Account keys with full access stay enabled until the owner turns them off, request logs are off until configured, and an Azure account needs a person, a phone number and a payment card.\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### Azure Blob Storage\n\n1. Request an Entra ID token for https://storage.azure.com/ and send it as a Bearer header with `x-ms-version` and `x-ms-date`. Put Blob also needs `x-ms-blob-type: BlockBlob`\n2. Ask for a Storage Blob Data role on the one container. Role changes can take up to 10 minutes to apply\n3. To share a file, call Get User Delegation Key, then sign a SAS with `sp=r`, `spr=https` and a short expiry. Treat the URL as a secret\n4. Send `If-None-Match: *` on Put Blob so a retry can't overwrite a blob another call wrote\n5. On 503 ServerBusy back off exponentially. After 500 OperationTimedOut check the blob's state before retrying, since the write may have succeeded\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## Questions\n\n### Which is better for AI agents, Azure Blob Storage or Dropbox API + MCP?\n\nAzure Blob Storage scores 75.7 (BB) on agent readiness against Dropbox API + MCP's 68.2 (B), and leads in 4 of 7 scored categories. Dropbox API + MCP leads on schema \u0026 documentation, payments \u0026 pricing and maintenance \u0026 community.\n\n### Do Azure Blob Storage and Dropbox API + MCP need an API key?\n\nAzure Blob Storage takes an API key or an OAuth sign-in. Dropbox API + MCP uses an OAuth sign-in.\n\n### Can an agent call Azure Blob Storage and Dropbox API + MCP without installing anything?\n\nYes.
