google-tasks-mcp

MCP server for the Google Tasks API. It allows any AI agent (Claude, Cursor, and others) to read, create, update, and delete tasks via Google Tasks.

Tools

Related MCP server: Google Tasks MCP Server

Setup (one-time)

1. Google Cloud Console

1. Go to console.cloud.google.com

2. Create a project (or select an existing one)

3. Open APIs & Services -> Library -> find "Tasks API" -> Enable

4. Open APIs & Services -> Credentials

5. Create Credentials -> OAuth client ID

   • Application type: Desktop app

   • Name: google-tasks-mcp

6. Download the JSON file -> rename it to .credentials.json -> place it in the project root

2. Install dependencies

npm install

3. Authorize (one-time)

npm run auth

A browser window will open -> approve Google access -> tokens will be saved to .tokens.json. After this, re-authorization is not required because tokens are refreshed automatically.

Connect to Claude Desktop

Open claude_desktop_config.json:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

• Windows: %APPDATA%\Claude\claude_desktop_config.json

Add:

{
  "mcpServers": {
    "google-tasks": {
      "command": "node",
      "args": ["/ABSOLUTE/PATH/TO/google-tasks-mcp/src/index.js"]
    }
  }
}

Restart Claude Desktop -> new tools will appear in the interface.

Connect to Claude Code

claude mcp add google-tasks -- node /ABSOLUTE/PATH/TO/google-tasks-mcp/src/index.js

Connect to Cursor / Windsurf / other agents

Any agent that supports MCP (stdio transport):

{
  "mcpServers": {
    "google-tasks": {
      "command": "node",
      "args": ["/ABSOLUTE/PATH/TO/google-tasks-mcp/src/index.js"]
    }
  }
}

Example prompts for your agent

"Show all my tasks for this week"
"Create a task 'Open PR' with deadline 2026-03-05"
"Mark task X as completed"
"Move task Y to the top of the list"

Security

• .credentials.json and .tokens.json must never be committed (already in .gitignore)

• Tokens are refreshed automatically via the googleapis OAuth2 client
