Azure Storage Services
When to invoke
- "Which storage access tier should I use for these blobs?"
- "Set up a storage account for file shares or queues."
- "Compare hot, cool, cold, and archive tiers."
- "Configure lifecycle management for old blobs."

MCP Server (Preferred)
When Azure MCP is enabled:
azure__storage with command storage_account_list - List storage accountsazure__storage with command storage_container_list - List containers in accountazure__storage with command storage_blob_list - List blobs in containerazure__storage with command storage_blob_get - Download blob contentazure__storage with command storage_blob_put - Upload blob content
If Azure MCP is not enabled: Run /azure:setup or enable via /mcp.
CLI Fallback

| Hot |
Frequent |
Higher storage, lower access |
| Cool |
Infrequent (30+ days) |
Lower storage, higher access |
| Cold |
Rare (90+ days) |
Lower still |
| Archive |
Rarely (180+ days) |
Lowest storage, rehydration required |

SDK Quick References
For building applications with Azure Storage SDKs, see the condensed guides:
- Blob Storage: Python | TypeScript | Java | Rust
- Queue Storage: Python | TypeScript
- File Shares: Python | TypeScript
- Data Lake: Python
- Tables: Python | Java
For full package listing across all languages, see SDK Usage Guide.
Azure SDKs
For building applications that interact with Azure Storage programmatically, Azure provides SDK packages in multiple languages (.NET, Java, JavaScript, Python, Go, Rust). See SDK Usage Guide for package names, installation commands, and quick start examples.

1---2name: azure-storage-33description: Design and operate Azure Storage services including Blob Storage, File Shares, Queue Storage, Table Storage, and Data Lake, covering object storage, SMB file shares, async messaging, NoSQL key-value data, big data analytics, access tiers, and lifecycle management. Use when the user asks about blob storage, file shares, queue or table storage, Data Lake, uploading files or downloading blobs, storage accounts, hot, cool, cold, or archive access tiers, tier comparison and selection, or storage lifecycle management policies.4license: MIT5---67<!-- Generated from harness/github-copilot/plugins/azure-data-development/skills/azure-storage/SKILL.md by harness/claude-code/scripts/convert_from_copilot.py.
