Kubernetes MCP Server

Instructions

Implementation Reference

• server.js:1499-1505 (handler)

  The handler function for the 'list-pv' tool that runs the kubectl command to list all PersistentVolumes (PVs) in the cluster.

  case "list-pv": {
    const cmd = `kubectl get pv -o wide`;
    const { stdout } = await execAsync(cmd);
    return {
      content: [{ type: "text", text: stdout || "No persistent volumes found" }]
    };
  }

• server.js:141-148 (schema)

  The tool definition including name, description, and empty input schema (no parameters required). This is part of the tools array used for tool listing and validation.

  {
    name: "list-pv",
    description: "List Kubernetes persistent volumes",
    inputSchema: {
      type: "object",
      properties: {}
    }
  },

• server.js:1392-1394 (registration)

  Registers the listTools handler which returns the full tools array containing the 'list-pv' tool definition.

  server.setRequestHandler(ListToolsRequestSchema, async () => {
    return { tools };
  });
