• File Operations: Browse, search, upload, and download files

• Document Libraries: Access and manage document libraries

• Sharing: Create sharing links for files

• Search: Full-text search across SharePoint

• Lists: Read and create SharePoint list items

• OAuth Authentication: Secure browser-based login with automatic token refresh

• Structured Output: All responses use Pydantic models for type safety

Restart Claude Desktop. The first time you use a SharePoint command, a browser window will open for authentication.

Option B: Using uv --directory (For Development)

Clone this repository and add to your Claude Desktop config:

Option C: Using Claude Code

2. Call upload_file with the content

3. Confirm the upload

2. Call create_sharing_link with link_type="view" and expiration_days=7

3. Return the shareable URL

Azure AD App Setup

You need to register an application in Azure AD to use this MCP server. See the detailed guide: docs/azure-setup.md

Quick summary:

1. Go to Azure Portal → Azure Active Directory → App registrations

2. Create a new registration:

   • Name: "SharePoint MCP Server"

   • Supported account types: "Accounts in this organizational directory only"

   • Redirect URI: Web → http://localhost:8765/callback

3. Add API permissions:

   • Microsoft Graph → Delegated permissions:

     • Sites.Read.All

     • Files.ReadWrite.All

     • User.Read

     • offline_access

   • Grant admin consent (if required)

4. Authentication → Enable "Allow public client flows"

5. Copy the Client ID and Tenant ID for your configuration

Troubleshooting

Authentication Issues

Problem: "Missing configuration" error

Solution: Ensure you've set AZURE_CLIENT_ID and AZURE_TENANT_ID environment variables in your MCP config.

Problem: Browser doesn't open for authentication

Solution: The server starts a local web server on port 8765. Ensure this port isn't blocked by a firewall.

Problem: "Authentication timed out"

Solution: Complete the authentication within 2 minutes. If you miss the window, try the command again.

Re-authentication

To clear stored tokens and re-authenticate:

Then restart Claude Desktop and try a SharePoint command again.

Permission Errors

Problem: "Access denied" or "Insufficient permissions"

Solution:

1. Verify the Azure AD app has the required permissions

2. Ensure admin consent has been granted (if required by your organization)

3. Check that your Microsoft account has access to the SharePoint site/file

Debug Logging

Enable debug logging by setting LOG_LEVEL=DEBUG in your MCP config:

Check logs at:

• macOS: ~/Library/Logs/Claude/mcp-server-sharepoint.log

• Windows: %APPDATA%\Claude\Logs\mcp-server-sharepoint.log

Limitations

• File size: Downloads limited to 10MB (configurable in code)

• Pagination: List operations return up to 200 items per page (use cursor for more)

• Search: Uses Microsoft Search, results depend on indexing

• Rate limiting: Graph API has rate limits; the client implements automatic retry with backoff

Security

• OAuth tokens are stored securely in your OS keychain (macOS Keychain, Windows Credential Manager, Linux Secret Service)

• No passwords are stored - only temporary OAuth tokens

• Automatic refresh - access tokens are refreshed automatically before expiration

• Local callback server - runs only during authentication, binds to localhost only
