Task API Server

Implementation Reference

• src/index.ts:523-548 (handler)

  The handler function that executes the deleteTask tool logic. It makes a DELETE API request to remove the specified task and returns success or error message.
  async ({ taskId }: { taskId: number }) => { try { const response = await makeApiRequest("DELETE", `/tasks/${taskId}`); logDebug(`Deleted task ID ${taskId}`); return { content: [ { type: "text", text: response.message || `Task ${taskId} deleted successfully.` } ] }; } catch (error: any) { logError(`Error in deleteTask: ${error.message}`); return { content: [ { type: "text", text: `Error deleting task: ${error.message}` } ] }; }
• src/http-server.ts:539-564 (handler)

  Identical handler function for the deleteTask tool in the HTTP server implementation.
  async ({ taskId }: { taskId: number }) => { try { const response = await makeApiRequest("DELETE", `/tasks/${taskId}`); logDebug(`Deleted task ID ${taskId}`); return { content: [ { type: "text", text: response.message || `Task ${taskId} deleted successfully.` } ] }; } catch (error: any) { logError(`Error in deleteTask: ${error.message}`); return { content: [ { type: "text", text: `Error deleting task: ${error.message}` } ] }; }
• src/index.ts:519-522 (schema)

  Zod input schema for the deleteTask tool, validating the taskId parameter.
  { taskId: z.number().int().positive("Task ID must be a positive integer") .describe("The unique ID of the task to delete") },
• src/index.ts:517-550 (registration)

  Registration of the deleteTask tool on the MCP server using server.tool().
  server.tool( "deleteTask", { taskId: z.number().int().positive("Task ID must be a positive integer") .describe("The unique ID of the task to delete") }, async ({ taskId }: { taskId: number }) => { try { const response = await makeApiRequest("DELETE", `/tasks/${taskId}`); logDebug(`Deleted task ID ${taskId}`); return { content: [ { type: "text", text: response.message || `Task ${taskId} deleted successfully.` } ] }; } catch (error: any) { logError(`Error in deleteTask: ${error.message}`); return { content: [ { type: "text", text: `Error deleting task: ${error.message}` } ] }; } } );
• src/index.ts:68-168 (helper)

  Shared helper function that performs all API calls to the backend task manager service, used by deleteTask and other tools for HTTP requests with authentication.
  async function makeApiRequest(method: string, endpoint: string, data: any = null, params: any = null): Promise<any> { const url = `${API_BASE_URL}${endpoint}`; // Validate that API_KEY is defined if (!API_KEY) { throw new Error("TASK_MANAGER_API_KEY environment variable is not defined.
