## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `MICROSOFT_TODO_COMPLETE_TASK` | Complete Task | Mark a Microsoft To Do task as completed. Convenience wrapper that always PATCHes status='completed'; the server auto-sets completedDateTime. Use Update Task to reopen a task (status='notStarted') or to change other fields. |
| `MICROSOFT_TODO_CREATE_CHECKLIST_ITEM` | Create Checklist Item | Add a checklist item (subtask) to a Microsoft To Do task. Only display_name is required; the created item is returned with a GUID id, displayName, isChecked, and createdDateTime. |
| `MICROSOFT_TODO_CREATE_TASK` | Create Task | Create a task in a Microsoft To Do task list. Only title is required. Dates are passed as flat ISO-8601 strings plus a shared timezone; the tool builds the Graph dateTimeTimeZone objects. Notes are passed as body_content (+ body_content_type). NOTE: To Do treats due dates as whole days — the time component of due_date_time is normalized to midnight on save. |
| `MICROSOFT_TODO_CREATE_TASK_LIST` | Create Task List | Create a new Microsoft To Do task list. |
| `MICROSOFT_TODO_DELETE_CHECKLIST_ITEM` | Delete Checklist Item | Delete a checklist item (subtask) from a Microsoft To Do task. This permanently removes the checklist item (this cannot be undone). |
| `MICROSOFT_TODO_DELETE_TASK` | Delete Task | Delete a task from a Microsoft To Do task list. WARNING: this also permanently removes the task's checklist items and linked resources. |
| `MICROSOFT_TODO_DELETE_TASK_ATTACHMENT` | Delete Task Attachment | Permanently delete a file attachment from a Microsoft To Do task. This cannot be undone. |
| `MICROSOFT_TODO_DELETE_TASK_LIST` | Delete Task List | Delete a Microsoft To Do task list. WARNING: this cascades — all tasks in the list and their checklist items are permanently deleted. |
| `MICROSOFT_TODO_DOWNLOAD_TASK_ATTACHMENT` | Download Task Attachment | Download one file attached to a Microsoft To Do task. The file is offloaded to storage and returned as a downloadable reference rather than inline base64. |
| `MICROSOFT_TODO_GET_CHECKLIST_ITEM` | Get Checklist Item | Get a single Microsoft To Do checklist item (subtask) by its id, within a task in a task list. |
| `MICROSOFT_TODO_GET_CURRENT_USER` | Get Current User | Return the profile of the Microsoft account connected to this toolkit (whoami / connection verification). Useful to confirm which mailbox the To Do tasks belong to before other operations. |
| `MICROSOFT_TODO_GET_TASK` | Get Task | Get a single Microsoft To Do task by its id, within a task list. Set include_checklist_items=true to expand its checklist items inline. |
| `MICROSOFT_TODO_GET_TASK_ATTACHMENT` | Get Task Attachment | Get metadata for one file attached to a Microsoft To Do task. Use Download Task Attachment to retrieve the file contents. |
| `MICROSOFT_TODO_GET_TASK_LIST` | Get Task List | Get a single Microsoft To Do task list by its id. |
| `MICROSOFT_TODO_LIST_CHECKLIST_ITEMS` | List Checklist Items | List the checklist items (subtasks) of a To Do task. Auto-paginates so all subtasks are returned at once as {items: [...]}. |
| `MICROSOFT_TODO_LIST_TASK_ATTACHMENTS` | List Task Attachments | List the files attached to a Microsoft To Do task. Returns attachment metadata without file contents, one page at a time, plus a next_cursor. |
| `MICROSOFT_TODO_LIST_TASK_LISTS` | List Task Lists | List the To Do task lists owned by the connected user. The built-in default list has wellknown_list_name='defaultList'; user-created lists have wellknown_list_name='none'. Always returns at least the default list. Select the default list by id or wellknown_list_name, never by the localized display_name. |
| `MICROSOFT_TODO_LIST_TASKS` | List Tasks | List the tasks in a To Do task list. Checklist items (subtasks) are NOT returned by default; set include_checklist_items=true to expand them inline. Returns one page of tasks plus a next_cursor for the next page. |
| `MICROSOFT_TODO_UPDATE_CHECKLIST_ITEM` | Update Checklist Item | Update a checklist item (subtask) of a Microsoft To Do task: rename it (display_name) and/or check/uncheck it (is_checked). Partial update: only the fields you pass are changed; at least one is required. Setting is_checked=true marks the subtask done. |
| `MICROSOFT_TODO_UPDATE_TASK` | Update Task | Update fields of an existing Microsoft To Do task (title, notes, importance, status, due/start/reminder dates, categories). Partial update: only the fields you pass are changed; unset fields are left untouched. To mark a task done set status='completed' (or use the dedicated Complete Task tool). |
| `MICROSOFT_TODO_UPDATE_TASK_LIST` | Update Task List | Rename a Microsoft To Do task list (updates its displayName). |
| `MICROSOFT_TODO_UPLOAD_TASK_ATTACHMENT` | Upload Task Attachment | Attach a file up to 25 MB to a Microsoft To Do task. The tool automatically uses a single request for files under 3 MB and a chunked upload session for larger files. |

