⚡ Reliability
Best When
An agent needs to access OneDrive or SharePoint files — for enterprise document management, file automation, or Microsoft 365 storage integration.
Avoid When
You're using Google Drive or Dropbox, or if you need deep Office document editing rather than file-level operations.
Use Cases
- • Reading and writing files stored in OneDrive from document management agents
- • Listing and searching SharePoint document libraries from enterprise content agents
- • Managing shared drive files from collaboration agents
- • Accessing Office documents (Word, Excel, PowerPoint) metadata from productivity agents
- • Synchronizing files across OneDrive from data pipeline agents
- • Searching file content across SharePoint from knowledge management agents
Not For
- • Teams using Google Drive or Dropbox (use their specific MCPs)
- • Teams without Microsoft 365 subscriptions
- • Real-time collaborative Office document editing (use Office Online APIs directly)
Interface

Agent Metadata
Known Gotchas
- ⚠ Azure app registration required — complex setup involving Azure portal, consent, and admin approval
- ⚠ SharePoint site IDs and drive IDs needed for operations — must be discovered via Graph API
- ⚠ File paths in OneDrive use item IDs not POSIX paths — agents must handle ID-based navigation
- ⚠ Large file uploads require upload sessions (not simple PUT) — agents must handle chunked upload
- ⚠ Graph API throttling: Retry-After header must be respected on 429 responses
- ⚠ Official Microsoft MCP — well-maintained but Microsoft Graph auth is complex to set up
