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: Run /azure:setup or enable via /mcp.

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
