How to Set Up and Use Microsoft 365
The Microsoft 365 MCP Server by Softeria exposes over 200 tools covering the Microsoft Graph API, giving AI assistants direct access to Outlook email, Calendar, OneDrive, Excel, OneNote, Teams, SharePoint, and more through a single MCP interface. It supports both personal Microsoft accounts and organizational work/school accounts (via --org-mode), and includes a token-efficient output format that reduces context usage by 30-60% on large list operations. Teams and individuals use it to automate email triage, schedule meetings, manage files, and retrieve Teams messages without leaving their AI workflow.
Prerequisites
- Node.js 18+ installed (for npx execution)
- A Microsoft personal account or work/school account (Azure AD/Entra ID)
- An MCP client such as Claude Desktop or Claude Code
- For org-mode: appropriate Microsoft 365 license with Teams and SharePoint access
- Optional: Azure app registration (MS365_MCP_CLIENT_ID and MS365_MCP_TENANT_ID) for custom OAuth credentials
Run the server with npx (personal account)
For personal Microsoft accounts, run the server directly with npx. It will prompt you to authenticate via a browser on first run.
npx -y @softeria/ms-365-mcp-serverEnable org mode for work/school accounts
Work and school accounts need --org-mode to unlock Teams, SharePoint, and shared mailbox tools.
npx -y @softeria/ms-365-mcp-server --org-modeAuthenticate your Microsoft account
On first launch the server prints a browser URL for OAuth authentication. Open it, sign in with your Microsoft account, and grant the requested permissions. Credentials are cached for subsequent runs.
Configure Claude Desktop
Add the server to your Claude Desktop configuration. Use --org-mode if connecting a work account. The server reads env vars for customization.

"ms365": {
"command": "npx",
"args": ["-y", "@softeria/ms-365-mcp-server", "--org-mode"],
"env": {
"MS365_MCP_OUTPUT_FORMAT": "toon"
}
}
}
}Add to Claude Code CLI
Register the server via the Claude Code CLI for project-level use.
claude mcp add ms365 -- npx -y @softeria/ms-365-mcp-server --org-modeReduce context usage with compact output format
Set MS365_MCP_OUTPUT_FORMAT=toon to enable a compact representation that cuts token usage by 30-60% on list operations like fetching emails or calendar events.

- "Schedule a 30-minute meeting with [email protected] tomorrow at 2pm"
- "List the files in my OneDrive root folder and find anything modified this week"
- "Get the last 10 messages from the #engineering Teams channel"

Authentication fails or browser URL does not open
Copy the printed URL manually and open it in a browser. If you are behind a corporate proxy, ensure the OAuth redirect (localhost) is reachable. Re-run the server after completing browser sign-in.
Teams or SharePoint tools are missing
These tools are only available in org mode. Add --org-mode to the args array in your config and re-authenticate with your work or school account.
Responses are very large and hitting context limits
Set MS365_MCP_OUTPUT_FORMAT=toon in the env block to enable compact output, and set MS365_MCP_MAX_TOP to a lower number (e.g., 20) to cap the number of results returned per list call.
