How to Set Up and Use Microsoft Todo
The Microsoft Todo MCP Server connects AI assistants to Microsoft To Do via the Microsoft Graph API, enabling natural language management of task lists, individual tasks, and checklist subtasks. It supports full CRUD operations on task lists and tasks, including due dates, importance flags, reminders, and categories. Users authenticate once via OAuth 2.0 with automatic token refresh, making it possible to ask Claude to create, update, complete, or organize tasks across all your Microsoft To Do lists without opening the app.
Prerequisites
- Node.js 16+ installed (tested on 18.x, 20.x, 22.x)
- A Microsoft account (work, school, or personal — note personal accounts have restricted Graph API access)
- An Azure app registration with Microsoft Graph Todo.ReadWrite permissions
- CLIENT_ID, CLIENT_SECRET, and TENANT_ID from your Azure app registration
- An MCP-compatible client such as Claude Desktop or Cursor
Register an Azure application
Go to portal.azure.com → Azure Active Directory → App Registrations → New Registration. Set the redirect URI to http://localhost:3000/callback. Under API Permissions, add Microsoft Graph → Delegated → Tasks.ReadWrite.
Install the MCP server package
Install the microsoft-todo-mcp-server package globally or use npx for one-off execution.
npm install -g microsoft-todo-mcp-server
# or run directly:
npx microsoft-todo-mcp-serverConfigure environment variables
Create a .env file in the package directory with your Azure app credentials. Use 'common' as TENANT_ID to support both personal and organizational accounts.
CLIENT_ID=your_azure_app_client_id
CLIENT_SECRET=your_azure_app_client_secret
TENANT_ID=organizations
REDIRECT_URI=http://localhost:3000/callbackAuthenticate via OAuth
Run the auth command to open a browser window for Microsoft OAuth login. This generates a tokens.json file with access and refresh tokens.
pnpm run auth
# or if installed globally:
npx microsoft-todo-mcp-server authConfigure Claude Desktop
Add the server to your Claude Desktop MCP configuration with your Azure credentials as environment variables.
{
"mcpServers": {
"microsoft-todo": {
"command": "npx",
"args": ["-y", "microsoft-todo-mcp-server"],
"env": {
"CLIENT_ID": "your_azure_client_id",
"CLIENT_SECRET": "your_azure_client_secret",
"TENANT_ID": "organizations",
"REDIRECT_URI": "http://localhost:3000/callback"
}
}
}
}Restart Claude Desktop and verify
Restart Claude Desktop and ask it to list your Microsoft To Do task lists. Successful output confirms authentication and connection are working.

Claude Desktop configuration with Azure OAuth credentials for Microsoft To Do access.

}
}
}
}Prompts to try
Once connected, manage your Microsoft To Do tasks directly through Claude.
- "Show me all my Microsoft To Do task lists"
- "Create a task called 'Review Q4 report' in my Work list, due this Friday, marked as important"
- "Mark all tasks in my Shopping list as completed"
- "Add a subtask 'Write introduction' to the task 'Draft blog post'"
- "Show me all incomplete high-priority tasks across all my lists"Troubleshooting Microsoft Todo
OAuth authentication fails or redirect URI mismatch error
Verify that the Redirect URI in your Azure app registration exactly matches http://localhost:3000/callback (including the path). Also ensure the REDIRECT_URI environment variable matches this value exactly — any difference will cause the OAuth flow to fail.
Tasks API returns 403 Forbidden for personal Microsoft accounts
Microsoft restricts Graph API access for personal accounts (outlook.com, hotmail.com, live.com). This is a known Microsoft limitation. Use a work or school account, or set TENANT_ID to 'consumers' and note that some operations may still be restricted.
Tokens expire and the server stops working
The server auto-refreshes tokens 5 minutes before expiry. If tokens become invalid, delete tokens.json and re-run the auth flow with 'pnpm run auth'. Ensure CLIENT_SECRET has not expired in your Azure app registration.
