Egress to the internet is billed per GB after 100 GB a month.\n\n**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.\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### Dropbox API + MCP\n\n1. Use files/upload under 150 MiB and upload_session above it; append in multiples of 4 MiB and finish within 7 days\n2. 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\n3. Set expires on create_shared_link_with_settings only on a paid account; a Basic account gets an error\n4. Keep the list_folder cursor and call list_folder/continue instead of re-listing\n5. On a rate-limit error wait retry_after seconds; too_many_write_operations means write contention, so serialise writes\n\n## Other comparisons with Amazon S3 or Dropbox 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 Google Drive API + MCP](https://www.anchorterminal.com/compare/amazon-s3-vs-google-drive-api.md)\n- [Backblaze B2 vs Dropbox API + MCP](https://www.anchorterminal.com/compare/backblaze-b2-vs-dropbox-api.md)\n- [Cloudflare R2 vs Dropbox API + MCP](https://www.anchorterminal.com/compare/cloudflare-r2-vs-dropbox-api.md)\n- [Dropbox API + MCP vs Tigris](https://www.anchorterminal.com/compare/dropbox-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 Dropbox API + MCP](https://www.anchorterminal.com/compare/box-api-vs-dropbox-api.md)\n- [Dropbox API + MCP vs Google Drive API + MCP](https://www.anchorterminal.com/compare/dropbox-api-vs-google-drive-api.md)\n", "meta": { "attribution": "Anchor Terminal (https://www.anchorterminal.com)", "docs": "https://www.anchorterminal.com/docs/", "generatedAt": "2026-10-05", "license": "CC-BY-4.0", "method": "https://www.anchorterminal.com/benchmark/", "methodology": "0.3", "openapi": "https://www.anchorterminal.com/openapi.json", "preview": false, "run": "2026-10-01", "runLabel": "October 2026 research run" }, "page": { "breadcrumbs": [ { "name": "Home", "url": "https://www.anchorterminal.com/" }, { "name": "Compare", "url": "https://www.anchorterminal.com/compare/" }, { "name": "Amazon S3 vs Dropbox API + MCP", "url": "" } ], "description": "Amazon S3 has a score of 79.3 (A) against Dropbox API + MCP's 68.2 (B).
