Implementation Reference

• src/index.ts:184-218 (handler)

  The handler for the 'delete_task' tool. It extracts the task_id from arguments, checks if the task exists and has no dependent tasks, deletes the task from the tasks object, saves the changes to the JSON file, and returns a confirmation message.

  case "delete_task": {
    const { task_id } = request.params.arguments as {
      task_id: string;
    };
  
    debug(`Deleting task ${task_id}`);
  
    const task = tasks[task_id];
    if (!task) {
      throw new McpError(ErrorCode.InvalidRequest, `Task ${task_id} not found`);
    }
  
    // Check if any other tasks depend on this one
    const dependentTasks = Object.values(tasks).filter(t => 
      t.dependencies?.includes(task_id)
    );
  
    if (dependentTasks.length > 0) {
      throw new McpError(
        ErrorCode.InvalidRequest, 
        `Cannot delete task ${task_id} as it has dependent tasks: ${dependentTasks.map(t => t.id).join(', ')}`
      );
    }
  
    delete tasks[task_id];
    saveTasks();
    debug(`Deleted task ${task_id}`);
  
    return {
      content: [{
        type: "text",
        text: JSON.stringify({ deleted: task_id }, null, 2)
      }]
    };
  }

• src/index.ts:388-401 (registration)

  Registration of the 'delete_task' tool in the ListToolsRequestSchema handler, providing the tool's name, description, and input schema for discovery by MCP clients.

  {
    name: "delete_task",
    description: "Delete a task if it has no dependents",
    inputSchema: {
      type: "object",
      properties: {
        task_id: {
          type: "string",
          description: "ID of the task to delete"
        }
      },
      required: ["task_id"]
    }
  },

• src/index.ts:391-400 (schema)

  The input schema for the 'delete_task' tool, defining the required 'task_id' parameter.

  inputSchema: {
    type: "object",
    properties: {
      task_id: {
        type: "string",
        description: "ID of the task to delete"
      }
    },
    required: ["task_id"]
  }
