Implementation Reference

• server.js:1692-1700 (handler)

  Handler function for the 'rollout-history' tool. Executes 'kubectl rollout history deployment/{deployment}' with optional namespace and returns the stdout as text content.

  case "rollout-history": {
    const { deployment, namespace } = args;
    const nsArg = namespace ? `-n ${namespace}` : "";
    const cmd = `kubectl rollout history deployment/${deployment} ${nsArg}`;
    const { stdout } = await execAsync(cmd);
    return {
      content: [{ type: "text", text: stdout || "No rollout history found" }]
    };
  }

• server.js:462-478 (schema)

  Input schema and tool registration definition for 'rollout-history' in the tools list returned by ListToolsRequestHandler.

    name: "rollout-history",
    description: "Show the rollout history of a deployment",
    inputSchema: {
      type: "object",
      properties: {
        deployment: { 
          type: "string",
          description: "The name of the deployment to check history for"
        },
        namespace: { 
          type: "string",
          description: "The namespace of the deployment (optional, defaults to current context namespace)"
        }
      },
      required: ["deployment"]
    }
  },

• server.js:1392-1394 (registration)
