Which one, for what
Good for Agents working on files that people already keep in Drive, inside a Workspace organisation with admin controls.
Ahead on
- Reliability, 90 against 64
- Security & auth, 91 against 73
- Payments & pricing, 35 against 20
- Maintenance & community, 85 against 75
Also in its favour
- Agent-ready, a grade of BB or better
- No incidents deducted, where OneDrive and SharePoint files (Microsoft Graph) loses 4 points for them
Watch for
OAuth consent, scope verification and a Cloud project before an agent can list a folder
OneDrive and SharePoint files (Microsoft Graph) B
Good for Agents working on files that already live in a Microsoft 365 tenant or a personal OneDrive, where sharing has to follow the tenant's own policy.
Ahead on
- Schema & documentation, 89 against 83
Watch for
Link and scope types are plain strings in the OpenAPI, and path addressing such as /root:/folder/file.txt: is absent from it

Verdicts
Google Drive API + MCP
No charge for API calls within quota, counted in quota units per minute per project and per user. OAuth consent, scope verification and a Cloud project before an agent can list a folder.
OneDrive and SharePoint files (Microsoft Graph)
One REST surface covers personal OneDrive, work OneDrive and SharePoint libraries, with resumable uploads, sharing links that take an expiry date and per-file Selected permissions. The status page needs JavaScript, an app must be registered and consented to by a person, and the JavaScript client on npm lacks a token-leak fix merged in June 2026.
Before you call either
Google Drive API + MCP
- Ask for drive.file rather than drive; it needs no verification and covers files the app created or the user picked
- Use uploadType=resumable for anything over 5 MB and send chunks in multiples of 256 KB
- For a link that expires, share to a user or group with expirationTime; a type=anyone permission can't expire, so delete it yourself
- Pass fields= on files.list and files.get to cut the response, and page with pageToken
- Back off exponentially on 429 rateLimitExceeded and 403 userRateLimitExceeded; 403 storageQuotaExceeded won't clear by retrying
OneDrive and SharePoint files (Microsoft Graph)
- Use PUT
/contentonly up to 250 MB. Above 10 MiB Microsoft advisescreateUploadSession, with fragments in multiples of 320 KiB and under 60 MiB each - Send the bearer token on the
createUploadSessionPOST only. The PUT calls touploadUrlcan return 401 if anAuthorizationheader is included - Set
expirationDateTimeandscopeoncreateLink. Without a scope the tenant's default link type is created, which may be wider than intended - Follow the 302 from GET
/contentstraight away. Pre-authenticated download URLs can expire within minutes and need noAuthorizationheader - Wait for
Retry-Afteron 429 and 503. Throttled requests still count against the limits, and continued overuse can get the app blocked
