name: azure-storage description: "Azure Storage Services including Blob Storage, File Shares, Queue Storage, Table Storage, and Data Lake. Answers questions about storage access tiers (hot, cool, cold, archive), when to use each tier, and tier comparison. Provides object storage, SMB file shares, async messaging, NoSQL key-value, and big data analytics. Includes lifecycle management. USE FOR: blob storage, file shares, queue storage, table storage, data lake, upload files, download blobs, storage accounts, access tiers, storage tiers, hot cool cold archive, storage tier comparison, when to use storage tiers, lifecycle management, Azure Storage concepts. DO NOT USE FOR: SQL databases, Cosmos DB (use azure-prepare), messaging with Event Hubs or Service Bus (use azure-messaging)." license: MIT metadata: author: Microsoft version: "1.2.2"

Azure Storage Services

Services

Service	Use When	MCP Tools	CLI
Blob Storage	Objects, files, backups, static content	azure__storage	az storage blob
File Shares	SMB file shares, lift-and-shift	-	az storage file
Queue Storage	Async messaging, task queues	-	az storage queue
Table Storage	NoSQL key-value (consider Cosmos DB)	-	az storage table
Data Lake	Big data analytics, hierarchical namespace	-	az storage fs

MCP Server (Preferred)

When Azure MCP is enabled:

• azure__storage with command storage_account_list - List storage accounts
• azure__storage with command storage_container_list - List containers in account
• azure__storage with command storage_blob_list - List blobs in container
• azure__storage with command storage_blob_get - Download blob content
• azure__storage with command storage_blob_put - Upload blob content

If Azure MCP is not enabled: In Copilot CLI or Claude Code, ask the user to run /mcp and enable Azure MCP; in other hosts, ask the user to enable Azure MCP through the host's MCP configuration.

CLI Fallback

# List storage accounts
az storage account list --output table

# List containers
az storage container list --account-name ACCOUNT --output table

# List blobs
az storage blob list --account-name ACCOUNT --container-name CONTAINER --output table

# Download blob
az storage blob download --account-name ACCOUNT --container-name CONTAINER --name BLOB --file LOCAL_PATH

# Upload blob
az storage blob upload --account-name ACCOUNT --container-name CONTAINER --name BLOB --file LOCAL_PATH

Storage Account Tiers

Tier	Use Case	Performance
Standard	General purpose, backup	Milliseconds
Premium	Databases, high IOPS	Sub-millisecond

Blob Access Tiers

Tier	Access Frequency	Cost
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

Redundancy Options

Type	Durability	Use Case
LRS	11 nines	Dev/test, recreatable data
ZRS	12 nines	Regional high availability
GRS	16 nines	Disaster recovery
GZRS	16 nines	Best durability

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.
