Verdicts

Backblaze B2

$6.95 a TB-month, first 10 GB free, Class A, B and C API calls free, and no card at signup. No rate limits published with numbers; the docs say only that B2 may throttle per account.

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

Backblaze B2

  1. Take the region from the key's S3 endpoint (the second label of s3.<region>.backblazeb2.com) and pass it as the SDK region
  2. Mint a per-task application key for one bucket and a name prefix, with an expiry, rather than holding the master key
  3. Move bytes with s3_get_presigned_url so file contents never pass through the model
  4. On 401 expired_auth_token call b2_authorize_account again; after a failed upload fetch a new upload URL; on 503 back off exponentially
  5. Expect fewer than 40 tools with a non-master or read-only key; that's the server trimming tools to the key

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
