Implementation Reference
- src/index.ts:824-863 (handler)Implements the core logic for the mark_task_undone tool: validates index, reads task data, sets checklist item done to false, updates progress by saving to file, returns success message.private async markTaskUndone(args: any): Promise<any> { if (args?.index === undefined) { throw new McpError(ErrorCode.InvalidParams, 'Index is required'); } try { const taskData = await this.readTaskData(); // Check if the index is valid if (args.index < 0 || args.index >= taskData.checklist.length) { throw new McpError(ErrorCode.InvalidParams, `Invalid index: ${args.index}`); } // Mark the checklist item as not done taskData.checklist[args.index].done = false; // Write the updated task data to the file await this.writeTaskData(taskData); return { content: [ { type: 'text', text: 'Task marked as not done.', }, ], }; } catch (error) { console.error('Error marking task as not done:', error); return { content: [ { type: 'text', text: `Error marking task as not done: ${error instanceof Error ? error.message : String(error)}`, }, ], isError: true, }; } }
- src/index.ts:278-290 (schema)Defines the input schema for the mark_task_undone tool in the ListTools response, specifying required 'index' parameter.{ name: 'mark_task_undone', description: 'Marks a checklist item as not done.', inputSchema: { type: 'object', properties: { index: { type: 'number', description: 'The index of the checklist item to mark as not done (0-based)' } }, required: ['index'] }
- src/index.ts:436-437 (registration)Registers the tool handler in the CallToolRequest switch statement, routing calls to the markTaskUndone method.case 'mark_task_undone': return await this.markTaskUndone(request.params.arguments);
