What it does

Automatically connects to an Azure subscription using OAuth2 Service Principal authentication to retrieve all cloud resources. It queries the Resource Graph API for resource details and the Cost Management API for spending data, then merges these datasets. The agent generates formatted reports including total spending, top expensive resources, and cost breakdowns by type.

How hands-off: Assists you, you do the final step
Setup: An afternoon · about an afternoon
Works with: n8n, Azure Resource Graph API, Cost Management API, Code

Tools that fit

Services

n8n : Workflow orchestration and automation platform

Code : Data processing and merging resources with costs

api

Azure Resource Graph API : Querying Azure subscription resources

Cost Management API : Fetching cost and usage data

Watch out for

The Resource Graph API has a limit of 1000 resources per query so you must implement pagination to capture all assets in large subscriptions.
Cost Management data can have a latency of up to two days so the report should clearly state the date range and potential staleness.
Service Principal secrets expire automatically so add an alerting mechanism or token refresh logic to prevent authentication failures during scheduled runs.
Merging large datasets in n8n Code nodes can cause memory timeouts so process data in chunks or filter resources before merging.
