Egress to the internet is billed per GB after 100 GB a month.\n\n**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.\n\n## Before you call either\n\n### Amazon S3\n\n1. Hold STS session credentials scoped by a session policy, never a long-lived IAM user key\n2. Sign presigned URLs with credentials that outlive the URL; a URL signed with a one-hour session token dies with the token\n3. Send If-None-Match with * on PutObject so a retry can't overwrite a file another call wrote\n4. Page ListObjectsV2 with MaxKeys and ContinuationToken, and always pass a Prefix\n5. On 503 SlowDown back off and spread keys over more prefixes, since each prefix gets 3,500 writes a second\n\n### Google Drive API + MCP\n\n1. Ask for drive.file rather than drive; it needs no verification and covers files the app created or the user picked\n2. Use uploadType=resumable for anything over 5 MB and send chunks in multiples of 256 KB\n3. For a link that expires, share to a user or group with expirationTime; a type=anyone permission can't expire, so delete it yourself\n4. Pass fields= on files.list and files.get to cut the response, and page with pageToken\n5. Back off exponentially on 429 rateLimitExceeded and 403 userRateLimitExceeded; 403 storageQuotaExceeded won't clear by retrying\n\n## Other comparisons with Amazon S3 or Google Drive API + MCP\n\n- [Amazon S3 vs Box API + MCP](https://www.anchorterminal.com/compare/amazon-s3-vs-box-api.md)\n- [Amazon S3 vs Dropbox API + MCP](https://www.anchorterminal.com/compare/amazon-s3-vs-dropbox-api.md)\n- [Backblaze B2 vs Google Drive API + MCP](https://www.anchorterminal.com/compare/backblaze-b2-vs-google-drive-api.md)\n- [Cloudflare R2 vs Google Drive API + MCP](https://www.anchorterminal.com/compare/cloudflare-r2-vs-google-drive-api.md)\n- [Google Drive API + MCP vs Tigris](https://www.anchorterminal.com/compare/google-drive-api-vs-tigris.md)\n- [Amazon S3 vs Backblaze B2](https://www.anchorterminal.com/compare/amazon-s3-vs-backblaze-b2.md)\n- [Amazon S3 vs Bunny Storage](https://www.anchorterminal.com/compare/amazon-s3-vs-bunny-storage.md)\n- [Amazon S3 vs Cloudflare R2](https://www.anchorterminal.com/compare/amazon-s3-vs-cloudflare-r2.md)\n- [Amazon S3 vs Tigris](https://www.anchorterminal.com/compare/amazon-s3-vs-tigris.md)\n- [Box API + MCP vs Google Drive API + MCP](https://www.anchorterminal.com/compare/box-api-vs-google-drive-api.md)\n- [Dropbox API + MCP vs Google Drive API + MCP](https://www.anchorterminal.com/compare/dropbox-api-vs-google-drive-api.md)\n",
