Overview

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.
