## Verdicts

**Cloudflare R2.** Free egress and a free tier of 10 GB-month plus 1 million writes a month. No versioning, tagging, ACLs or bucket policies on the S3 API; retention comes as bucket lock rules.

**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.

## Before you call either

### Cloudflare R2

1. Set region to `auto` and the endpoint to https://<account-id>.r2.cloudflarestorage.com. `us-east-1` also works, other region names fail
2. Ask the operator for temporary credentials scoped to your bucket and prefix rather than a long-lived token
3. For public reads put a custom domain or an r2.dev subdomain on the bucket; presigned URLs only sign the S3 hostname
4. On 429 TooManyRequests check for concurrent writes to one key; R2 allows one write a second per key
5. Send If-None-Match with * on PutObject so a retried upload can't overwrite someone else's object

### Google Drive API + MCP

1. Ask for drive.file rather than drive; it needs no verification and covers files the app created or the user picked
2. Use uploadType=resumable for anything over 5 MB and send chunks in multiples of 256 KB
3. For a link that expires, share to a user or group with expirationTime; a type=anyone permission can't expire, so delete it yourself
4. Pass fields= on files.list and files.get to cut the response, and page with pageToken
5. Back off exponentially on 429 rateLimitExceeded and 403 userRateLimitExceeded; 403 storageQuotaExceeded won't clear by retrying
