What the OpenCost (K8s Cost) MCP Server unlocks
Connect your OpenCost instance to any AI agent to gain real-time visibility into your Kubernetes spending and infrastructure efficiency through natural language.
What you can do

get_allocation. - Asset Inspection — Retrieve backing cost data for physical infrastructure like Nodes, Disks, and Load Balancers via
get_assets. - Cloud Billing Integration — Access AWS CUR, Azure Export, and GCP Billing data directly with
get_cloud_costto reconcile K8s costs with provider bills. - Third-Party Costs — Track external service expenses (e.g., Datadog, MongoDB Atlas) using custom cost timeseries and total summary tools.
- Granular Filtering — Aggregate data by labels, annotations, or service levels to understand exactly where your budget is going.

Frequently asked questions about the OpenCost (K8s Cost) MCP Server
Can I see costs grouped by a specific Kubernetes namespace?
Yes. Use the get_allocation tool 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 tool 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.
