SharePoint MCP Server

A Model Context Protocol (MCP) server that provides Claude with access to Microsoft SharePoint via the Microsoft Graph API.

Features

• Folder Management: List, create, delete folders and view folder tree structure
• Document Operations: Upload, download, read, update, and delete documents
• Metadata Support: Get and update file metadata fields
• OAuth 2.0 Authentication: Secure user-based authentication via browser flow
• Consistent Architecture: Same modular pattern as Outlook MCP for easy maintenance

Troubleshooting

"Authentication required" error

• Ensure you've run the auth server and completed browser authentication
• Check that tokens are stored in ~/.sharepoint-mcp-tokens.json

"AADSTS7000215" error

• You're using the Secret ID instead of the Secret Value
• Go back to Azure and copy the actual secret value

"Access denied" error

• Ensure admin consent was granted for the API permissions
• Verify the site URL is correct
