Google Tasks MCP Server: Integrating AI Applications with Google Tasks

Overview: What is Google Tasks MCP Server?

The Google Tasks MCP (Model Context Protocol) Server is a specialized backend service that integrates with the Google Tasks API, allowing various AI applications to interact seamlessly with users' task lists. This server acts as a bridge between these applications and the rich functionality provided by Google Tasks. Whether you're working on an application like Claude Desktop, Continue, or Cursor, this MCP server simplifies the process of integrating tasks management into your AI workflow.

🔧 Core Features & MCP Capabilities

The core features of the Google Tasks MCP Server include:

1. Search for Specific Tasks: Users can search their task lists using specific queries.
2. List all Tasks: Retrieve a comprehensive list of all current tasks.
3. Create New Tasks: Enable users to create new entries in their task list with optional parameters like due date and notes.
4. Update Existing Tasks: Modify the details of existing tasks, including title, status, and due dates.
5. Delete Tasks: Remove tasks from the user’s Google Task list.
6. Clear Completed Tasks: Automatically remove completed tasks to keep the lists clean.

These capabilities are implemented within the Model Context Protocol (MCP) framework, ensuring seamless interaction with other MCP-compliant AI applications like Claude Desktop, Continue, and Cursor.

⚙️ MCP Architecture & Protocol Implementation

The architecture of the Google Tasks MCP Server is built around the MCP protocol. The server acts as a proxy to the Google Tasks API, translating MCP requests into corresponding API calls. This ensures that various MCP clients can interact with the functionality provided by this server without needing direct access to the Google Tasks API.

🚀 Getting Started with Installation

To get started, follow these steps:

1. Create a New Google Cloud Project: Visit the Google Cloud Console and create a new project.
2. Enable the Google Tasks API: Navigate to the APIs & Services Dashboard and enable the Google Tasks API for your project.
3. Configure OAuth Consent Screen: Create an OAuth consent screen for internal testing if needed.
4. Add Required Scopes: Add the scope https://www.googleapis.com/auth/tasks to grant access to tasks data.
5. Create an OAuth Client ID: Generate a new OAuth client ID of type "Desktop App" from the Google Cloud Console.
6. Download OAuth Credentials: Download the JSON file containing your client's OAuth keys and save it as gcp-oauth.keys.json.

💡 Key Use Cases in AI Workflows

Use Case 1: Task Management for Personal Assistants

Develop an AI-based personal assistant that integrates with Google Tasks to manage a user’s daily tasks. By leveraging the Google Tasks MCP Server, you can create, update, and delete tasks directly from your application's interface, providing users with a seamless task management experience.

Use Case 2: Task Collaboration in Teams

Allow team members to collaborate on shared task lists using an AI-powered tool like Continue or Cursor. Integrating these AI applications with the Google Tasks MCP Server enables them to access, update, and clear completed tasks from any device where the application is installed.
