Azure SKU scout — explore availability zones, capacity, pricing, and plan VM deployments across subscriptions

Azure Scout: az-scout

Scout Azure regions for VM availability, zone mappings, pricing, spot scores, and quota — then plan deployments with confidence.

📖 Full documentation: docs.az-scout.com

az-scout helps Azure operators and architects answer the questions that matter when planning resilient, cost-efficient VM deployments:

• Do my subscriptions share the same physical datacenter for logical zone 1?
• Which VM SKUs are available in all three zones with headroom in my quota?
• What is the Spot placement likelihood for this SKU family right now?
• Which deployment plan gives me the best confidence score across zones?

All from a single web UI — or through an MCP-powered AI agent connected to your favourite tools (Claude, VS Code Copilot, etc.).

Quick start

Prerequisites

Requirement	Details
Python	≥ 3.11
Azure credentials	Any method supported by DefaultAzureCredential (az login, managed identity, …)
RBAC	Reader on the subscriptions you want to query, Virtual Machine Contributor on the subscriptions for Spot Placement Scores retrieval
Azure OpenAI (optional)	For the AI Chat Assistant: set AZURE_OPENAI_ENDPOINT, AZURE_OPENAI_API_KEY, AZURE_OPENAI_DEPLOYMENT, and optionally AZURE_OPENAI_API_VERSION

Run locally with uv tool (recommended)

# Make sure you are authenticated to Azure
az login

# Run the tool (no install required)
uvx az-scout

Your browser opens automatically at http://127.0.0.1:5001.

Plugins

az-scout can be extended with pip-installable plugins discovered automatically at startup. See docs/PLUGINS.md for the plugin development guide and the scaffold for a ready-to-use template.

A Plugin Manager is included in the UI to browse the online plugin catalog, install, update, and remove plugins.

Installation options

Recommended: install az-scout with uv

uv install az-scout
uvx az-scout

Alternative: install az-scout with pip

pip install az-scout
az-scout

Docker

docker run --rm -p 8000:8000 \
  -e AZURE_TENANT_ID=<your-tenant> \
  -e AZURE_CLIENT_ID=<your-sp-client-id> \
  -e AZURE_CLIENT_SECRET=<your-sp-secret> \
  ghcr.io/az-scout/az-scout:latest

Dev Container

A Dev Container configuration is included for a one-click development environment. Requires Docker and VS Code with the Dev Containers extension.

Open the repo in VS Code → Reopen in Container → run uv run az-scout web --host 0.0.0.0 --port 5001 --reload --no-open -v.

Azure Container App

It is also possible to deploy az-scout as a web app in Azure using the provided Bicep template (see Deploy to Azure section below).

Note: The web UI is designed for local use and may not be suitable for public-facing deployment without additional security measures (authentication, network restrictions, etc.). The MCP server can be exposed over the public internet if needed, but ensure you have proper authentication and authorization in place to protect access to Azure data.

UI guided deployment

A Bicep template is provided to deploy az-scout as an Azure Container App with a managed identity. You can use the Deploy to Azure button above for a portal-guided experience, or use the CLI commands below.

Resources created

The deployment creates:

Resource	Purpose
Container App	Runs ghcr.io/az-scout/az-scout
Managed Identity	Reader role on target subscriptions
VM Contributor	Virtual Machine Contributor role for Spot Placement Scores (enabled by default)
Log Analytics	Container logs and diagnostics
Container Apps Env	Hosting environment

Note: The Virtual Machine Contributor role is required for querying Spot Placement Scores (POST endpoint). Set enableSpotScoreRole=false to skip this if you don't need spot scores or prefer to manage permissions manually.

Usage

CLI options

az-scout [COMMAND] [OPTIONS]

az-scout --help.     # show global help

  --host TEXT     Host to bind to.  [default: 127.0.0.1]
  --port INTEGER  Port to listen on.  [default: 5001]
  --no-open       Don't open the browser automatically.
  -v, --verbose   Enable verbose logging.
  --reload        Auto-reload on code changes (development only).
  --help          Show this message and exit.

az-scout mcp

Run the MCP server.

  --http          Use Streamable HTTP transport instead of stdio.
  --port INTEGER  Port for Streamable HTTP transport.  [default: 8080]
  -v, --verbose   Enable verbose logging.
  --help          Show this message and exit.

az-scout chat

Interactive AI chat in the terminal. Requires Azure OpenAI credentials.

# Start an interactive session
az-scout chat

# One-shot query
az-scout chat "What SKUs are available in francecentral?"

  -v, --verbose   Enable verbose logging.
  --help          Show this message and exit.

Slash commands are available during the chat session:

Command	Description
/help	Show available commands
/context	Show current tenant, subscription, region, and mode
/tenant [id]	Switch tenant (interactive picker or direct)
/subscription [id]	Switch subscription (interactive picker or direct)
/region [name]	Switch region (interactive picker or direct)
/mode [name]	Switch chat mode (discussion, planner, …)
/tenants	List accessible tenants
/subscriptions	List enabled subscriptions
/regions	List AZ-enabled regions
/clear	Clear conversation history
/new	Start a new session (re-select tenant, clear history)
/exit	Exit (or press Ctrl+D)

MCP server

An MCP server is included, allowing AI agents (Claude Desktop, VS Code Copilot, etc.) to query zone mappings and SKU availability directly.

Available tools

Tool	Description
list_tenants	Discover Azure AD tenants and authentication status
list_subscriptions	List enabled subscriptions (optionally scoped to a tenant)
list_regions	List regions that support Availability Zones
get_zone_mappings	Get logical→physical zone mappings for subscriptions in a region
get_sku_availability	Get VM SKU availability per zone with restrictions, capabilities, quota, and deployment confidence
get_spot_scores	Get Spot Placement Scores (High / Medium / Low) for a list of VM sizes in a region
get_sku_deployment_confidence	Compute Deployment Confidence Scores (0–100) for one or more VM SKUs with full signal breakdown
get_sku_pricing_detail	Get detailed Linux pricing (PayGo, Spot, RI 1Y/3Y, SP 1Y/3Y) and VM profile for a single SKU

Plugin tools: Plugins can register additional MCP tools. For example, the Strategy Advisor plugin adds a capacity_strategy tool.

API

API documentation is available at /docs (Swagger UI) and /redoc (ReDoc) when the server is running.
