- server.js:2142-2151 (handler)The handler logic for the 'helm-upgrade' tool. It constructs a 'helm upgrade' command using the provided release name, chart, namespace, and values, executes it via execAsync, and returns the stdout or a success message.
case "helm-upgrade": { const { name, chart, namespace, values } = args; const nsArg = namespace ? `-n ${namespace}` : ""; const valuesArg = values ? `-f <(echo '${values}')` : ""; const cmd = `helm upgrade ${name} ${chart} ${nsArg} ${valuesArg}`; const { stdout } = await execAsync(cmd); return { content: [{ type: "text", text: stdout || `Helm release ${name} upgraded` }] }; } - server.js:1208-1233 (registration)The tool registration entry in the 'tools' array, including name, description, and inputSchema which defines the parameters for the helm-upgrade tool.
