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**Tigris.** No egress fees, and one endpoint (t3.storage.dev) with region auto for every location. 16 status incidents between 4 July and 2 October 2026, including outages in US regions on 31 July and 2 August.\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### Tigris\n\n1. Point the AWS SDK at https://t3.storage.dev with region `auto`; the stdio MCP README still shows the older fly.storage.tigris.dev endpoint\n2. Ask for an access key with a ReadOnly or ReadWrite role on one bucket rather than an org-wide key\n3. Keep presigned URLs short; Tigris accepts up to 90 days\n4. Don't call tigris_list_objects on a large bucket; it walks every object with no limit or prefix\n5. Use @tigrisdata/iam 2.6.0 or later before writing policies with conditions\n\n## Questions\n\n### Which is better for AI agents, Azure Blob Storage or Tigris?\n\nAzure Blob Storage scores 75.7 (BB) on agent readiness against Tigris's 44.4 (E), and leads in 6 of 7 scored categories. Tigris leads on payments \u0026 pricing.\n\n### Do Azure Blob Storage and Tigris need an API key?\n\nBoth take an API key or an OAuth sign-in.\n\n### Can an agent call Azure Blob Storage and Tigris without installing anything?\n\nYes.
