What is Kubeopt?
Kubeopt is the MCP server component of KubeOpt, a Kubernetes cost engineering tool. It exposes six tools over stdio transport, allowing AI assistants like Claude Desktop, Cursor, and Windsurf to query cluster cost data, optimization recommendations, and trigger fresh analyses from a running KubeOpt instance.
How to use Kubeopt?
Run KubeOpt locally (python main.py) or deploy it, then configure your MCP client to execute the server script (python -m mcp_server.server) with the environment variables KUBEOPT_API_URL, KUBEOPT_USERNAME, and KUBEOPT_PASSWORD. After restarting the client, ask questions in plain English about Kubernetes costs.
Key features of Kubeopt
- Six MCP tools for querying cost and cluster data
- Connects to Azure AKS, AWS EKS, and Google GKE
- Runs 16 optimization algorithms (rightsizing, HPA, storage, etc.)
- Generates actionable implementation plans with kubectl commands
- Provides per-pod cost breakdowns filterable by namespace
- Supports on-demand fresh analyses with polling
Use cases of Kubeopt
- Query top cost savings opportunities across all clusters
- Identify the most expensive pods in a specific namespace
- Get a summary of total Kubernetes spend for the current month
- Check optimization scores for a staging cluster
- Trigger a fresh analysis on a specific cluster and receive results
