Google Tasks MCP Server

This Model Context Protocol (MCP) server provides a bridge between Claude and Google Tasks, allowing you to manage your task lists and tasks directly through Claude.

Note: All ( bar some edits ) code in this project was "vibe coded" - generated with Claude with instructions from me.

Setup Instructions

1. Create Google Cloud Project & Enable API

Go to the Google Cloud Console
Create a new project
Navigate to "APIs & Services" > "Library"
Search for "Google Tasks API" and enable it
Go to "APIs & Services" > "Credentials"
Click "Create Credentials" > "OAuth Client ID"
Configure the OAuth consent screen (External is fine for personal use)
For Application Type, select "Web application"
Add "http://localhost:3000" as an authorized redirect URI
Create the client ID and secret

2. Configure Claude for Desktop

Install Claude for Desktop
Open the Claude configuration file:
- MacOS: ~/Library/Application Support/Claude/claude_desktop_config.json
- Windows: %APPDATA%\Claude\claude_desktop_config.json
Add the Google Tasks MCP server configuration:

{
  "mcpServers": {
    "google-tasks": {
      "command": "node",
      "args": ["/path/to/google-tasks-mcp/build/index.js"],
      "env": {
        "GOOGLE_CLIENT_ID": "your_client_id_here",
        "GOOGLE_CLIENT_SECRET": "your_client_secret_here",
        "GOOGLE_REDIRECT_URI": "http://localhost:3000/oauth2callback"
      }
    }
  }
}

Replace the path and credentials with your own values.

3. Build and Run the Server

Install dependencies:

npm install

Build the server:

npm run build

Restart Claude for Desktop

Authentication Flow

When you first use the Google Tasks MCP server:

Use the authenticate tool to get an authorization URL
Visit the URL in your browser and sign in with your Google account
After authorizing, you'll receive a code on the browser page
Use the set-auth-code tool with this code to complete authentication
You can now use all other tools to interact with Google Tasks

Note that your authentication is session-based and will be lost when you restart the server. You'll need to re-authenticate each time.
