Google Tasks MCP

English | Русский

A1 Google Tasks MCP lets an AI app manage Google Tasks in plain language. Plan a project as a task list, break work into subtasks with due dates and notes, mark things done and keep everything in order.

It uses the Google Tasks API with your Google account. It separates reversible completion from permanent deletion and makes the limits of the Tasks API explicit instead of implying that every to-do feature is possible.

• 15 tools. List, create and update task lists and tasks, move tasks, manage completion, sweep finished work and reach the raw API when a dedicated tool is missing.
• Completion is reversible, deletion is not. complete_task has an undo (reopen_task); the delete tools are separate and marked destructive.
• Due dates are honest. The API stores only the calendar date — the server never pretends to schedule a time of day; times belong in the notes.
• Minimal Google scope. A single tasks scope, without Drive, Calendar or Gmail access.

Start with a read-only question:

Show me my task lists and everything due before Friday in my default list.

You: What's still open in the "Website launch" list, and what's due this week?

Assistant: Shows the open tasks with their due dates, notes and subtasks. Nothing changes.

You: Add a task "Send the launch announcement" due Friday as a subtask of "Marketing".

Assistant: Shows the target list, the parent task and the proposed task, then asks for confirmation before creating it.

You: Confirm.

Assistant: Creates the subtask with a Friday due date. It does not complete or delete anything unless you ask separately.

Quick start

You need Node.js 20+, a Google account and OAuth credentials from a Google Cloud project with the Google Tasks API enabled.

1. Prepare Google OAuth access.
2. Add the server to your AI app.
3. Ask the read-only question above.

What you can ask it to do

See your lists and plan the day

• Show my task lists and the open tasks in each one.
• What's due this week in the default list? Include subtasks.
• What changed since yesterday? Include completed and hidden tasks.

Create and organize work

• Create a "Website launch" list with tasks for design, content and QA.
• Add a task due Friday with notes, nested under the "Marketing" task.
• Move a task to the top of the list, under another task, or into a different list.

Track completion

• Mark the review task done — and reopen it if the work comes back.
• Sweep every completed task out of the list view in one go.
• Show the hidden tasks that were swept earlier.

How a task changes

1. Tasks live in task lists. Every account has a built-in default list, addressed by the special id @default; create_tasklist adds more.
2. A task carries a title, notes and a date-only due date — the API discards the time portion, so a time of day belongs in the notes.
3. Ordering and nesting change only through move_task; the API's position field is read-only.
4. Completing a task is reversible: reopen_task brings it back. Deleting a task or a list is permanent, and deleting a list removes every task in it.

Recurring tasks cannot be created through the API. Tasks assigned from Google Docs or Chat can be read but not created or moved to another list, and deleting one also removes it in the originating document. There is no server-side search or sorting — the server lists tasks and the AI client filters them.

What can change

The AI client controls confirmation prompts. The server marks reads, writes and destructive tools so the client can distinguish an inspection from a live change.

Getting access

Google Tasks requires OAuth 2.0; an API key is not enough.
