
|------|------------------|
| SharePoint / OneDrive / Groups files | `Sites.Read.All` / `Sites.ReadWrite.All`, `Files.Read.All` / `Files.ReadWrite.All`, `Group.Read.All` |
| Mail | `Mail.Read`, `Mail.ReadWrite`, `Mail.Send` |
| Calendar | `Calendars.ReadWrite` |
| Users & Directory | `User.Read.All`, `Directory.…