#### Path 1, Step 1: Install Composio

Install the Composio SDK
```python
pip install composio_openai
```

```typescript
npm install @composio/openai
```

#### Path 1, Step 2: Initialize Composio and Create Tool Router Session

session = composio.create(user_id='your-user-id')
```

```typescript
import OpenAI from 'openai';
import { Composio } from '@composio/core';
import { OpenAIResponsesProvider } from '@composio/openai';

const composio = new Composio({
  provider: new OpenAIResponsesProvider(),
});
const openai = new OpenAI({});
const session = await composio.create('your-user-id');
```

#### Path 1, Step 3: Execute Microsoft To Do Tools via Tool Router with Your Agent

Get tools from Tool Router session and execute Microsoft To Do actions with your Agent
```python
tools = session.tools
response = openai.responses.create(
  model='gpt-4.1',
  tools=tools,
  input=[{
    'role': 'user',
    'content': 'Create a Microsoft To Do task named Submit expense report in my Tasks list due tomorrow'
  }]
)
result = composio.provider.handle_tool_calls(
  response=response,
  user_id='your-user-id'
)
print(result)
```

```typescript
const tools = session.tools;
const response = await openai.responses.create({
  model: 'gpt-4.1',
  tools: tools,
  input: [{
    role: 'user',
    content: 'Create a Microsoft To Do task named Submit expense report in my Tasks list due tomorrow'
  }],
});
const result = await composio.provider.handleToolCalls(
  'your-user-id',
  response.output
);
console.log(result);
```

### Path 2: MCP Server Setup

#### Path 2, Step 1: Install Composio

Install the Composio SDK for Python or TypeScript
```python
pip install composio claude-agent-sdk
```

```typescript
npm install @composio/core ai @ai-sdk/openai @ai-sdk/mcp
```

#### Path 2, Step 2: Initialize Client and Create Tool Router Session

Import and initialize the Composio client, then create a Tool Router session for Microsoft To Do
```python
from composio import Composio
from claude_agent_sdk import ClaudeSDKClient, ClaudeAgentOptions

composio = Composio(api_key='your-composio-api-key')
session = composio.create(user_id='your-user-id')

```

```typescript
import { Composio } from '@composio/core';

const composio = new Composio({ apiKey: 'your-api-key' });
const session = await composio.create('your-user-id');
console.log(`Tool Router session created: ${session.mcp.url}`);
```

#### Path 2, Step 3: Connect to AI Agent

Use the MCP server with your AI agent (Anthropic Claude or Mastra)
```python
import asyncio

options = ClaudeAgentOptions(
    permission_mode='bypassPermissions',
    mcp_servers={
        'tool_router': {
            'type': 'http',
            'url': url,
            'headers': {
                'x-api-key': 'your-composio-api-key'
            }
        }
    },
    system_prompt='You are a helpful assistant with access to Microsoft To Do tools.',
    max_turns=10
)

async def main():
    async with ClaudeSDKClient(options=options) as client:
        await client.query('List overdue Microsoft To Do tasks from all my task lists')
        async for message in client.receive_response():
            if hasattr(message, 'content'):
                for block in message.content:
                    if hasattr(block, 'text'):
                        print(block.text)

asyncio.run(main())
```

```typescript
import { openai } from '@ai-sdk/openai';
import { experimental_createMCPClient as createMCPClient } from '@ai-sdk/mcp';
import { generateText } from 'ai';

const client = await createMCPClient({
  transport: {
    type: 'http',
    url: session.mcp.url,
    headers: {
      'x-api-key': 'your-composio-api-key',
