# Azure Resource Lookup 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**" > 💡 **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. ## Quick Reference | Property | Value | |----------|-------| | **Query Language** | KQL (Kusto Query Language subset) | | **CLI Command** | `az graph query -q "<KQL>" -o table` | | **Extension** | `az extension add --name resource-graph` | | **MCP Tool** | `extension_cli_generate` with intent for `az graph query` | | **Best For** | Cross-subscription queries, orphaned resources, tag audits | ## MCP Tools | Tool | Purpose | When to Use | |------|---------|-------------| | `extension_cli_generate` | Generate `az graph query` commands | Primary tool — generate ARG queries from user intent | | `mcp_azure_mcp_subscription_list` | List available subscriptions | Discover subscription scope before querying | | `mcp_azure_mcp_group_list` | List resource groups | Narrow query scope | ## Workflow ### Step 1: Check for a Dedicated MCP Tool For single-resource-type queries, check if a dedicated MCP tool can handle it: | Resource Type | MCP Tool | Coverage | |---|---|---| | Virtual Machines | `compute` | ✅ Full — list, details, sizes | | Storage Accounts | `storage` | ✅ Full — accounts, blobs, tables | | Cosmos DB | `cosmos` | ✅ Full — accounts, databases, queries | | Key Vault | `keyvault` | ⚠️ Partial — secrets/keys only, no vault listing | | SQL Databases | `sql` | ⚠️ Partial — requires resource group name | | Container Registries | `acr` | ✅ Full — list registries | | Kubernetes (AKS) | `aks` | ✅ Full — clusters, node pools | | App Service / Web Apps | `appservice` | ❌ No list command — use ARG | | Container Apps | — | ❌ No MCP tool — use ARG | | Event Hubs | `eventhubs` | ✅ Full — namespaces, hubs | | Service Bus | `servicebus` | ✅ 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: ```yaml 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: ```bash 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 | Error | Cause | Fix | |-------|-------|-----| | `resource-graph extension not found` | Extension not installed | `az extension add --name resource-graph` | | `AuthorizationFailed` | No read access to subscription | Check RBAC — need Reader role | | `BadRequest` on query | Invalid KQL syntax | Verify table/column names; use `=~` for case-insensitive type matching | | Empty results | No matching resources or wrong scope | Check `--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)
