Before you connect
Questions about OpenCost.
The practical details behind the request, access and result.
What is the OpenCost (K8s Cost) MCP for?
It lets your AI agent pull and analyze Kubernetes cost data from your OpenCost instance. You can ask questions about your spending, workload costs, and cloud billing instead of digging through complex dashboards.
Can I use OpenCost (K8s Cost) to see my AWS bills?
Yes, it can pull data from AWS CUR, Azure Export, and GCP Billing reports. This helps you see how your K8s costs align with what your cloud provider is actually charging you.
Does the OpenCost (K8s Cost) MCP track third-party capabilities?
It can track costs for external services like Datadog or MongoDB Atlas. You can get total summaries or see how those costs change over time.
How do I get my Kubernetes spend into my AI agent?
You connect this Connector to your AI client and provide your OpenCost API URL. From there, you can just type questions about your budget or resource usage.
Can I use OpenCost (K8s Cost) to see costs for specific pods?
Yes, the Connector can query costs and resources for specific workloads. This helps you identify which specific pods or controllers are burning through your budget.
Is OpenCost (K8s Cost) good for FinOps?
It's a primary capability for FinOps teams because it bridges the gap between internal K8s labels and external cloud billing. It makes reconciling those two numbers much faster.
Can I see costs grouped by a specific Kubernetes namespace?
Yes. Use the get_allocation capability and set the aggregate parameter to 'namespace'. You can also specify a window like '7d' to see trends over the last week.
Does this server support viewing external cloud provider billing?
Absolutely. The get_cloud_cost capability retrieves data directly from cloud provider billing reports (AWS CUR, Azure Export, GCP Billing) to give you a complete financial picture.
Can I track costs for non-Kubernetes services like Datadog?
Yes, if configured in your OpenCost instance, you can use get_custom_cost_total or get_custom_cost_timeseries to query costs for third-party SaaS and infrastructure services.
