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.

Why OpenAI Agents SDK?
The OpenAI Agents SDK auto-discovers all 6 tools from OpenCost (K8s Cost) through native MCP integration. Build agents with built-in guardrails, tracing, and handoff patterns. chain multiple agents where one queries OpenCost (K8s Cost), another analyzes results, and a third generates reports, all orchestrated through Vinkius.

Why teams choose Vinkius for OpenCost (K8s Cost) in OpenAI Agents SDK
The OpenCost (K8s Cost) MCP Server runs on Vinkius-managed infrastructure inside AWS — a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts. All 6 tools execute in hardened sandboxes optimized for native MCP execution.
Your AI agents in OpenAI Agents SDK only access the data you authorize, with DLP that blocks sensitive information from ever reaching the model, kill switch for instant shutdown, and up to 60% token savings. Enterprise-grade infrastructure, zero maintenance.
* Every MCP server runs on Vinkius-managed infrastructure inside AWS - a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts optimized for native MCP execution. See our infrastructure
How Vinkius secures
OpenCost (K8s Cost) for OpenAI Agents SDK
Every tool call from OpenAI Agents SDK to the OpenCost (K8s Cost) MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
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 the OpenAI Agents SDK connect to MCP?
Use MCPServerSse(url=...) to create a server connection. The SDK auto-discovers all tools and makes them available to your agent with full type information.
Can I use multiple MCP servers in one agent?
Yes. Pass a list of MCPServerSse instances to the agent constructor. The agent can use tools from all connected servers within a single run.
Does the SDK support streaming responses?
Yes. The SDK supports SSE and Streamable HTTP transports, both of which work natively with Vinkius.
