How to Set Up and Use Office 365
The Office 365 MCP Server connects AI agents to Microsoft 365 services through the Microsoft Graph API, providing 24 consolidated tools that cover email, calendar, Teams meetings and channels, OneDrive/SharePoint files, contacts, Planner, To Do, directory lookups, and webhook notifications. It uses OAuth 2.0 delegated authentication with an Azure app registration, storing refreshed tokens locally so users only need to authenticate once. Organizations that want Claude or other AI clients to draft and send emails, schedule meetings, search files, or manage tasks across Microsoft 365 will find this server comprehensive and production-ready.
Prerequisites
- Node.js 18 or higher installed
- A Microsoft 365 account with appropriate licenses (Exchange, Teams, SharePoint, etc.)
- An Azure Active Directory app registration with a client secret and the required delegated Graph API permissions
- The following Graph API permissions granted: Mail.ReadWrite, Calendars.ReadWrite, Files.ReadWrite.All, Teams.ReadWrite.All, Contacts.ReadWrite, Tasks.ReadWrite
- An MCP-compatible client such as Claude Desktop
Clone the repository and install packages
Download the server source code and install the Node.js dependencies.
git clone https://github.com/hvkshetry/office-365-mcp-server.git
cd office-365-mcp-server
npm installRegister an Azure AD application
In the Azure Portal, go to Azure Active Directory → App registrations → New registration. Set the redirect URI to http://localhost:3000/auth/callback. Under API permissions, add delegated Microsoft Graph permissions for Mail, Calendar, Files, Teams, Contacts, and Tasks. Create a client secret under Certificates & secrets.
Create the .env configuration file
Copy the example environment file and fill in your Azure app credentials.
cp .env.example .env
# Edit .env with these values:
OFFICE_CLIENT_ID=your-azure-app-client-id
OFFICE_CLIENT_SECRET=your-azure-app-secret
OFFICE_TENANT_ID=common
OFFICE_REDIRECT_URI=http://localhost:3000/auth/callbackRun the authentication server
Start the local OAuth callback server, then open the printed URL in your browser to authorize the app. Tokens are saved to ~/.office-mcp-tokens.json and auto-refresh thereafter.
npm run auth-serverConfigure your MCP client
Add the server to your Claude Desktop configuration pointing to the index.js entry point.

Authentication fails or browser does not open during 'npm run auth-server'
Ensure the redirect URI in your Azure app registration exactly matches OFFICE_REDIRECT_URI in your .env (including http:// and port 3000). Make sure port 3000 is not in use. If running headlessly, open the printed auth URL manually in a browser on the same machine.
Tool calls fail with '403 Forbidden' from the Graph API
The Azure app is missing the required delegated permissions. In the Azure Portal, go to your app registration → API permissions and verify all needed permissions are added and granted admin consent if required by your tenant.
Tokens expire and the server stops working after a day
The server auto-refreshes tokens from ~/.office-mcp-tokens.json. If refresh fails, re-run 'npm run auth-server' to perform a fresh login. Ensure your Azure app's client secret has not expired.
