What is the OpenCost (K8s Cost) MCP Server?
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
- Workload Allocation — Query costs and resources allocated to clusters, nodes, namespaces, controllers, and pods using
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.
How it works
- Subscribe to this server
- Enter your OpenCost API Base URL
- Start auditing your cloud spend from Claude, Cursor, or any MCP client
Who is this for?
- DevOps & Platform Engineers — Identify expensive namespaces or orphaned resources without manual dashboard diving.
- FinOps Teams — Reconcile internal Kubernetes allocations with external cloud provider billing reports instantly.
- Engineering Managers — Get quick summaries of project-based costs to stay within budget during development cycles.

Frequently asked questions
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.
How does Cline connect to MCP servers?
Cline reads MCP server configurations from its settings panel in VS Code. Add the server URL and Cline discovers all available tools on initialization.
Can Cline run MCP tools without approval?
By default, Cline asks for confirmation before executing tool calls. You can configure auto-approval rules for trusted servers in the settings.
Does Cline support multiple MCP servers at once?
Yes. Configure as many servers as needed. Cline can use tools from different servers within the same autonomous task execution.
