The Problem

Managing tasks through conversation requires:

  • OAuth complexity - Google’s authentication flow is non-trivial
  • API integration - Task lists and tasks are separate resources
  • State management - Sessions, tokens, and user context

AI agents needed a simple way to manage tasks without building custom integrations.

Solution

Built a complete MCP server for Google Tasks:

Full CRUD

Complete task management - create lists, add tasks, update, complete, delete. All through natural language.

What’s Included

  • Task Lists - Create, list, update, delete task lists
  • Tasks - Full task management with due dates and notes
  • Completion Tracking - Mark tasks complete or incomplete
  • OAuth Flow - Secure Google authentication
