MCP tools used by vm-creator

The Azure MCP server exposes the compute area as a single namespace proxy: mcp__azure__compute({intent, command, parameters}). The commands below are what the workflow dispatches against it.

Read-only validation (Step 4)

Command	Purpose	Key parameters
compute_vm_list-skus	Confirm SKU availability + filter by vCPU/memory/family	subscription, location, minVCpus, minMemoryGb, familyPrefix, top
compute_vm_list-images	Resolve image alias / URN	subscription, location, publisher, offer, sku
compute_vm_check-quota	Verify vCPU headroom for the family	subscription, location, family
compute_vm_recommend-region	Find regions where the workload fits	workload hints; returns ranked regions

Apply (Step 6, Adapter 4)

Command	Purpose
compute_vm_create	Create a single VM from Plan Card fields
compute_vmss_create	Create a VMSS (adds instance-count, upgrade-policy)
compute_vm_get	Inspect after create
compute_vm_update	Tag changes, size resize, identity attach
compute_vm_delete	Cleanup

See output-adapters/mcp-apply.md for the full parameter mapping and failure-handling table.

CLI fallbacks (when Azure MCP is not connected)

MCP command	CLI equivalent
compute_vm_list-skus	az vm list-skus --location <region> --output table
compute_vm_list-images	az vm image list --location <region> --offer <offer> --all
compute_vm_check-quota	az vm list-usage --location <region> --output table
compute_vm_recommend-region	(no CLI equivalent — fall back to docs)
compute_vm_create	az vm create ... (see az-cli.md)

Why the proxy form matters

The CLI / tool host shows mcp__azure__compute as a single tool. Sub-operations like vm check-quota, vm list-skus, etc. are not separate tools — they are passed through the command parameter. Every command is invoked as:

mcp__azure__compute({
  command: "vm check-quota",
  parameters: { location: "eastus", family: "standardDSv5Family" }
})

When tracing tool calls or writing must-call rubrics, look for the command= argument, not a distinct tool name.
