Agent Skill

Azure Resource Lookup

azure-resource-lookup

List, find, and show Azure resources across subscriptions or resource groups. Handles prompts like "list the websites in my subscription", "list my web apps", "show my app services", "list virtual machines", "list my VMs", "show storage accounts", "find container apps", and "what resources do I have". USE FOR: list websites, list web apps, list app services, show websites in subscription, resource inventory, find resources by tag, tag analysis, orphaned resource discovery (not for cost analysis), unattached disks, count resources by type, cross-subscription lookup, and Azure Resource Graph queries. DO NOT USE FOR: deploying/changing resources (use azure-deploy), cost optimization (use azure-cost), or non-Azure clouds.

Summary

The Azure Resource Lookup agent skill enables developers to quickly list, find, and discover Azure resources of any type, identify orphaned resources, and audit tag compliance across multiple subscriptions and resource groups. This agent skill is invaluable for developers, DevOps engineers, and cloud architects needing to gain quick inventory insights, audit resource configurations, or identify underutilized assets within their Azure estates. This is an emerging or highly specialized skill with limited adoption so far. It primarily leverages Azure Resource Graph (ARG) and Kusto Query Language (KQL) to perform fast, cross-cutting queries across subscriptions and resource groups. The skill guides the AI agent to generate `az graph query` commands for tasks like listing all VMs, finding container apps, discovering orphaned resources, or auditing for missing tags. It is important to note this skill is read-only, specifically designed for discovery and inventory, and should not be used for deploying, modifying, or real-time monitoring of Azure resources.

Skill Definition

List, find, and discover Azure resources of any type across subscriptions and resource groups. Use Azure Resource Graph (ARG) for fast, cross-cutting queries when dedicated MCP tools don't cover the resource type.

When to Use This Skill

Use this skill when the user wants to:

  • List resources of any type (VMs, web apps, storage accounts, container apps, databases, etc.)
  • Show resources in a specific subscription or resource group
  • Query resources across multiple subscriptions or resource types
  • Find orphaned resources (unattached disks, unused NICs, idle IPs)
  • Discover resources missing required tags or configurations
  • Get a resource inventory spanning multiple types
  • Find resources in a specific state (unhealthy, failed provisioning, stopped)
  • Answer "what resources do I have?" or "show me my Azure resources"
  • List web apps, websites, or App Services

⚠️ Warning: App Service / Web Apps have no dedicated MCP list command. Prompts like "list websites", "list web apps", or "list app services" must route through this skill to use Azure Resource Graph.

💡 Tip: For single-resource-type queries, first check if a dedicated MCP tool can handle it (see routing table below). If none exists, use Azure Resource Graph.

Workflow

Step 1: Check for a Dedicated MCP Tool

For single-resource-type queries, check if a dedicated MCP tool can handle it:

Resource TypeMCP ToolCoverage
Virtual Machinescompute✅ Full — list, details, sizes
Storage Accountsstorage✅ Full — accounts, blobs, tables
Cosmos DBcosmos✅ Full — accounts, databases, queries
Key Vaultkeyvault⚠️ Partial — secrets/keys only, no vault listing
SQL Databasessql⚠️ Partial — requires resource group name
Container Registriesacr✅ Full — list registries
Kubernetes (AKS)aks✅ Full — clusters, node pools
App Service / Web Appsappservice❌ No list command — use ARG
Container Apps❌ No MCP tool — use ARG
Event Hubseventhubs✅ Full — namespaces, hubs
Service Busservicebus✅ Full — queues, topics

If a dedicated tool is available with full coverage, use it. Otherwise proceed to Step 2.

Step 2: Generate the ARG Query

Use extension_cli_generate to build the az graph query command:

mcp_azure_mcp_extension_cli_generate
  intent: "query Azure Resource Graph to <user's request>"
  cli-type: "az"

See Azure Resource Graph Query Patterns for common KQL patterns.

Step 3: Execute and Format Results

Run the generated command. Use --query (JMESPath) to shape output:

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

Use --first N to limit results. Use --subscriptions to scope.

Error Handling

ErrorCauseFix
resource-graph extension not foundExtension not installedaz extension add --name resource-graph
AuthorizationFailedNo read access to subscriptionCheck RBAC — need Reader role
BadRequest on queryInvalid KQL syntaxVerify table/column names; use =~ for case-insensitive type matching
Empty resultsNo matching resources or wrong scopeCheck --subscriptions flag; verify resource type spelling

Constraints

  • Always use =~ for case-insensitive type matching (types are lowercase)
  • Always scope queries with --subscriptions or --first for large tenants
  • Prefer dedicated MCP tools for single-resource-type queries
  • Never use ARG for real-time monitoring (data has slight delay)
  • Never attempt mutations through ARG (read-only)
