Implementation Reference
- src/tools/createIndexTemplate.ts:122-150 (handler)The actual handler function that executes the delete_index_template tool logic. It calls esClient.indices.deleteIndexTemplate with the provided name and returns a success/error message.
export async function deleteIndexTemplate( esClient: Client, name: string ) { try { const response = await esClient.indices.deleteIndexTemplate({ name }); return { content: [ { type: "text" as const, text: response.acknowledged ? `Index template "${name}" deleted successfully.` : `Index template delete request sent, but not acknowledged. Check cluster status.` } ] }; } catch (error) { console.error(`Delete index template failed: ${error instanceof Error ? error.message : String(error)}`); return { content: [ { type: "text" as const, text: `Error: ${error instanceof Error ? error.message : String(error)}` } ] }; - src/server.ts:276-290 (registration)Registers the 'delete_index_template' tool with the MCP server, defining the schema (name: zod string) and wiring it to the deleteIndexTemplate handler.
// Delete an index template server.tool( "delete_index_template", "Delete an Elasticsearch index template", { name: z .string() .trim() .min(1, "Template name is required") .describe("Name of the template to delete") }, async ({ name }) => { return await deleteIndexTemplate(esClient, name); } ); - src/server.ts:13-27 (helper)Import of the deleteIndexTemplate function from the tools module to be used in server registration.
import { createIndexTemplate, getIndexTemplate, deleteIndexTemplate } from "./tools/createIndexTemplate.js"; export { listIndices, getMappings, search, getClusterHealth, createIndex, createMapping, bulk, reindex, createIndexTemplate, getIndexTemplate, deleteIndexTemplate }; - src/server.ts:24-27 (helper)Re-export of deleteIndexTemplate alongside other tool functions for external use.
