Azure Resource Graph Queries for Resource Discovery

Azure Resource Graph (ARG) enables fast, cross-subscription resource querying using KQL via az graph query. Use it for bulk resource discovery and relationship mapping.

How to Query

Use the extension_cli_generate MCP tool to generate az graph query commands:

mcp_azure_mcp_extension_cli_generate
  intent: "query Azure Resource Graph to <describe what you want to find>"
  cli-type: "az"

Or construct directly:

az graph query -q "<KQL>" --query "data[].\{name:name, type:type\}" -o table

⚠️ Prerequisite: az extension add --name resource-graph

Key Tables

Table	Contains
Resources	All ARM resource instances (name, type, location, properties, tags)
ResourceContainers	Subscriptions, resource groups, management groups

Resource Discovery Patterns

List all resources by type:

Resources | summarize count() by type | order by count_ desc

Inventory by location and type:

Resources | summarize count() by type, location | order by type asc

List all resources in a resource group with details:
