## Which one, for what

### Dropbox API + MCP (B)

Good for: An agent acting on a person's or team's existing Dropbox files, especially a solo user on the free plan.

Ahead on:
- Payments & pricing, 35 against 20
- Maintenance & community, 90 against 75

Also in its favour:
- No incidents deducted, where OneDrive and SharePoint files (Microsoft Graph) loses 4 points for them

Watch for: MCP server is beta, extracts at most 5 MB per file and can be blocked by team admins

### 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:
- Reliability, 64 against 52
- Agent ergonomics, 84 against 77
- Transparency & trust, 75 against 62

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

**Dropbox API + MCP.** Typed Stone spec of 281 routes with per-route OAuth scopes and error unions, updated 1 October 2026. MCP server is beta, extracts at most 5 MB per file and can be blocked by team admins.

**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

### Dropbox API + MCP

1. Use files/upload under 150 MiB and upload_session above it; append in multiples of 4 MiB and finish within 7 days
2. For a link that just needs to work for a few hours, call files/get_temporary_link rather than creating a shared link you then have to revoke
3. Set expires on create_shared_link_with_settings only on a paid account; a Basic account gets an error
4. Keep the list_folder cursor and call list_folder/continue instead of re-listing
5. On a rate-limit error wait retry_after seconds; too_many_write_operations means write contention, so serialise writes

### OneDrive and SharePoint files (Microsoft Graph)

1. Use PUT `/content` only up to 250 MB. Above 10 MiB Microsoft advises `createUploadSession`, with fragments in multiples of 320 KiB and under 60 MiB each
2. Send the bearer token on the `createUploadSession` POST only. The PUT calls to `uploadUrl` can return 401 if an `Authorization` header is included
3. Set `expirationDateTime` and `scope` on `createLink`. Without a scope the tenant's default link type is created, which may be wider than intended
4. Follow the 302 from GET `/content` straight away. Pre-authenticated download URLs can expire within minutes and need no `Authorization` header
5. Wait for `Retry-After` on 429 and 503. Throttled requests still count against the limits, and continued overuse can get the app blocked
