The Struggle of Merging Cloud Bills

Today, figuring out cloud spend means a nightmare. You're staring at three separate dashboards: the AWS cost report, the Azure export file, and your internal K8s usage dashboard. Then you have to copy-paste data from one into a spreadsheet, trying to find matching resource IDs and dates so you can even start reconciling which bill paid for what actual workload.

With this MCP, that entire process disappears. You talk to your agent like talking to a teammate, asking it to compare the cost allocation of your 'production' namespace against the official cloud provider billing report. It handles the cross-referencing instantly and gives you the answer—no spreadsheets required.

Get Full Visibility with OpenCost (K8s Cost) MCP

You no longer have to manually query costs for specific assets or run separate reports for every external tool. The agent can consolidate everything: it checks the backing cost data using `get_assets`, pulls billing details via `get_cloud_cost`, and sums up third-party overhead with a single prompt.

What's different is that you get deep, actionable insights without ever leaving your conversational workflow. It turns complex financial auditing into simple conversation.

What OpenCost (K8s Cost) MCP does for your AI

OpenCost lets you talk to your infrastructure budget. Instead of diving through confusing dashboards and merging multiple billing spreadsheets, you just ask your AI agent questions about your Kubernetes costs in plain English. You can find out which specific namespace or controller is chewing up the most resources, or see how much compute power on a physical Node cost this month.

It pulls together data from core cloud provider bills—like AWS CUR or Azure exports—and cross-references it with internal workload allocations. This means you don't just get a total number; you get visibility into exactly why that number is what it is, helping your team maintain budget discipline while developing and running services.

When you connect this MCP via the Vinkius catalog, your agent gains access to all these cost metrics in one place.

Frequently asked questions about OpenCost (K8s Cost) MCP

How does OpenCost (K8s Cost) MCP handle multiple cloud providers? +

The MCP uses the get_cloud_cost tool to connect directly to various provider billing reports, including AWS CUR, Azure Export, and GCP Billing data. This means you can reconcile costs across different clouds from one place.

Can OpenCost (K8s Cost) MCP tell me which service is the most expensive? +

Yes. You can use get_allocation to query costs and resources allocated to specific namespaces, pods, or controllers to pinpoint your biggest spending areas.

What if I need cost data for services like Datadog? +

The MCP supports this via third-party tools. You use get_custom_cost_timeseries and get_custom_cost_total to track external service expenses over time or get a summary total.

Is OpenCost (K8s Cost) MCP only for AWS? +

No. It is designed to be cloud-agnostic, pulling data from multiple sources including Azure and GCP in addition to AWS billing reports.

How do I check the cost of a physical node using OpenCost (K8s Cost) MCP? +

Use the get_assets tool. This retrieves backing cost data broken down by individual assets, giving you visibility into nodes, disks, and load balancers.
