Google Tasks MCP Server

A Model Context Protocol (MCP) server for Google Tasks integration in Claude Desktop. This server enables AI assistants to manage Google Tasks through natural language interactions.

Forked from Zach Caceres' (zcaceres) original implementation to enhance authentication handling, add support for multiple task lists, and provide a more robust npm package with Smithery integration for Claude Desktop. This fork is fully functional and properly deployed on Smithery, making it ready for immediate use with Claude.

Features

• List all tasks in your Google Tasks lists
• Search for specific tasks by query
• Create new tasks with title, notes, and due date
• Update existing tasks (title, notes, status, due date)
• Delete tasks
• Clear completed tasks from a task list
• Full integration with Google Tasks API
• Secure OAuth2 authentication
• Docker support for containerized deployment

1. Create a Google Cloud Project and obtain credentials:

   a. Create a Google Cloud Project:

   • Go to Google Cloud Console
   • Create a new project or select an existing one
   • Enable the Google Tasks API for your project

   b. Create OAuth 2.0 Credentials:

   • Go to "APIs & Services" > "Credentials"
   • Click "Create Credentials" > "OAuth client ID"
   • Choose "Desktop app" as application type
   • Give it a name and click "Create"
   • You will get your GOOGLE_CLIENT_ID and GOOGLE_CLIENT_SECRET

   c. Get Refresh Token:

   • Go to OAuth 2.0 Playground
   • Click the gear icon (Settings) in the top right
   • Check "Use your own OAuth credentials"
   • Enter your OAuth Client ID and Client Secret
   • In the left panel, find "Tasks API v1" and select "https://www.googleapis.com/auth/tasks"
   • Click "Authorize APIs" and complete the OAuth flow
   • Click "Exchange authorization code for tokens"
   • Copy the "Refresh token" - this is your GOOGLE_REFRESH_TOKEN

{
  "mcpServers": {
    "gtasks": {
      "command": "npx",
      "args": ["-y", "@alvincrave/gtasks-mcp"],

      },
      "connectionTypes": ["stdio"],
