- src/tools/values.ts:19-52 (handler)Handler function that fetches the Helm chart's values.yaml from Artifact Hub by first getting chart info, determining version, retrieving values, and returning as text content or error message.
async ({ chartRepo, chartName, version }: ValuesParams) => { try { let packageId: string; let chartVersion: string; // First get the chart info const chartInfo = await getChartInfo(chartRepo, chartName); packageId = chartInfo.package_id; // If version is not provided, use the latest version chartVersion = version || chartInfo.version; // Get the values.yaml const valuesYaml = await getChartValues(packageId, chartVersion); return { content: [ { type: "text", text: valuesYaml, }, ], }; } catch (error) { return { content: [ { type: "text", text: `Error retrieving values.yaml: ${(error as Error).message}`, }, ], }; } } - src/tools/values.ts:11-18 (schema)Zod input schema defining parameters: chartRepo (string), chartName (string), version (optional string).
{ chartRepo: z.string().describe("The Helm chart repository name"), chartName: z.string().describe("The Helm chart name"), version: z .string() .optional() .describe("The chart version (optional, defaults to latest)"), }, - src/tools/values.ts:7-54 (registration)Function that registers the 'helm-chart-values' tool with the MCP server, specifying name, description, input schema, and handler.
export function registerValuesTool(server: McpServer) { return server.tool( "helm-chart-values", "Get the values.yaml file for a specific Helm chart from Artifact Hub", { chartRepo: z.string().describe("The Helm chart repository name"), chartName: z.string().describe("The Helm chart name"), version: z .string() .optional() .describe("The chart version (optional, defaults to latest)"), }, async ({ chartRepo, chartName, version }: ValuesParams) => { try { let packageId: string; let chartVersion: string; // First get the chart info const chartInfo = await getChartInfo(chartRepo, chartName); packageId = chartInfo.package_id; // If version is not provided, use the latest version chartVersion = version || chartInfo.version; // Get the values.yaml const valuesYaml = await getChartValues(packageId, chartVersion); return { content: [ { type: "text", text: valuesYaml, }, ], }; } catch (error) { return { content: [ { type: "text", text: `Error retrieving values.yaml: ${(error as Error).message}`, }, ], }; } } ); } - src/index.ts:18-18 (registration)Invokes registerValuesTool to add the tool to the main MCP server instance.
