Implementation Reference

• src/todo-index.ts:675-795 (handler)

  Handler function that authenticates with Microsoft Graph, constructs the API URL with optional OData query parameters (filter, select, orderby, top, skip, count), fetches tasks from /me/todo/lists/{listId}/tasks, formats each task with ID, title, status indicator, due date, importance, categories, and description preview, and returns formatted text response with optional total count.
  async ({ listId, filter, select, orderby, top, skip, count }) => { try { const token = await getAccessToken(); if (!token) { return { content: [ { type: "text", text: "Failed to authenticate with Microsoft API", }, ], }; } // Build the query parameters const queryParams = new URLSearchParams(); if (filter) queryParams.append('$filter', filter); if (select) queryParams.append('$select', select); if (orderby) queryParams.append('$orderby', orderby); if (top !== undefined) queryParams.append('$top', top.toString()); if (skip !== undefined) queryParams.append('$skip', skip.toString()); if (count !== undefined) queryParams.append('$count', count.toString()); // Construct the URL with query parameters const queryString = queryParams.toString(); const url = `${MS_GRAPH_BASE}/me/todo/lists/${listId}/tasks${queryString ? '?' + queryString : ''}`; console.error(`Making request to: ${url}`); const response = await makeGraphRequest<{ value: Task[], '@odata.count'?: number }>( url, token ); if (!response) { return { content: [ { type: "text", text: `Failed to retrieve tasks for list: ${listId}`, }, ], }; } const tasks = response.value || []; if (tasks.length === 0) { return { content: [ { type: "text", text: `No tasks found in list with ID: ${listId}`, }, ], }; } // Format the tasks based on available properties const formattedTasks = tasks.map((task) => { // Default format let taskInfo = `ID: ${task.id}\nTitle: ${task.title}`; // Add status if available if (task.status) { const status = task.status === "completed" ? "✓" : "○"; taskInfo = `${status} ${taskInfo}`; } // Add due date if available if (task.dueDateTime) { taskInfo += `\nDue: ${new Date(task.dueDateTime.dateTime).toLocaleDateString()}`; } // Add importance if available if (task.importance) { taskInfo += `\nImportance: ${task.importance}`; } // Add categories if available if (task.categories && task.categories.length > 0) { taskInfo += `\nCategories: ${task.categories.join(', ')}`; } // Add body content if available and not empty if (task.body && task.body.content && task.body.content.trim() !== '') { const previewLength = 50; const contentPreview = task.body.content.length > previewLength ? task.body.content.substring(0, previewLength) + '...' : task.body.content; taskInfo += `\nDescription: ${contentPreview}`; } return `${taskInfo}\n---`; }); // Add count information if requested and available let countInfo = ''; if (count && response['@odata.count'] !== undefined) { countInfo = `Total count: ${response['@odata.count']}\n\n`; } return { content: [ { type: "text", text: `Tasks in list ${listId}:\n\n${countInfo}${formattedTasks.join("\n")}`, }, ], }; } catch (error) { return { content: [ { type: "text", text: `Error fetching tasks: ${error}`, }, ], }; } }
• src/todo-index.ts:666-674 (schema)

  Zod input schema defining parameters for the get-tasks tool: required listId, optional OData filter, select, orderby, top, skip, and count.
  { listId: z.string().describe("ID of the task list"), filter: z.string().optional().describe("OData $filter query (e.g., 'status eq \\'completed\\'')"), select: z.string().optional().describe("Comma-separated list of properties to include (e.g., 'id,title,status')"), orderby: z.string().optional().describe("Property to sort by (e.g., 'createdDateTime desc')"), top: z.number().optional().describe("Maximum number of tasks to retrieve"), skip: z.number().optional().describe("Number of tasks to skip"), count: z.boolean().optional().describe("Whether to include a count of tasks") },
• src/todo-index.ts:663-796 (registration)

  Registration of the get-tasks tool on the MCP server using server.tool(), specifying name, description, input schema, and inline handler function.
