Google Tasks MCP

Google Tasks MCP server for Claude Code, Cursor, Copilot and five more AI agents. Connect Google Tasks to Claude, Copilot, Cursor, Codex, Gemini, Windsurf, Continue.dev and Cline. One extension, 8 agents, no config files to edit.

Install. Sign in with Google. Ask your AI agent about Google Tasks.

Quick Start

Install from the VS Code Marketplace or Open VSX
Authenticate: the setup wizard appears on first launch
Ask your AI agent anything about Google Tasks

"What tasks are due this week?"
"List my task lists"
"Show the open tasks in my Work list"

Prerequisites

You need one of these (the wizard will guide you):

Method	Best For	What You Need
OAuth (recommended)	Personal Google accounts	A Google Cloud project with OAuth credentials
ADC	Developers with `gcloud` CLI	Run one terminal command
Service Account	Workspace admins and servers	A JSON key file

Go to Google Cloud Console
Create a project (or select an existing one)
Enable the Google Tasks API under APIs & Services > Library
Create OAuth credentials:
- Go to APIs & Services > Credentials
- Click Create Credentials > OAuth client ID
- Application type: Desktop app
- Copy the Client ID and Client Secret
Configure the OAuth consent screen (if prompted) and add yourself as a test user
In the extension wizard, select "OAuth" and paste your Client ID and Secret
A browser window opens: sign in with your Google account and authorize

Option B: Application Default Credentials

gcloud auth application-default login \
  --scopes=https://www.googleapis.com/auth/cloud-platform,https://www.googleapis.com/auth/tasks.readonly,https://www.googleapis.com/auth/tasks

Option C: Service Account Key

Create a service account in Google Cloud Console and give it access to your Google Tasks data
Download the JSON key file
In the extension wizard, select "Service Account" and pick the file

Available Tools (5)

Tool	What It Does	Example Prompt
`tasks_list_tasklists`	List your task lists	"What task lists do I have?"
`tasks_list_tasks`	Tasks in a list, filtered by due date	"What is due this week?"
`tasks_get_task`	One task's full details	"Show the notes on the tax task"

Tasks Admin (`tasks_admin`)

One tool, called with an action and its params.

Action	Needs `confirm: true`
`create_task(title, notes?, due?, parent?, previous?, tasklist_id?)`	No
`update_task(task_id, title?, notes?, due?, status?, tasklist_id?)`	No
`complete_task(task_id, tasklist_id?)`	No
`move_task(task_id, parent?, previous?, destination_tasklist_id?, tasklist_id?)`	No
`delete_task(task_id, tasklist_id?)`	Yes
`create_tasklist(title)`	No
`delete_tasklist(tasklist_id)`	Yes

Safety

Actions that delete, remove, replace or publish need confirm: true in their params. Without it the server changes nothing and returns a warning, so your AI agent has to ask you and then call again with confirm: true.

Supported AI Agents

The extension auto-registers with every AI agent it detects:

Agent	How It Registers	Config File
VS Code Copilot	VS Code API (automatic)	--
Claude Code	`~/.claude.json`	JSON
Cursor	`~/.cursor/mcp.json`	JSON
OpenAI Codex	`~/.codex/config.toml`	TOML
Google Gemini	`~/.gemini/settings.json`	JSON
Windsurf	`~/.codeium/windsurf/mcp_config.json`	JSON
Continue.dev	`~/.continue/config.yaml`	YAML
Cline	VS Code globalStorage	JSON

You can toggle individual agents on/off in Settings > search googleTasksMcp.agents.

`googleTasksMcp.agents.*`	`true`	Per-agent registration toggles
`googleTasksMcp.registrationScope`	`"global"`	Global or workspace registration
`googleTasksMcp.autoStart`	`true`	Auto-start server on VS Code launch

Commands

Open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for:

Command	What It Does

Troubleshooting

"Google Tasks MCP: Setup" in the status bar

Your credentials aren't configured. Click the status bar item or run Google Tasks MCP: Setup Authentication.

"Permission Denied" errors

Your credentials don't have access to the requested data. Make sure the Google Tasks API are enabled in your Google Cloud project.

Server keeps crashing

Run Google Tasks MCP: View Server Logs to see the error. Common causes:

Expired credentials: run the setup wizard again
Node.js not found: install Node.js 22 or newer

Uninstalling cleanly

Before uninstalling, run Google Tasks MCP: Remove from All Agents to clean up config files.
